Achyranthes bidentata seeds are oblong, yellow-brown, with a flowering period from July to September and a fruiting period from September to October. So what are the common varieties of Achyranthes bidentata seeds? What are the seedling-raising methods? Let's find out together.
What are the common varieties of Achyranthes bidentata seeds?
The common varieties are Sichuan Achyranthes bidentata, Huai Achyranthes bidentata and soil Achyranthes bidentata. Sichuan Achyranthes bidentata is produced in Sichuan and other places; Huai Achyranthes bidentata is produced in Wenxian, Wuzhi, Boai, Qinyang and other places in Henan; while soil Achyranthes bidentata is a wild variety.
Achyranthes bidentata is a deep-rooted crop with strong adaptability and is not strict about the previous crop. It can be planted in general soil, but saline-alkali land, heavy clay land, waterlogged lowland and land with a thin soil layer cannot be selected for planting. Seed propagation is used in production, and the usual seeding rate is about 4 jin per mu.
What are the seedling-raising methods?
1. Soil selection
Achyranthes bidentata has no strict requirements for soil. Except for clay and saline-alkali soil, general soil can be used for planting, but for high yield, in production, sandy loam and yellow soil that are warm and humid in climate, loose and fertile, and well-drained are generally selected.
2. Land preparation and fertilization
The roots of Achyranthes bidentata reach a depth of 0.6-1 m, so deep plowing of 0.5-0.7 m is required. Before plowing, apply 2500-4000 kg of compost or barnyard manure and 40-50 kg of superphosphate per mu. Before planting, mix it evenly, pile and compost it for several days, then spread it evenly on the topsoil, and then plow it into the soil as base fertilizer.
3. Sowing and seedling raising
The germination rate of Achyranthes bidentata seeds is generally 80%, the suitable temperature is 21-23°C, and with sufficient humidity, seedlings can emerge 4-5 days after sowing. Sowing is generally done in early July. Before sowing, soak the seeds in warm water at 20°C for 12 hours, take them out and dry them, then mix them evenly with burnt soil ash and human and livestock manure water and broadcast them on the seedbed surface. After sowing, gently rake the soil surface with a four-tooth rake so that the seeds sink into the soil, then sprinkle and cover a layer of fine soil about 1-1.5 cm thick. Finally, sprinkle and cover a thin layer of rice husks on the seedbed surface to facilitate seedling emergence.
4. Field management
During the seedling stage, watering must be completed 1-2 times. In September, Achyranthes bidentata is in a period of rapid root growth. During this period, if there is a drought, appropriate irrigation can be given to ensure good root development. However, in the rainy season, attention should be paid to timely drainage to avoid root rot. Before the harvest of Achyranthes bidentata, an appropriate amount of irrigation can be given once, which is beneficial for digging out the roots.
The above is an introduction to the varieties and seedling-raising methods of Achyranthes bidentata seeds, and we hope it can have some reference value for everyone.
