Pre-seedling time should be at the temperature of cloudy tide in the middle and late February. All cuttings should be covered with wet and cold wheat straw near seedling stage, and it is strictly forbidden to resist air drying and strong light. Then build an arc-shaped plastic film with a large indoor space at the seedling stage, and fog every three to five days. It can be transplanted to the street in 50 days. It can only be obtained after 2-3 years, and it needs to be applied with base fertilizer. Generally 1 mu, apply 4000-5000 bases of organic fertilizer, ternary compound fertilizer 15-20KG, phosphorus and potassium fertilizer 10-20KG. Put it into the planting ditch, backfill the subsoil with a thickness of 20-30 cm, and mix the chemical fertilizer and the soil layer evenly.
Farming: Farming should be done first. First, the soil layer with a depth of 30 cm should be deeply loosened, and more ridges should be made according to the width of 1.2 m and 0.6 m, and the width of furrow between ridges should be 0.5~0.9 m, which is convenient for cultivation technology. Before ridging, apply organic fertilizer and compound fertilizer as base fertilizer at the bottom of ridge.
800 to 1 300 plants of Poria cocos should be planted in 1 mu, but 1300 plants must be planted in1mu. It is suggested to plant 800 plants 1 mu. The price per seedling of Pueraria lobata ranges from 1.5 to 3 yuan, and the average price per seedling is 2 yuan (the price varies according to the grade and variety of seedlings). Each method has its own advantages and disadvantages, and agricultural producers can choose according to their own standards. For example, in the past, there was no kudzu root planting and there was no resource for vine pre-seedling, so seeds were used for pre-seedling. But planting in the street is mostly a method. Ridge cultivation, 1 mu of land is evenly distributed, with a relative density of 600 ~ 800 plants.
