When transplanting, more soil and more water shall be taken to ensure the survival rate of transplanting. Second, deep and loose weeding Deepening and cultivating can not only eliminate weeds, but also prevent drought, protect soil, loosen soil, increase soil temperature, and promote the decomposition of soil nutrients, and can enhance the physiological activities of soybean roots to ensure normal growth and development of soybeans. Before the artificial or mechanical weeding, it is best to carry out deep furrows and the depth is generally 20 to 25 cm. For those who do not have deep loose conditions, they can also use a shovel to plow a plow. Three shovels are generally required.

Soya bean borer: When the insecticide rate reached 5% or more in the previous year, it reached the prevention and control index. It was made of poisonous sticks with 80% dichlorvos 1500-2000 ml per hectare, one row per 4 ridges, and one fumigation every 5 meters. Or spray pesticides with pyrethroids. 3.
