How to grow soya bean root

Sophora root is a leguminous plant of the genus Phaseolus officinalis, also known as guangdou root, is a traditional Chinese medicine. The main part of medicine is its dry root and rhizome, which has the effect of clearing away heat and detoxification and relieving pain. the field is used to treat throat swelling, hepatitis, tumor and other diseases. At present, it is mainly distributed in Guangxi, Sichuan, Hunan and other places in China, and has a broad planting prospect. Today we are mainly going to learn the planting techniques of bean root. Let's read the introduction of the article.

1. Land selection and preparation

Soya bean root has the characteristics of shade, moisture, cold resistance, fear of stagnant water, and so on, and the soya bean root is mainly used as medicine, so the soil layer of the planting land had better be deep and loose. For example, you can talk about sandy loam, red soil and yellow soil. It is also important to note that it is not suitable to grow in acidic and alkaline soils, preferably neutral soils. Deep ploughing the land, fine the soil, properly improve the permeability of the soil, apply sufficient base fertilizer, base fertilizer can be used barnyard manure, soil manure, etc., and then make a border with a width of one meter and a height of 20 centimeters.

2. Cultivation techniques.

Soya bean root is generally planted in the way of seed propagation, and the time of sowing is usually in spring, but seed collection is best carried out around October every year. When sowing, we mainly use two ways, namely, direct seeding and seedling transplanting. During the live broadcast, we usually use hole sowing, so that the planting density can be reasonably guaranteed. The planting density generally maintains a row spacing of 40 cm and a plant spacing of 35 cm. If the seedlings are transplanted, the seeds can be scattered evenly on the seedbed, and the seedlings can be raised. After the seedlings emerge, they can be planted at a reasonable density.

3. Field management

After sowing bean root can emerge in about half a month. After the seedlings emerge, we need to observe the emergence of the seedlings and replenish the seedlings in time to ensure that the seedlings are uniform in the field. In the early stage of soya bean root growth, the growth rate is very slow, so it is easy to breed weeds in the field. In order to avoid nutrients being absorbed by weeds, it is necessary to carry out intertillage weeding. When weeding, a shallow hoe should be carried out so as not to hurt the root of the bean root. There is to keep the field soil moist, proper watering is conducive to the growth of the roots, but also to avoid stagnant water in the field, drainage in Rain Water more time, and the amount of watering can not be too large. Finally, it is necessary to do a good job in topdressing management to promote plant growth. Due to the strong nitrogen fixation of soya bean root, the demand for nitrogen fertilizer is small, but it also needs appropriate topdressing nitrogen fertilizer, followed by reasonable external fertilization, mainly compound fertilizer, phosphate fertilizer and micro-fertilizer. Finally, proper spraying of foliar fertilizer and growth hormone is beneficial to the growth of soya bean root.

4. Disease and pest control

The most common diseases of soya bean root are root rot and white silk disease, which are fungal diseases, which generally occur in the season of high temperature and humidity. Root rot is generally controlled by chlorothalonil, while white silk disease is controlled by carbendazim. Finally, there is the threat of insect pests, such as stem borer, bean pod borer, red spider, scale insects and so on, which can be controlled by corresponding pesticides.

The above is the introduction of the planting technology of soya bean root. I don't know how sure you are about the planting of soya bean root by reading the above. Can we achieve high yield and high quality? I look forward to hearing from you all.
