Efects of soaked seeds with phosphate-dissolving microorganisms on the growth and development and its nodule of soybean plant

Effects of soaked seeds with phosphate-dissolving microorganisms on the growth and development and its nodule of soybean plant were studied．The results show that the phosphate-dissolving microorganisms have evident effects on the early growth and nod ule of soybean plant；they can accelerate the processes of development，promote nod ulation，and increase the b．0 ca1 yield and N，P contents of soybean plant．Among all the treatments of phosphate-dissolving microorgarfisrns，Bacillus megatherium +Aspergillus sp．treatment has the best effect．
