How to cultivate Achyranthes bidentata?

How to cultivate Achyranthes bidentata? Please introduce Achyranthes bidentata (Achyranthes bidentata) as a perennial medicinal herb of Amaranthaceae, which is also known as Achyranthes bidentata (Sichuan), Achyranthes bidentata (Huaiqing, Henan) and so on. The cultivation of Achyranthes bidentata can be carried out with reference to the following methods: growth environment: 1. Requirements for environmental conditions. Achyranthes bidentata is a deep-rooted plant, like warm climate conditions, suitable for growing in dry, sunny, well-drained sandy loam, requiring deep soil layer, loose and fertile soil, conducive to root growth; sticky tangerine soil, waterlogged saline-alkali land is not suitable for planting. Intolerant of severe cold, the temperature dropped to-17 ℃, and most of the plants died from freezing. 2. Characteristics of production and development. Due to the short growth period and poor quality, the germination rate is only 10-20%, and the yield of the flower root is reduced, and the quality is degraded. Biennial seeds are called 'beating seeds', and their germination rate and growth are better. Biennial 'beating seeds' are mostly used in production. Generally, the seeds of Achyranthes bidentata are 21-25 ℃, and the humidity is suitable for medical teaching. Sow seeds under the original parts of the breeding net, and all the seedlings can be produced in 7-10 days. During the growth period, sufficient water is preferred in the seedling stage and autumn, but not too much water in the middle stage, and the root growth is exuberant in the flowering stage and after anthesis, so management should be strengthened to promote root growth. Cultivation and management methods: land selection and preparation: Achyranthes bidentata has strong adaptability and can be planted in general soil, but it can not be planted in saline-alkali land, heavy clay land, waterlogged land and soil layer book. The sandy loam with deep soil layer, sunny dry and loose and fertile soil is the most suitable (deep ploughing, soil preparation and bed cultivation are all carried out according to the requirements of planting Platycodon grandiflorum). It is best to apply fertilizer in autumn when there are conditions. After the harvest of the previous crop, apply high-quality farm manure 4000kg, monoammonium phosphate 8-10kg, long-acting ammonium bicarbonate at 50-60kg, potassium sulfate 5-7kg, before turning deeply, evenly spread the field surface, then turn 30-40cm deeply, level and rake fine, and sow seeds in spring next year. Planting treatment: 7-10 days before sowing, the seeds were selected by the wind and insolated for 2-3 days, and the germination experiment was carried out. The bud rate was more than 80%, and the sowing rate was only 2-2.5kg per mu. The day before sowing, soak the seeds in 20C warm water for 12 hours, remove them to dry, mix fine sand or plant ash at a ratio of 1:30, and then sow. Suitable sowing time: the suitable sowing time is the key to the cultivation and production of Achyranthes bidentata. Early, the ground does not grow, the root is easy to be divided into medical teaching. Yuwang original fork and Lignification, and easy to early flowering to consume nutrients, affecting the yield and quality. If it is too late, the growth period will be shortened, the growth will be stunted, and the yield will decrease. Niuyingzi area in Chifeng is suitable for sowing from late May to mid-June. There are also replanting fields, but no later than the end of June at the latest. Sowing method: 1. Broadcast on the Internet. The row spacing is 15-20cm, the ditch depth is 2-3cm, and the thickness of soil cover is about 1.5cm. Tread lightly with your foot after sowing. At the same time, in the field without autumn fertilizer, 8-10kg of monoammonium phosphate and 5-7kg of potassium sulfate were applied per mu, and the seeds were stratified and necrotized, and the soil medicine was first fertilized. Sow seeds after the original Yu net. two。 Interplanting. In order to improve the land utilization rate, wheat can be planted between rows from late May to early June, and can be harvested in the same year. 3. Replanting. When Codonopsis pilosula, Platycodon grandiflorum and other drug fields are incomplete, Achyranthes bidentata can be replanted to increase the income of the year. Daily management: 1. Ploughing and loosening soil: generally, seedlings can emerge 7-10 days after sowing. When seedling height is 2-3cm, ploughing and loosening soil is carried out with hand scraping hoe, and weeding of vegetable seedlings is carried out at the same time. 2. Seedling fixing room: seedling height 5cm was used to determine seedlings and pull out weeds in the field. 3. Appropriate watering: the border surface should be kept moist before emergence and seedling stage, and should be watered in time in case of drought, in order to keep the topsoil dry and loose, and the lower soil should be moist and grow downward. After the middle of August, the main root basically does not grow underground, so the amount of irrigation should be increased in order to thicken the main root and increase the yield. 4. Topdressing in time: topdressing 1-2 times during the growth of Achyranthes bidentata, mainly phosphorus and potassium fertilizer, general medical education. When the plant growth 25cm is high, topdressing ammonium phosphate 4-5kg per mu, urea 10kg, phosphate fertilizer 2-3kg. 5, topping to promote root: the production day enters August, the plant growth is too prosperous, and after leaving 30-40cm high plants, the upper part is cut with a sickle, which can reduce nutrient consumption and promote taproot thickening.
