How to grow the latest soya bean root

Sophora tonkinensis is a kind of traditional Chinese medicine, which belongs to the genus sophora, also known as phaseolus root. The main medicinal site is its dry roots and rhizomes, which have the effects of clearing heat and detoxifying and relieving pain. It is used to treat sore throat, hepatitis, tumor and other diseases. At present, it is mainly distributed in Guangxi, Sichuan, Hunan and other places in China, and has broad planting prospects. Today, we mainly learn the planting technology of subprostrate sophora root. Let's read the content introduction in this article together.

1. Land selection and preparation

Sophora tonkinensis has the characteristics of liking shade, liking moisture, not cold tolerance, afraid of ponding, etc., and Sophora tonkinensis is mainly used as medicine by its roots, so the soil layer of planting land should be deep and loose. For example, sandy loam, red soil, yellow soil can be. Also note that it is not suitable for growth in acidic soil and alkaline soil, preferably neutral soil. Deep ploughing of the land, the soil will be fine, appropriate to improve the permeability of the soil, apply sufficient base fertilizer, base fertilizer can be used manure, soil miscellaneous fertilizer, and then made into a width of one meter, 20 centimeters of the plot.

2. Cultivation techniques

Sophora tonkinensis is generally planted by seed reproduction, sowing time is generally spring, but seed collection is best carried out around October every year. When sowing, we mainly use two methods, namely direct seeding and seedling transplanting. We generally use the method of hole seeding when direct seeding, so that we can reasonably ensure the planting density. The planting density generally maintains a row spacing of 40 cm and a plant spacing of 35 cm. Seedling transplanting, then you can directly spread the seeds evenly on the seedbed, seedlings, such as seedlings after emergence, and then according to a reasonable density for planting.

3. Field management

After sowing, Sophora tonkinensis can emerge in about half a month. After the seedlings emerge, it is necessary to observe the emergence of seedlings and supplement seedlings in time to ensure that the seedlings are homogeneous in the field. In the early stage of growth, the growth speed of Sophora tonkinensis is very slow, so weeds are easy to breed in the field. In order to avoid nutrients being absorbed by weeds, it is necessary to carry out intertillage and weeding. When weeding, shallow hoe should be carried out to avoid damaging the roots of sophora root. There is also to keep the soil wet in the field, proper watering, conducive to the growth of roots, but also to avoid water in the field, drainage when there is more rain, there is also the amount of watering can not be too large. Finally, it is necessary to do a good job of topdressing management to promote the growth of plants. Due to the strong nitrogen fixation of Sophora tonkinensis, the demand for nitrogen fertilizer is not large, but appropriate topdressing nitrogen fertilizer is also needed. Secondly, reasonable fertilization outside the root is mainly based on compound fertilizer, phosphorus fertilizer and trace fertilizer. Finally, proper foliar fertilizer and growth hormone spraying are beneficial to the growth of Sophora tonkinensis.

4. Disease and pest control

The most common diseases of Sophora tonkinensis root are root rot and white silk disease, which are fungal diseases, generally occurring in high temperature and humidity seasons. Root rot is generally controlled by chlorothalonil, while white silk disease is controlled by carbendazim. Finally, there is the threat of pests, such as stem borers, pod borers, red spiders, scale insects, etc., which can be controlled with corresponding insecticides.

The above is the introduction of the planting technology of Sophora tonkinensis. I don't know how much you can grasp the planting of Sophora tonkinensis through reading the above. Can we achieve high yield and high quality? Looking forward to good news from everyone.
