Abstract:

In order to study the promoting effect of soybean ‘Liaodou 20’ and the rhizosphere microbes by the new type of biological agent “Yifengshou”, we compared with brassinolide, compound fertilizer to research it by soybean pot experiment. In this paper, we investigated the soybean plant height, stem diameter and nodule several other growth indicators, yield components and rhizosphere bacteria, actinomycetes and fungi. Analyzed the data by statistical software SPSS 13.0. It could be drawn that “Yifengshou” promote the growth and yield of soybean significantly, increased soybean nodule number significantly, increased the population of rhizosphere bacteria, and it could bring about a striking effect that combined with fertilizer.
