First, planting techniques of Anemarrhena asphodeloides
Seed propagation: Generally, Anemarrhena asphodeloides seeds are sown in April or June in spring 10- 1 1.5 kg/mu, and the germination rate is high in autumn sowing, and the seedlings are even. In the whole border, make the border with a row spacing of about 30-35cm and a depth of about 2cm. Then the seeds are evenly spread into the border, covered with soil, compacted and watered in time to keep the ground moist, and seedlings can emerge in about 20 days.
Root propagation: planting in spring is generally carried out after thawing and before germination. In the whole border, holes should be drilled at the spacing of about 15-20cm and the row spacing of about 30-35cm. The hole depth is about 7cm, and the amount of rhizome planted per mu is about 90 kg. Cut off the stems, leaves and fibrous roots left in the ground of Anemarrhena asphodeloides, then break the rhizome with bud head into 4-7 cm long segments, and put one segment in each hole. Raise your head to plant buds, cover the soil and water it in time. Water can be poured before planting, but the border should not be too wet to prevent root rot.
Second, the yield per mu of Anemarrhena asphodeloides.
The growth cycle of Anemarrhena asphodeloides is two years, and the yield of fresh products per mu is about 1500-2000 kg. First, remove the reed head and underground fibrous roots from the dug rhizome, scrape off the yellow fluff on the epidermis with a knife while it is fresh, and dry it in the sun to obtain Anemarrhena asphodeloides. Anemarrhena usually produces 400-500 kilograms of dry goods per mu, with a dry rate of 25%-30%.
Late management of Anemarrhena asphodeloides
After sowing, the soil should be kept moist and seedlings can emerge in about 20 days. When the seedlings grow to 3-4 cm, you can loosen the soil and weed. When the seedlings grow to 7- 10cm, the seedlings can be fixed according to the spacing of 15-20cm.
In the seedling stage, if the weather is dry, you need to water it in time. Because Anemarrhena asphodeloides planted with rhizome grows slowly in that year and needs a little water, it grows rapidly in the next year, which can increase the watering times. In case of high temperature and rainy season, water must be drained in time to prevent water accumulation.
When the seedlings grow to 15-20cm, 20 kg of calcium superphosphate and 10 kg of ammonium sulfate can be applied per mu, furrowing between rows, and burying the applied fertilizer in the soil to combine with scarification. If there is no need to leave seeds, nettles will be cut off in time.
