1Environment: Choose a plot that is far away from the source of pollution, soil is loose, and meets the requirements. 2 Seedlings: Concentrate seedlings, cultivate strong seedlings, and improve the survival rate of transplants. Choosing thick and thick vines and cutting them into sections, each section has 2-3 stem sections for the stems, insert the seedbed, leave one stem section on the ground, keep the soil moist, and transplant it after germination. 3 Site preparation: 0.3 meters deep and 0.5 meters deep planting ditch, 1.2 meters from the ditch. The base fertilizer is mixed with the soil in the ditch and then back to the earth and the earthworms are 0.3 meters high. 4 Transplantation: transplanted in March, selected strong seedlings transplanted, planting specifications 0.41.2 meters, after planting poured roots set root water. 5 Fertilization: The main base fertilizer, supplemented by topdressing. Mushi rotted 2000 kg of farmyard manure, top-dressed with compound fertilizer, supplemented with leaching and infiltration of human fecal urine, every 15 days during the seedling stage, once a person's excrement, a total of 3-4 applications, to promote seedling growth. At the beginning of spraying, Mushi Sanyuan Compound Fertilizer is 30 kg. After that, the compound fertilizer is applied once every other month. Each time, the application amount is 30-50 kg per acre and the total application is 3-4 times, but it must be stopped one month before harvesting. Fertilizer. 6 field management: mainly grasp the fertilizer and water management, drought prevention, plugging seedlings, wipe buds weeding, cut off the excess roots, promote root swelling. When the seedlings are 0.5 meters high, 600-800 seedlings are planted in the mu-fence, combined with fertilization and weeding 1-2 times. Seedling height 1 meter buds topping, after the lateral bud 0.3 meters long topping, wipe buds once between 15 days. After the third dressing, the roots were dug in time, leaving 1-2 roots per plant as roots, and extra roots were cut off. 7 Pest control: Fructus Puerariae disease is mainly rust, controlled by triadimefon; insect pests mainly include seedlings of small earthworms that injure seedlings, medium-sized mites, noctuids, and spider mites. Control the use of trichlorfon or phoxim in small tigers; prevent spraying of beta-cypermethrin, kung fu, and thiophene, etc.; control the red spider's net spray with broom, and control pests once at the peak. The use of pesticides should be strictly in accordance with the standards of pollution-free vegetables. 8 Harvesting: The harvesting time can generally be harvested after October, but the harvesting quality is best in winter, and the nutrient is concentrated in the roots of the tuber, with less powder and more fiber. Harvesting can not damage the roots, to the net sediment and roots. For the sale of goods, the weight of each kilogram is more than 1 kilogram and the skin is smooth. When it fails to be sold in time after harvesting, it can be stored in sand and preserved in the ground. Each layer of powdered gaurd covers one layer of sand and is stored for 5 months.
