Transplanting soybean fertile seedlings in the soybean planting period due to disaster, such as continuous drought or rain can not be sown, transplanting by seedlings can shorten the vegetative growth time, ensure that the soybean field has sufficient growth period. Summer soybeans can be nursed 15 days before harvest. Soybean root-cutting and high-yield soybeans belong to the straight-rooted crops, with deeper soil, but less lateral roots. Timely cutting off the main root of soybean can promote the growth of soybean lateral roots, increase nutrient uptake and enhance the ability of rhizobia to fix nitrogen. The rooting should be carried out 10 to 11 days after sowing. The method is to cut the main root with a thin shovel at a depth of about 5 cm below the root of the bean seedlings. It is forbidden to displace the bean seedlings and damage the lateral roots. The cardiopulmonary soybean leggy growers have to take off the beans for leggy or late-maturing gluttonous soybeans, which promotes branching, dwarfs strong stalks, prevents lodging, allows more photosynthetic products to be imported into the flower buds, facilitates flowering and conservation, and increases yields. . Generally, it can increase production by more than 15%. Usually, the length of the main stem is 1-3 cm long at the early flowering stage or flowering stage.
