First, nursery selection: Select a flat sandy soil cultivation, requiring good drainage and irrigation, groundwater level should not be too high. Do not grow on clay. Soil preparation and fertilization: Deep-turning land in autumn or spring can be combined with 3-5 tons of mature farmyard fertilizer. Before sowing, the best soil disinfection, according to the width of 1.3-1.5 meters, 10-20 meters long seedbed. Sowing: The seed germination rate of ephedra is the highest at 15°C-25°C. The best sowing time can be selected according to the climate characteristics of different regions. Sowing is generally good from May to June, and it is easy to fall before freezing. Carbendazim, chlorothalonil or copper sulphate should be used to soak seed before sowing. In general, the sowing rate for the mu is 10-15 kg. Before the sowing, firstly irrigate the water, then spread the seeds evenly on the seedbed and finally cover the fine sand of 0.5-1 cm. Seedling can be watered with a micro-watering pot to keep the seedbed moist. Seedling management: After the seedlings are in full bloom, weeds must be removed in time to loosen soil and maintain soil moisture. When the ephedra seedlings grow to 4-5 cm, the number of watering can be appropriately reduced. If there is water accumulation, it should be eliminated in time. Pay attention to the control of blight and locust infestation. According to the seedlings in the vigorous growth stage followed by 2-4 compound fertilizers, the compound fertilizer should be dominated by nitrogen fertilizer. Second, transplanting In general, the ephedra seedlings in the fall of the year or the spring of the second year out of the nursery, transplants should do the following work. Selection of land: The neutral sandy loam soil with good terrain and good drainage and irrigation conditions was selected as a transplanting site. Soil preparation and fertilization: deep-turning land in autumn or spring, Mushi 1-2 tons of farmyard fertilizer. Before transplanting, open a 20 cm deep ditch with a certain spacing. Transplant: Transplant in spring or autumn. When raising the seedlings, care should be taken to avoid rooting, and grading and packing work should be done to ensure water retention during transportation. In general, 1-1.2 million plants are planted per acre, and planting spacing is 20-40 cm. When planting, plant the seedlings at a spacing of 20-25 cm, and cover the depth of soil with roots and stems buried in the soil 2-3 cm. It is advisable to keep the roots stretched, and then water the seedlings. Third, the field management of water and fertilizer management: timely watering in the seedling period, growth can flourish nitrogen, phosphorus, potassium fertilizer 2-4 times. Weeding and weeding: 3-5 times a year of loose soil, combined with loose soil to remove weeds 3-5 times. As ephedra is a strong positive plant, the growth of weeds must be eliminated. Pest control: In the early spring and in the high temperature and high humidity seasons, the occurrence of pests and diseases must be strictly controlled. Various pesticides can be used for prevention and control. Ephedra after transplanting can generally be harvested for 2-3 years. If properly managed, the yield per mu can reach 1000-2000 kg.
