What are the requirements for soil conditions of soybeans?
Soybean growth and development on the soil requirements are not strict, in addition to swamp, saline-alkali land, deep soil layer, rich in organic matter, good drainage irrigation, strong water retention, pH6.8-7.5 soil is the most suitable for planting soybeans, red and yellow soil mountain planting soybeans, as long as attention to fertilizer management can also obtain yield.

Sowing technique of soybean by stages
Sowing by stages can stagger the corn harvest period of fresh soybeans, which is beneficial to prolong the supply period, expand market capacity, avoid a large number of centralized listing, resulting in excessive supply, large quantity and low price, and increase production without increasing income. and can ease the labor contradiction in the busy agricultural season to a certain extent. To do a good job of sowing by stages, the key is to achieve the following four points. 1, look at the local market situation to grow fresh soybeans and corn, high yield is not the goal, the important thing is high efficiency. & ldquo; goods are precious because they are scarce & the market price of rdquo;, is always the same as that of

Soybean can produce high yield by cutting root and picking heart.
The main results are as follows: 1. Soybean root-cutting and coring high-yield cultivation method of soybean direct seeding, row spacing 50 cm, coring 8 ~ 9 days after sowing, and root cutting on 10 ~ 11 days. When breaking the root, use a thin shovel to shovel off the main root at a depth of about 5 cm underground. The shovel is inserted obliquely and pulled out in situ to avoid shifting the bean seedling and injuring the lateral root. The position of the broken root should be about 2.5 cm under the stem of the bean seedling, too deep and too shallow can not achieve the desired purpose, or even cause dead seedlings. Second, several problems that should be paid attention to. 1. Density soybean density depends on variety and cultivation conditions.
