大豆施根瘤菌剂可以增产,如果能适时适量补施化肥,则增产幅度会更大。磷肥底施:大豆根瘤固定的氮素和根系吸收的矿物质营养,只有在有磷素参加的情况下,才能输送到其它部位。给大豆底施磷肥,可以促进根系发育,根瘤增多,固定的氮素也就越多。施磷肥后,磷素不仅对大豆生长发育有促进作用,而且还能强化菌肥的作用。因此,大 Soybean Rhizobia agent can increase production, if adequate and timely replenishment of fertilizers, the rate of increase will be even greater. Phosphate application: Nodular fixed soybean root and root absorption of mineral nutrition, only in the case of phosphorus participation, can be transported to other parts. Phosphate fertilizer to the bottom of soybeans, can promote root development, nodules increased, the more fixed nitrogen also. Phosphate fertilizer, phosphorus not only promote the growth and development of soybean, but also to strengthen the role of microbial fertilizer. So big
