Analysis on the role of rhizobia in soybean planting
Rhizobium soybean is a live microbial preparation. The rhizobia in the root nodules and the legumes are mutually beneficial: the organic matter produced by the legumes through photosynthesis is partly supplied to the rhizobia; the ammonia produced by the rhizobia through biological nitrogen fixation is supplied to the legumes plant. , it fixes free nitrogen in the air to supply soybeans to meet soybean demand for nitrogen. It is a good measure to increase soybean yield, save fertilizer and reduce pollution, and has been valued by researchers around the world. First, the role of rhizobia 1. Nitrogen fixation Soybean rhizobia uses the products of soybean photosynthesis as energy, and converts nitrogen in the air into nutrients required for soybean growth and development. Rhizobium and soybean have a symbiotic nitrogen fixation relationship. At the beginning, soybean rhizobia fixed little nitrogen, until flowering to drum. The initial stage of grain is the peak of nitrogen fixation by so...
