Department of commonly used bulk Chinese herbal medicines, edible can also be used as medicine. According to the data provided by the national census data of the Chinese medicine resources, the annual sales volume of the product reached 10 million kilograms. The cultivation method is as follows:
First, the election site preparation
茯苓 It is advisable to choose a well-drained 10-25 hills in the east, south and west directions for the planting site. The soil is good for yellow sand, clay, gravel soil is not suitable for planting, and it is not suitable for continuous cropping. After selecting the land, it is necessary to remove the impurities when deep-dumping, and use termite-killing drugs to disinfect the soil in areas where termites are harmful. In the 10 days before the inoculation, we will turn it over once again to break up the soil and completely remove the impurities.
Second, stock preparation
The growth of the fungus depends on the pine wood to provide nutrients, therefore, the cultivation of earthworms should be based on pine trees. The production is mainly divided into dry-segment wood cultivation and tree shrub cultivation.
1. Dry section wood preparation method Select a pine tree with a diameter of 12cm or more to cut down (or leave the head and tail), cut off some of its branches, leave the leaves of the tree's tail, and then use a spatula to shovel the size of the tree. Go 4 to 5 bark (preferably shovel to xylem), leave 4 to 5 pieces of bark with two finger widths between the scoops, and there should be no break marks from top to bottom. The left bark is called lead. (commonly known as "retention bars"). After 10 to 15 days, until the trunk has dried to the point where there is a crack, it is sawn to a small section of 70 to 80 cm, and piled on the dry sunny side by "well" shape. Duan Muxi was covered with forage grass, a drainage ditch was opened around the raft, and termite drugs were sprayed on the ground.
2. When trees are cut in the autumn and winter seasons, the tree shrubs and cutting methods select stumps with a diameter of 12 cm or more, remove the weeds and topsoil in the range of 1 to 5 m around them, cut off the shrubs, and dig deep for about 0.8 m to make the stumps. The roots are exposed outside the soil. Then shovel 4 bark on the stump, leaving 4 fingers with two fingers wide. Roots exposed to the ground to stay up to 4 to 6, cut off the rest of the root. The roots of the tree are also to be scooped on three sides, leaving 1 finger thick lead on the left and right sides, and the length of the root is 1 to 1.5m. All the above tasks should be carried out in the winter of last year.
Third, inoculation
1. Inoculation season
Inoculation is divided into spring and autumn. Spring planting is conducted from the Ching Ming to the beginning of summer. Temperatures in south Guangxi, southeastern Guangxi, and western Guangxi recovered earlier and were more suitable for inoculation before and after the Ching Ming period. In the north of Guangxi and northwest of Guangxi, it was appropriate to inoculate before and after the start of summer. In the autumn, the temperature is not much different. You can inoculate before and after the beginning of autumn.
2. Inoculation method
The wolfberry cultivation is based on bacteria or fresh sorghum (sclerotia) as a "seed" for breeding. The strains were sterilized with Komatsu block tablets (plastics), and appropriate amount of culture medium was added. After the seedlings were cultured, the white exuberant mycelia grew in the bottles. Fresh taro breeding is the use of thin, tender red-brown taro, with a bamboo knife cut into pieces with a skin weight of 0.1 ~ 0.15kg as a breeding material for inoculation.
Before inoculation, open the cellar along the slope in the whole planting area. The cellar depth is 20cm, and the width is 40-50cm. The length depends on the length of the section. Slightly level the bottom of the pit, sprinkle with termite and mix well with the soil, and put Duanmu Shun into the pit. Put two paragraphs first. When inoculated with strains, first cut a new mouth with a width of 150cm10cm in the upper part of the two sections of wood, remove the piece of pine wood with mycelium in the bottle with a tweezers, and place it in the mouth of the new section between the sections of wood. , Cover with pine wood or pine leaves, and then put a section of wood (two sections of wood weight more than 20kg will not put the third section of wood), covering the earth 10 ~ 15cm. When inoculated with fresh squid slices, several saws were made at the upper end of the stalks. The fresh squatting pieces were affixed, gently rubbed and pressed by hand and covered with soil. The inoculation of tree shrews is to cut 2-3 new larvae on tree shrews, then inoculate the strains and fresh sorghum blocks at the new mouth of tree shrews, cover the pine wood pieces and pine leaves, and cover the soil 15~17cm. The face must be piled into a turtle shape.
Fourth, field management
1. Check the cellar to make up for the deficiency After 7 to 10 days after inoculation, white mycelia can be grown. At this time, the bacterial status in each cellar should be checked to make up for the shortage. 1 In the morning, when the dew is still dry, look at the planting sites. If the cellar section has long-lasting mycelium, then the soil on the pit is dry and there is no dew; if there is dew on the pit, it means that the section of wood does not have hyphae. 2 Dig the soil from the side of the pit and found that the lower section of the section has been grown with white mycelium. It smells like a scent and can be identified as a hyphae. If you find dead and non-microbial cellars, check them again every 7 to 10 days. If the second inspection still does not see the mycelia, the cellar can be removed from the other sections of the bacteria that have been added to the cell and transferred to the uninfected cellar. Or excavate all the wood that is not on the bacteria, dry the water, peel it off, and then connect the bacteria. 3 It should be noted that the sputum bacteria are not found on the wood surface for 1 month or so. At this point, most of the hyphae have grown into wood. One month after inoculation, no base hyphae were found, and it was mistaken for not cultivating bacteria and splitting the wood, causing undue loss.
2. After 7 to 10 days of inoculation, if termites are found, they should be sprayed immediately on the termites or ant roads for control.
3. After the sclerotia have formed sclerotia, if it is found that the ground should be soiled in time, the drainage should be noticed in the rainy season.
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.
3.Better protection with high titer and immune eff
icacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
