What are hybrid soybeans?

Hybrid soybeans are hybrid soybeans produced by crossing two inbred lines, like most of the corn hybrids we currently grow. Soybean hybrids generally increase yields by 15% to 20% over regular soybean varieties. At present, China has three hybrids through the validation of the northern region of spring soybean hybrid soybean 1 and hybrid soybean 2, the Yellow River and Huaihuai region of summer soybean with mixed excellent soybean 1. Now the hybrids are produced through the "three line" method, with a strong hybrid advantage.

Planting soybean hybrids need to pay attention to several issues: First, according to the local frost-free period and farming system to choose the appropriate maturity of the hybrid; second, soybean hybrids are generally more luxuriant growth and development, should be based on the soil conditions to determine the appropriate planting density, generally should be thinned out compared to the ordinary soybeans; third, if planted in the conditions of high soil fertility, high rainfall, should be taken to control the growth of the measures, such as the spraying of multi-purpose spraying before flowering. Such as spraying doxorubicin, eniconazole, triiodobenzoic acid and other growth inhibitors before flowering; fourth, soybean hybrid seeds can only be planted for one generation, the soybean produced by hybrids can only be used as commercial beans, and can not be used as seeds in the second year (season).
