North Wubei Schisandra is a precious Chinese herbal medicine. It has a long history of application in traditional Chinese medicine, has a wide range of applications, and has a large amount of use. Because of its beneficial effects on the human body in many ways, it has become more widely used. Schisandra chinensis is not only used as a Chinese medicinal material, but also widely used in alcoholic beverages, fruit juices, and the like. Being listed as the third generation fruit tree, it is a new economic plant with high application value and broad development prospects. Due to the increasing market demand, people's picking enthusiasm has been stimulated. As people's awareness of protection of wild resources is weak, grabbing green harvesting and predatory harvesting have resulted in a sharp decline in the number of originally limited wild resources and the emergence of North Schisandra resources. The shortage is serious. Some pharmaceutical companies have failed to produce and raw materials are in short supply. In addition to the large number of domestic pharmaceutical companies, North Korea has also imported a large number of countries such as South Korea and Japan. As a result, the market price has risen sharply, and the contradiction between supply and demand has become prominent. The only way to solve the shortage of raw materials is to artificially cultivate Schisandra chinensis. North Wubei Schisandra artificial cultivation has a history of many years, under the full light of S. chinensis sexual training seedlings, park construction, pruning, cultivation and management, pest and disease prevention, how to improve the survival rate, the results after transplanting two years and other key The success of the technology provided a scientific basis and technical guarantee for the large-scale cultivation of Schisandra. Through scientific cultivation of Schisandra chinensis, high-quality products with high yield, no pollution and no pesticide residue are produced. Make full use of barren hills, flat lands, forests, and houses in front of houses to cultivate Schisandra chinensis. North Wu from the current look at Schisandra only annual demand in China is 8,000 tons, while China's annual purchase of only 500 tons, and the demand is showing an upward trend year by year. 500 acres of schisandra chinensis planted, with an investment of about 2,000 yuan per acre, the second year after planting can be the result, the third year more than 300 kg of dried fruit per mu, the fourth, five years into the high yield period, per mu 500-600 kg of dried fruit The mu income is about 20,000 yuan, and it can be harvested continuously for several decades. The cultivation method of Schisandra chinensis is simple and easy to manage. It is a good project that has been invested for many years. Chapter II Biological Characteristics of Schisandra North Schisandra has vegetative organs and reproductive organs, roots, stems, and leaves belong to vegetative organs, and flowers, fruits, and seeds belong to reproductive organs. 1. The roots of Schisandra chinensis, which are the roots of the North Schisandra, are tan and rich in fleshy. The root system has a fixed plant that absorbs water and mineral nutrients, stores nutrients, and synthesizes various amino acids and hormones. 1, the type of root (1) the root system. The seedling roots develop from the radicles of the seed. When the seeds germinate, the radicles are rapidly produced and penetrate deep into the soil to become the main axis. After a few days, a lateral root is formed near the root neck, and then a dense lateral root group and a strong root system are formed. The root system of the seedlings of Schisandra chinensis also consists of the main root and the lateral roots just like other plants. Since the lateral roots are very developed, the main roots are not very obvious. (2) Indefinite root system. The adventitious root system refers to the root system of the nursery stock obtained through the insertion and the infusion of the schisandra, and the root system that is sent out from the stem through the underground. This kind of root system is formed by the adventitious roots produced on the stem, so it is also called stem source root or nutrient root system. The root system of this seedling consists of roots and all lateral and juvenile roots. It has no main root. 2. Distribution of Root System in Soil The root system of Schisandra chinensis changes with the climate, soil, groundwater level, and cultivation and management methods. Each tree generally has 4-7 roots, and the diameter is more than 3 mm. Roots do not produce fibrous roots, can produce roots less than 2 mm in diameter of the transmission roots, less than 2 mm in diameter on the roots of roots. Roots are concentrated in soils 5-40 cm deep. The roots can be distributed within 1 meter from the rhizomes and 50 centimeters from the rhizomes. The root system of P. chinensis has strong fertility. A large number of root systems are distributed at the sites where fertilization is concentrated to form lumps. Strengthening soil tillage and increasing the depth and breadth of fertilization can effectively induce the development of the root system, facilitate the nutrient absorption of the root system, and increase the ability of the plant to drought. The distribution of adventitious roots on stems of Schisandra chinensis is shallow, mainly concentrated in the soil of 5-15 cm. When the fertilization is shallow, it will easily cause nutritional competition. Second, the North Schisandra stems Schisandra is a woody tussah, stems slender, soft, can not be independent, need to attach to other plant body winding upward growth, so usually the stem is also known as vines. The stalks of the aerial parts are morphologically divided into trunks, main vines, lateral vines, resulting mother twigs and shoots, and new shoots can be divided into result branches and development branches. The branches emerging from the ground are called trunks, the main vines are the branches of the trunk, and the side vines are the branches of the main vines. As a result, the mother shoots grew on side vines, a mature shoot from the previous year. A new shoot from the resulting tooth on the mother branch is called a result branch with the ear, and a development branch with no ear. Shoots that sprout from the stems of plants are called sprouting shoots. The stem of Schisandra sphenanthera is relatively weak, and when the new shoot grows to 60-70 centimeters, it needs to be wrapped around other wood or branches in a clockwise direction in order to grow normally. The underground mold of the Schisandra chinensis is tan-colored, with its front end flattened, and the tenderer is a growing point that extends forward. It expands horizontally in the soil at a depth of 5-15 cm below the surface and is the main organ for asexual reproduction. In the case of artificial cultivation, it can be used to elicit the characteristics of sprouting twigs, select the remaining branches, and update the growing vine. Unnecessary sprouting branches promptly eradicate, so as not to compete for parent nutrients. Third, the buds and flowers of the North Schisandra 1, the buds of the buds of the North Schisandra are conical, and the outside is covered by several scales. There are three buds in the shoot of new shoots, the main buds are well developed in the middle, and the smaller buds are on both sides. The main buds germinate in spring and many sprouts do not germinate. When the main bud is injured, the secondary buds can germinate. The buds of Schisandra chinensis are divided into taste buds and flower buds, and the leaf buds are thin and not full, while the flower buds are round and full. The Schisandra chinensis is a mixed flower bud. Before flowering, it has completed floral differentiation and wrapped several small flower buds under the scales. Ungerminated primary buds, deputy buds, and thickened branches are hidden in the cortex and can germinate under certain conditions. Such buds are called secreted or dormant buds, and latent buds. The new shoots extracted from the germination of the buds are generally thick, and have more leggy, which can be used for the regeneration of shoots. 2. Flowers of Schisandra sphenanthera unisexual, monoecious, usually 4-7-flowered at base of new shoot. The proportion of male and female flowers differs depending on the state of differentiation. Flowers full white or pink. Male flowers have stamens of about 2 mm in length, 5-6 anthers, and are erected on top of columnar receptacles about 0.5 mm long to form a group of stamens. Female pedicels, petals and male flowers resemble mulberry in the middle, with a round shape. The differentiation ratio of female flowers and male flowers of Schisandra chinensis is closely related to the nutrition, light, temperature, moisture, and endogenous hormones of the tree. The results of large or poor management of the individual Schisandra chinensis may easily result in years of age. In the second year of the year tree, the number of female flowers decreased significantly, and even the whole plant was male. Fourth, the leaves of Schisandra chinensis are the main organs for photosynthesis and nutrient production. The leaves are membranous, elliptic, ovate, or suborbicular, and the veins of the web are not obvious. The leaves of Schisandra chinensis are shade-tolerant and light-loving. Different illumination has a significant effect on the photosynthesis of the leaves, directly affecting the differentiation quality of the shoots and also has a great influence on the growth of the plants. Therefore, the production should be reasonably pruned. Improving the ventilation and light conditions of the shelves to enhance the photosynthesis of the leaves is very important for the quality and high yield of Schisandra. Chapter III Breeding Techniques of Schisandra chinensis By artificial cultivation of Schisandra chinensis, the method of sexual reproduction is best. In the sexually propagated Schisandra chinensis seedlings, the roots are well developed, and the buds are full, with strong vitality, and transplanted to survive. The rate is high. 1. Seed treatment At the end of August-September when the seeds of schisandra fruit are mature, mature fruits are harvested, the skin of the peel is removed, the grains are rinsed, soaked in fresh water for 3 days, and the pulp on the seed coat is soaked and cleaned. The 1:3 fine wet sand is mixed and mixed (the humidity of the sand is suitable to be mixed with light by hand.) Then mix the seeds in a wooden box or in a breathable woven bag, place them in a cool room, or dig in a 50-80 cm deep pit, shade the top and cover with 20 cm soil cover before freezing. Pay attention to the fact that the seeds maintain the humidity and naturally they can pass winter. The storage time is not less than 90 days, and the seeds are removed about 10 days before sowing to increase the humidity and temperature. When most of the seeds are cracked or exposed, the seeds can be sowed. Second, the nursery to choose to cultivate excellent Schisandra seedlings, nursery best choice flat terrain, convenient drainage of water sources, loose soil, fertile sandy loam soil and black humus as well, so that the deep plowing, fine, Mushi well cooked Farmyard fertilizer 5000 kg. Or compound fertilizer 80-100 kg. Third, the open live live exposed before the open air is not limited to the length of 1.2 meters wide, 25 cm high seedbed, sowing can be used to drill or sow. Drilling is conducted at a spacing of 15-20 cm and a ditch depth of 3 cm. The seed is evenly spread into the ditch. The amount per mu is 12-15 pounds. After sowing, cover 2 cm thick fine soil, crack it with wood, cover with a layer of pine needles or straw, straw curtain, and drench the water. Keep the humidity and then see the soil dry. In order to prevent seedling blight and other diseases after sowing in combination with water spray 800-1000 times on behalf of Zinc or the enemy pine water agent to prevent disease. The cover was removed when the emergence rate reached 70%. (Thinner grass can not be withdrawn), until the seedling grows to 5-6 cm when the true leaves form, timely weeding weeding. Appropriate foliar fertilizer and pest control. Chapter IV Establishment of the North Schisandra Garden North Schisandra cultivation is a project that has invested for many years and has benefited from a large amount of investment. Therefore, it is very important to choose a site and build a garden. I. Land Conditions The soil in the natural distribution area of ​​Schisandra chinensis is mostly black humus black humus soil, which is slightly acidic and acidic soil. It has characteristics of good permeability, strong water retention, good drainage, and high humus content. The practical experience of artificial cultivation proves that the requirements for the drainage of soil from the schisandra chinensis are extremely strict, and the stumbling block where the water is accumulated is not suitable for cultivation. Slopes, flat lands, and front and rear houses with the above conditions should be selected. Second, the water conditions of North Schisandra is more drought-tolerant, but in order to make plants grow well and get high yields, during the growth period must supply sufficient water. Especially in the spring drought season each year, it will affect the growth of S. chinensis and its fruiting and fruiting. At the same time, in order to control the pests and diseases of the Schisandra chinensis, spraying a drug also requires a certain amount of water. Therefore, when setting up a park, consider where there are enough water sources, such as groundwater, rivers, reservoirs, etc., to meet the water requirements of the North Schisandra. In addition, it is also necessary to pay attention to the drainage facilities and irrigation facilities in the park. Before the onset of the rainy season, ditches should be dug. For the poorly-drained plots, large-scale and high-bed methods should be adopted. Irrigation facilities can be spray irrigation, micro-spraying, drip irrigation, etc., but also can use the traditional open ditch irrigation method. III. Preparation before transplanting 1. Level the land before leveling the land, clean up the weeds, stones and other debris in the week, fill in the potholes and ditch as much as possible to make the land flat and easy for future operations. Second, fertilization from Oubei Schisandra is a perennial plant. Once planted for continuous production for several decades, the water and nutrients needed for the growth and development of Schisandra chinensis are absorbed from the soil by the root system. Therefore, the fertilization before transplanting is beneficial to the growth of Schisandra. The main application of decomposed pigs, sheep, horses, cattle, chicken manure can be. Chemical fertilizers, such as corn and soybean compound fertilizers, can also be used to make compound fertilizers by using urea, diammonium, and potassium sulfate. 5000 kg of farmyard fertilizer per acre, 80 kg of compound fertilizer. It can be applied during ploughing, or it can be inserted into a cultivator when it is smashed. For example, a small amount of manure can be applied to the transplanting hole by grasping the manure. It is advisable to use a 1.30-meter to 1.50-meter line spacing at the start of the cockroach, and a cockroach about 90 centimeters wide. If you want to interplant other plants with shorter plants in the schisandra line, you can reduce the size of the cultivated maggots and leave a small row of pods for interplanting to make full use of the land. Third, the frame column, the line of schisandra cultivation in the beginning after the completion of large cercariae can be started to bury the frame column, you can also transplant schisandra seedlings planted after the erection of framed columns, but should be vacated first to lay the column, in order to avoid transplanting After the seedlings are affected. 1, the preparation of the frame column can be used wooden column, can also be used cement column. Wood frame column can be used hardwood, small diameter of about 10 cm can be stripped off the bark, the bulk of the asphalt can be used to brush, or use a fire to prevent decay to extend the useful life, so that the cement column investment is small. The cement frame column can be made by itself. Each column of cement can produce about 7 square columns. The production of coarse sand can be done. The number can be set between four 8 or 10 iron wire, square column 88 or 1010 cm, 2.5 meters high. . 2, buried method. When the pillars are buried, the standard stakes are buried first, and then buried sequentially at a distance of 6-8 meters. The pillar pits are 50-60 cm deep, and two ends of each row of columns are tied with 8-10# wire anchors to fix the frame to prevent spuriousness. 3, the method of wiring. After the pillars are buried, they can be racked on the rack and can be pulled on two or three lanes. The first road is 60cm from the ground, and the second one is about 15-20cm from the top of the column. Three lines can be added in the middle. Both the upper line and the lower line are connected with the ground anchor line to play a fixed role. IV. Colonization and management of Schisandra chinensis seedlings 1. Planting techniques. The schisandra has been planted in the spring for many years. After years of practical experience, it can be transplanted in autumn and in summer, and the survival rate is also very high. The spring planting is generally from early April to early May. At this time, the transplanting temperature is low, the sprouts of the seedlings have not yet germinated, and the moisture in the soil is sufficient. At this time, the survival rate of transplanting is higher. (1) Seedling treatment. Dehydration may occur after the seedlings are purchased. In order to facilitate the sprouting of the seedlings and soak the roots before planting the seedlings, soak the whole plant for 12-24 hours. Add the rooting powder or rooting treasures when soaking to promote the early survival rate and increase the survival rate. (2) Digging planting holes. On the well-established cultivars, the grazing spots are arranged at a distance of about 50 cm. The size and depth of the burrows are determined according to the size of the root system of the seedlings, generally 30 cm deep and 30-40 cm in diameter. Each hole can be put into a hot farmhouse fertilizer and soil mix. (3) Planting methods. The wells will be backfilled with a good part of the soil, the seedlings can be placed directly, can also be slanted, slanting method is simple, easy to spread the roots of seedlings conducive to growth, the seedlings put the soil covered in the extended root system , compaction, surrounding the seedlings with soil round water dish, irrigating the water. After the water completely infiltrated, lay the water pan flat. In the process of transplanting, we should pay attention to putting the seedlings in the bucket and put less water in order to avoid the roots of the seedlings from being dried and affect the survival rate. The advantage of transplanting in autumn is that the seedlings go into dormancy, and they can grow in the second spring without slow seedlings, and the survival rate is high. Transplanting in summer is to be transplanted during the rainy season. (4) Management after planting. The roots of Schisandra sphenanthera are very underdeveloped, and the branches and branches are also relatively weak. In the first year after planting, the growth is weak. Only by strengthening management can we achieve a long-term growth and ensure the survival rate. After the planting of Schisandra chinensis, the dry treatment should be carried out. In order to reduce nutrient waste and promote the renewal of the main vine, the schisandra seedlings should be selected and retained at the base of the seedlings. Shovel soil loosening throughout the year to prevent weed growth. Soybeans, vegetables, melons and low plants can also be interplanted to increase land utilization. Seedlings can survive in the late May in each plant topdressing urea, potassium sulfate, each 10-20 grams, dressing pit 30 cm away from the seedlings, too easy to burn roots. In the second half of July, fertilizer can be traced twice, and 20 grams of diammonium phosphate and potassium sulfate can be applied. Watering in the spring in case of drought, and removing water from the rainy season, it is easy to cause seedling death. The annual growth rate of seedlings of Schisandra chinensis can reach 50-100 cm in one year, and it can reach 1 meter-2 meters in height in two years. When the length of the newborn vine spreads to about 50 cm, it must be wound up and attached to the stent. If the stent is not established in time, it will automatically cap and stop growing. Therefore, it is necessary to set up the stent in advance for the normal growth of the plant. The seedlings and diseases of Schisandra chinensis seedlings are rarely found under normal circumstances, but since 1-year-old seedlings are delicate, once a pest or disease occurs, it will have a great influence on its growth. Therefore, prevention should be done so as not to affect the growth and survival rate. Chapter 5 Management Techniques of Schisandra chinensis First, Schisandra chinensis is a perennial plant, and the branches are slender and soft. In wild conditions, their branches must adhere to trees and grow clockwise so that they must be cultivated artificially. The establishment of stents, the establishment of stents can maintain a certain tree shape, branches and leaves have a reasonable spatial distribution, to obtain adequate light and ventilation conditions, but also easy to field operations management. The cultivation of schisandra chinensis uses a hedgerow method, which raises the height by 2 meters and pulls 2-3 lines of iron wire horizontally to fix the pole. This type of racking is conducive to ventilation and light transmission, improves fruit quality, and reduces pests and diseases. Second, the plastic schisandra twigs can not stand upright, need to rely on the stent winding growth, it should be the first stand frame rods can be used to resist rotting rough wooden bar, bamboo or nylon rope, wire can be, the current use of bamboo rod , life of up to 6 years. The pole height is 2.2 meters and the small head diameter is 1-2 centimeters. Use a wire tie to fasten the pole to the wire. 1-2 roots per plant. Each seedling is left with two robust main vines. With one pole, two main vines can be twined together. With two roots, two main vines can be wrapped around two poles. The use of 2 poles facilitates pruning management, which is more conducive to ventilation and light transmission, but only twice as much investment in poles. The main vines grow on the poles, and the individual main vines that cannot be wrapped are bundled to guide the winding growth. When the schisandra enters the autumn, in order to promote its stout sturdy, full of shoot buds, and estimate the local climate, about a month before the next frost, the schisandra of the schisandra is treated with a cusp tip so that its absorbed nutrients are transferred to the limited stem. The vines promoted robustness, full sprouts, and lignification. If not treated with axillary tips, the top part of the stems did not form lignification, and there was a phenomenon of dead shoots after winter, and stems and buds were thin and weak. When the schisandra seedling grows to a height of 1.5 to 2 meters when it is in a good condition, the flower buds can be seen in full bloom, and the result can be obtained in the second, but the yield is low. III. Trimming of Schisandra chinensis The pruning of Schisandra chinensis is to maintain a good tree shape, to facilitate management, and to make the mother branch reasonably distributed. According to the tree vigor of the plant, the number of branches and the length of the result, a reasonable number of branches should be properly selected. In order to maintain a balanced growth, to achieve high yield, stable production, high quality, to avoid the phenomenon of size. 1, pruning time. Schisandra pruning is usually winter or spring shearing and is performed once per growth cycle. After falling leaves in the autumn, the weather gradually becomes cold and the plants go into a dormant state and can be pruned. After pruning in the spring, the plants were trimmed before sprouting. 2, pruning method. In general, 1-4 shoots were cut from short shoots at the base of the shoot, and 1-2 shoots were cut for short shoots, and 5-7 shoots were cut for the shoots, leaving 8 More than one bud is pruned by long shoots, and 15 buds or more are reserved for super long shoots. The schisandra chinensis is mainly pruned by middle and long shoots, and the long, medium, and short shoots should be pruned on the same plant according to actual conditions. When trimming, cut the mouth 2-2.5 cm away from the buds and leave no branches within 30 cm from the ground. When the branches are not covered, the sprouts on the extension branch of the main vine tend to cause depression on the shelf, affect the ventilation and light, and cause nutritive waste. Therefore, the litchi must be cleared in time to ensure the normal lighting of the shelf and Reduce nutritional competition. Soil Management Soil is the basis for plant growth. Deep soil, loose soil, good ventilation, favorable for root growth, enhanced metabolism, play an important role in the growth of the North Schisandra and yield and fruit quality. Therefore, according to the growth and development characteristics of the North Schisandra, the nutritive state of fertilization, irrigation and field management can ensure high yield, stable production, high quality and high efficiency. 1, fertilizer. The Schisandra chinensis grows when the supply of nitrogen fertilizer is insufficient. The growth of shoots is thin, the leaves are small and the color is light, the growth is terminated prematurely, the fruit grains of the ear are also small, and the yield is obviously decreased. When there is too much nitrogen fertilizer, branches and leaves are long and unrealistic and susceptible to disease. The Schisandra chinensis begins to absorb nitrogen almost at the same time during the year, and the nitrogen fertilizer is the most demanding from the exhibition leaf to the flowering period. Therefore, nitrogen fertilizer should be applied before the beginning of growth. The plants can form robust shoots and well-developed flower buds in the early growth stage, laying the foundation for fruit set and fruit growth. Generally, the application of diammonium phosphate in early May and early July is very effective. The Schisandra chinensis began to grow from the early spring shoots until the berry ripening period and absorbed phosphorus, which was absorbed most during the vigorous growth period and berry swelling period of the new shoots. Diammonium phosphate may be used during topdressing, and potassium dihydrogen phosphate may also be sprayed on the leaves. Potassium fertilizers are absorbed during the growth of Schisandra chinensis. With the berry swelling, the potassium absorption also increases significantly. In the growth process of Schisandra chinensis, during the top dressing in May and July, potassium sulfate was added to diammonium phosphate. It is also possible to spray potassium dihydrogen phosphate on the foliage. The amount of topdressing increases the amount of topdressing as the tree grows. In the process of growth, if the phenomenon of defertilization of the plant can be found combined with the method of foliar fertilization, a small amount of urea is added at the same time when the fungicide is sprayed. The effect of potassium dihydrogen phosphate is obvious, and foliar fertilizer with other trace elements can also be added to the foliar. top dressing. 2. The water-resistance of Schisandra chinensis is strong in drought resistance, and the cultivation is performed with excellent soil. Even if watering is not performed throughout the year, high yield and quality will be obtained. However, due to the relatively small amount of rainfall in the spring, dry weather and large winds, the province is prone to drought, and it is very unfavorable to the growth of Schisandra. It can be used for irrigation when the soil is dry, which plays an important role in improving the yield and quality of Schisandra. The schisandra chinensis is particularly sensitive to the response to moisture in the buds, during the rapid growth period of the shoots and during the swell of the berries. The lack of water in the early growth stage will result in irregular shoots, short shoots and leaves, and reduced fruit set rate, which will have an impact on the current year's yield. Water shortage during ripening can delay maturation and reduce fruit quality. Therefore, in the whole growth process of Schisandra chinensis, in case of drought, it should be watered in time, and furrow irrigation, sprinkling irrigation, micro-irrigation, or drip irrigation can be used to ensure water and water resources. 3. Remove sprouting sorghum After the second annual growth of S. sphenanthera, during the growing season, underground stems will produce a large number of sprouts. If not removed in time, it will cause nutritive waste and affect the ventilation. When shoveling, use a spade shovel. V. Pest Control The common diseases in the artificial cultivation of Schisandra chinensis are black spot, powdery mildew, leaf blight and other diseases. Insect pests such as Ligustrum lucidum, chafer, etc. 1, black spot black spot disease occurs generally in April - August months, leaf disease generally start from the tip and leaf margin, leaf surface with black spots, the beginning of an irregular round and oval black spots, With its expansion, multiple lesions merge into larger lesions, which are brittle when dry, and have black mould on the back when wet. When the fruit is infected, the fruit surface forms a light-colored chlorotic dot that expands. The diseased area was sunken and turned brown. When it was severe, the seeds were exposed and a great deal of fruit was dropped. After the occurrence of the disease, it caused serious consequences such as falling leaves, falling fruit, dead shoots, declining tree vigor, falling fruit quality, and reduced yield. The prevention and treatment method is to use 50% mancozeb WP before and after the onset of 500-600 times the liquid, while spraying the foliar spray control effect is obvious. 2. Powdery mildew The main pathogenesis of powdery mildew is from May to June. It often occurs after the fall. It mainly damages the leaves, fruits and shoots of the schisandra. The bacteria usually begins to infect from the young leaves. Acupuncture-like spots appear on the back of the leaves. , gradually covering the white powder, when covered with the entire blade. The diseased leaves turn green from yellow, curl up, wither and fall off. From the onset of disease, this disease occurs in dense dens, excessive leggy, excessive nitrogen fertilizer application, and poor ventilation. The method of preventing powdery mildew is that the powder can be sprayed with 20% wettable powder of triadimefon or thiophanate-methyl, carbendazim, and has better control effect. If the effect is not obvious, two bactericides can be mixed and sprayed. 3, leaf blight disease generally occurs in the 5-7 months. The tip of the blade and the edge of the blade become yellowish-white, and the diseased part is brittle and cracking occurs, and gradually spreads to the entire blade. Caused by the leaves withered off, affecting plant growth. Control methods: Use thiophanate-methyl or mancozeb zinc for foliar spray before and after onset. 4. Ligustrum lucidum is a kind of important pest in the cultivation of Schisandra chinensis. It damages fruits, fruit stems and seeds with larvae. The larvae penetrate into the fruit to form a 1-2 mm scar on the surface of the table, feeding the flesh, causing the fruit to rot and dry, the stiff fruit to remain on the ear, and destroying the whole ear, which reduces the yield and degrades the quality. Control methods: After deciduous leaves of Schisandra chinensis, the fields are thoroughly cleaned, the leaves are destroyed, the insects are eliminated, and the source of insects is reduced. Can also be spraying pesticide pyrethroid insecticide in the whole growth period, spray once in 15-20 days, the control effect of more than 90%. Chapter 6 Harvesting of Schisandra chinensis Fruit harvest time directly affects its quality. If harvesting is too early, the dried products processed into poor color, hard texture and low drug content. Late harvesting can easily lead to partial loss of fruit and economic losses. It is generally harvested from the end of August to the middle of September, when the fruit ripens soft and flexible, and the appearance is red or purple, which can be timely harvested. Choose sunny days when harvesting, picking bunches of fruit in bunches to minimize damage to the leaves. Harvested ears can cool naturally. Dry or dry in case of rainy weather. Drying temperature should be below 40 °C is appropriate. The fruit is dry and hand-twisted. It is advisable to loosen it and restore it. Remove the handles, impurities, etc., ready for sale. The dried schisandra products of schisandra are purple-red, grainy, fleshy, oily, shiny, and have aromas of schisandra. They have less dry stems, no branches, no impurities, no insects, and no mold becomes quality goods.
