Abstract:
We measuring the values of pH, the content of bacteria, fungi and actinomycetes in acidic black soil to explore the effects of organic-inorganic compound fertilizer on soybean rhizosphere. The results showed that the application of organic-inorganic compound fertilizers to the soil increased the number of soil bacteria, fungi and actinomycetes, in which the number of bacteria increased from 52×106 to 154×106·g-1, meanwhile the application of compound fertilizers resulted in the increasing of pH values (from 5.84 to 6.25) and activity of rhizobia. Besides, the addition of compound fertilizer enhanced the absorption of N, and K nutrients by soybean plant, which eventually led to the increase of soybean yield. These results indicate that the application of organic-inorganic compound fertilizer could improve the physical, chemical and nutrients conditions of the soil and this will lead to the increase of soybean yield ultimately.
