Ziguangdayuan is a new eggplant variety bred by vegetable experts from Hebei University of Engineering. It has strong growth potential, medium maturity, and fruit set of 9 to 10 leaves. Product fruit 0.6 ~ 1kg, maximum 2kg, fruit nearly round, fruit surface smooth, purple black flash, no white top, delicate fruit, milky white with light green, very few seeds; high resistance to browning, cut open after 24h does not change color . Over the years, our research group has carried out cultivation experiments and research on different types of open fields, greenhouses, greenhouses and other methods for this species. Among them, the cultivation techniques of open field cultivation are simpler, less risky and less investment than the facilities. The output per 667 square meters can reach over 7500 kg. , The output value of 3200 ~ 4200 yuan, remove the cost of 320 yuan, income of 3500 yuan. The variety and its spring dew-growing cultivation methods have been accepted and recognized by the majority of eggplant farmers in recent years, and have been planted throughout the country. North China and Northeast China have been widely used and promoted.
1 Nursery
1 nursery facilities Yangshuo or greenhouse for seedbeds.
2Cultivate the soil with 60% of the fertile soil without planting solanaceous vegetables and 40% of the decomposed organic fertilizer as the culture soil. Add 1 kg of phosphate fertilizer, 1 kg of diammonium phosphate, 10 kg of puffed chicken manure to every 1 cubic meter of culture soil. Ash 4kg (or potassium dihydrogen phosphate 0.5kg). After sieving, dope and spread 8cm thick on the seedbed.
3 soaking germination first with warm water (25 ~ 30 °C) soaking 15min, then add 55% hot water hot seeds (water volume is 8 to 10 times the seed), stirring constantly, cooling to 30 °C to stop, soak in water for 8h. Remove and wash with water several times, rinse and dry. Squeeze the clean cloth with hot water, remove the water, wrap the seeds, and germinate. The germination temperature is 30°C. Conditional variable temperature germination: 16h at 30°C, 8h at 20°C, better. Sprout 50% to sow.
4 sowing in North China generally from mid-January to mid-February, select sunny morning sowing, generally 4 to 5 days earlier to germinate. A few hours before sowing, the wells should be soaked with well water, and after the infiltration, a thin layer of fine soil should be sprinkled and sprayed with 50% carbendazim 500 times. 7 days before sowing, Yangshuo will cover grass and grasshoppers at night, and grass curtains will be used for drying in the daytime. The buds were evenly sowed (the seed germinating area per 1.5g seeds was 1.5 to 2 square meters), and the fine fluvo-aquic soil was 1cm after sowing. After the completion of the broadcast, the Yangshuo film will be buckled and the grass will be covered in the evening and the grass will be pulled after sunrise.
5 Seedling management timely exposing and covering the grass every day to remove dust on the membrane. 50% to 60% remove the mulch in time after emergence. Cotyledons were sprayed with thiophanate-methyl 800 times. The cotyledon was expanded to two true leaves. During the day, it was higher than 28% to release air. During the day, it was maintained at 25-26°C and nighttime at 10-14°C. After the first true leaf flat, proper thinning. Pull out the seedlings can be planted in the lack of seedlings. When the two leaves were sprayed with potassium dihydrogen phosphate (50 g of potassium dihydrogen phosphate against 15 kg of water) or Spruce 120 and Kamo harvest. At the time of 3 to 4 leaves, the outside temperature is already high, and the amount of air is gradually increased to prevent the high-temperature burning of seedlings during the day and freezing injury at night. In the spring, the wind is big and it is necessary to press the membrane tightly to prevent the wind from blowing off. Seedlings generally do not water, but if the seedlings are found thick, slow growth, soil drought, watering in the sunny morning, flood irrigation is not allowed. 2 to 3 leaves when the seedlings (transplant to Yangshuo, that is divided into seedbed). Each planted 667 square meters of eggplant needs a seedbed area of ​​20 square meters. Bed soil seedbeds. The seedling rows were 10cm10cm apart. After the seedlings were watered in a timely manner, the film was covered, and the grass was covered at night. After the easing of seedlings, the amount of air is gradually increased during the day. Spray 3% when 3 to 4 leaves. Potassium dihydrogen phosphate solution. 7 days before planting, increase the ventilation and hardening of seedlings, according to the weather 4 days before planting, the membrane can be smelted seedlings, leaf spray. 5 to 6 leaves. After the Ching Ming period, they can be planted in Daejeon and covered with plastic film. Small sheds can be planted 7 days earlier.
2 Colonization
1 Soil preparation Fertilize the land in winter and turn it deep in the spring to 25-30 cm. Before planting, combined with soil preparation, every 667 square meters of fermented organic fertilizer 4 to 5 cubic meters, superphosphate 50kg, urea 25kg, potassium sulfate 20kg. It is better to apply 200-300kg of cake fat per 667 square meters. After fertilizing and cultivating, the seedlings are leveled and then ridiculed. The sorghum is laid at 80cm spacing and 100cm spacing, and the ridge height is 12 to 14cm.
2 Transplanting Planting Planting the seedlings by planting at a distance of 40 cm. When the seedlings are planted, the roots of the soil shall be kept intact, and the soil shall be sealed to the top 10 cm above the seedlings.
3 Field Management
1 A cultivator is conducted 3 days after cultivating and planting to increase the temperature and promote seedlings. After easing the seedlings, the cultivator shall be cultivated once, and the cultivars shall be cultivated in combination with the cultivator in order to grow roots and prevent lodging.
2 After the pruning of the whole pruning door, leave the 1st and 2nd branches and remove the other side branches below the door, and the side branches above the door must not be pruned. The old leaves below the position where the eggplant is harvested should be removed promptly.
3 Watering Fertilization Seedlings are generally not watered until flowering, but the fruit and fruit growth during the fruiting and fruiting period have a greater demand for fertilizer and water. It is necessary to timely watering according to soil moisture, plant growth, and precipitation, so that soil moisture can be kept in the field. About 80%. Generally, it is top-dressing when the door egg sits, such as eggs, and 667 square meters chases urea 10kg and potassium sulfate 10kg. After sitting on the eggplant to catch a fertilizer, the amount of fat is the same as above.
4 Prevention and control of pests and diseases Pests and diseases occur less frequently, mainly brown streaks and tea scutellariae. Brown Vegetation: Early removal of diseased leaves, removal of diseased plants, or deep buried or burned. In severe cases, spray 75% chlorothalonil WP wettable powder 600 times, 40% methicone wettable powder 600-700 times, 64% WP wettable powder 500 times or 1:1:200 Bordeaux. Liquid, generally 10 days against 1 time, rotation use, even spray 3 times. Tea saponin: sprayed with 1.8% avermectin emulsifiable concentrate 3000 times solution or 15% fluorenone emulsifiable concentrate 1500 times solution. Damage young fruit, pay attention to early prevention and treatment. And timely clear the fruit affected by aphids.
5 Harvesting and harvesting will affect the yield too early, and the quality will decline too late. It will also affect the growth and development of the rear solanaceous fruit and also reduce the yield. Appropriate harvesting period depends on the "Vegetarian Eye" (the colored ring at the junction of the sepal and the fruit), and the ring is white or light green. Obvious zoning indicates that the eggplant is still growing, and the ring is narrow or not obvious, indicating that the growth of eggplant has slowed down and should be picked in time. When picking market prices, good prices can be appropriate early mining. The eggplant should be properly harvested early, which is beneficial to the development of the plant and the results. Harvesting is best in the morning, because at this time, the fruit is full, the luster is bright, and the merchandise is good. It is generally 500g in the door tomato, 750 ~ 1000g tomato timely harvest.
