From late September to early October (1) Site preparation and land preparation: Choose sandy soil, black sand or alluvial loam where the terrain is high dry, soil permeability is good, sunlight is sufficient, soil is deep, and soil is loose. Pick a sunny day and plow till it is about 30 centimeters deep. Mushi fertilizer 1500 kg, cake fat about 100 kg, made into a width of 100-200 cm, a width of 33 cm, about 20 cm high turtle back. (2) Sowing: Before sowing, pour manure on the surface and soak it. After drying, dig it again, spread the seeds on the surface, cover with coke ash or waste fertilizer, 1000 kg per mu, keep the soil loose, conditional areas Can cover a layer of grass. From early February to mid-May (1) Fertilization: Do not apply or apply before spring and concentrate after spring. For the first time in February, Mushi 500 kg of manure was diluted three times before adding water; the second time in mid-March, 750 kg of manure was applied to Mushi and two times of water was added; the third time in April. In the middle of the year, Mu Shi applied 1,500 kilograms of barley fertilizer or 150 kilograms of cake fertilizer, spread it between plants or lines, and applied 25 kg of calcium phosphate, 750 kg of human feces or 10-15 kg of ammonium sulfate. Shi after the mud cover. (2) Weeding and weed control: In those days, the white hoe was not used for weeding and sparse seedlings, and the second year of February-March was used for thinning and pulling the grass. According to the planting distance of 13-16 cm, the weak seedlings, seedlings, diseased seedlings and "male seedlings" were removed (the seedlings were larger than normal, and the leaves stood upright at 45 degrees from the ground). After the closure of the line, weeding is no longer done. (3) Drainage: Zhejiang should drain water in time in this season and reduce the humidity in the field. (4) Pull out the moss-raising seedlings: From May, a few plants thrive and the bolting flowers bloom, affecting the growth of underground parts and should be removed in time. (5) Disease prevention and pest control: spot blotch and yellow swallowtail occur in the growing season and must be promptly controlled. From late July to early August (1) Harvest: First sunny weather, cut off the plants above the ground, use the gingivae to excavate the roots in turn, shake off the dirt, and quickly transport them to the drying yard for processing. (2) Processing: Cut off the remaining leaf base and remove the soil, cut the fibrous roots, and lay them on the drying ground according to the third, middle, and small scale respectively. Avoid drying on the concrete floor. Do not make rain, and retreat the booth indoors at night. In order to prevent mildew, sulfur can be used for fumigation. When smoked, they can be loaded separately according to their size and different wetness and dryness. In the middle of the big white dress, the middle and small white dresses are installed around, and the fresh clothes are placed on the bottom, and the sun is soft on the top. When installed, it is not compacted and it is helpful to pass smoke. After the installation, cover it with straw or sacks to reduce the smoke and walk away, and pay attention to human and animal safety. 500 kilograms of fresh white wolfberry needs 3.5-4 kg of sulphur. When smoking, sulfur must be added continuously, and it cannot be extinguished until smoked. After a night of smoke, the sample was spotted and examined. A small blade was used to cut the white peony into two pieces. The iodine was cut on the cut surface. If the blue color does not disappear, it means that it has not been smoked thoroughly and must continue to smoke sulfur. If the blue color disappears quickly, It has been shown that it can be extinguished and can be extinguished by fire until it is sunny again; in case of rain, it can be dried at a temperature of 60°C to prevent it from coking or drying. When dry, a few clicks can be crisp sound. (3) Seed-retaining: When harvesting, select the main root, thick as the mother finger, no bifurcation, robust and disease-free seeding. And cultivate in another place. Choose sunny, fertile soil, base fat and plowing, according to the spacing of 85-100 cm, 35 cm hole in the open hole species, a hole, a root tilt, do not bend, cover soil 4 cm, cover garbage, apply to people Dung, then soil 7 cm. Appeared in October when the weather turned cold. In November, we tilled and weeded once, applied sheep fat to the barn, and soiled 6 cm of soil next to the plant. In mid-February, we ploughed and weeded again, applied manure and phosphorus and potash fertilizers to promote the fullness of the seeds. In May, bolting was carried out, and plants were planted on the soil between the rows to raise furrows or plants. The seeds were gradually matured in July. When the seeds turned yellow-green, they could be harvested in batches in batches. And use the seeds in the middle of the inflorescence for seed collection
