摘要
描述了在速效钾缺乏的土壤上 ,施用钾细菌制剂对水稻生长发育的促进作用。通过钾细菌促进土壤矿物释放一定量的速效钾 ,抑制水稻前期无效分蘖的生长 ,促进后期植株上部功能叶片生长 ,提高植株光合效率及水稻对土壤中其它养分的利用率 ,协调养分平衡 ,导致水稻最终增产增收。
Beneficial effects of Bacillus mucilaginosus preparation on the growth of rice plant in the potassium deficient soil are described in the paper. It is indicated that stimulating the early rice growth of stem and tiller and decreasing the ineffective tillers and later functional leaf mainly through increasing the release of the available potassium in the potassium-deficient soil led to high effective light synthesis, high utilization rate of soil nutrition, coordination of soil nutrition equilibrium, finally the rise of yield of rice.
