Abstract:
Continuous and one year intermittent cropping problem is one of the primary reasons to the reduction of output and decline of quality in soybean, whereas fertilizing fitting antimicrobial agent can improve rhizosphere microbe and prompt soybean growth. Consequently, it can alleviate or even eliminate the side-effect of continuous and one year intermittent cropping. This paper compared the continuous and one year intermittent cropping soybean which treated by antimicrobial agent with the normal treatment and separately measured nitrogen assimilation quantity and rhizosphere microbe in different growth period. Through two years tests it showed that the constitutes of micro organisms on soybean rhizosphere changed significantly when the screening antimicrobial agent was applied at planting. The number of bacteria and actinomyces increased, at the same time the number of fungi decreased. Thus improved the condition of nodding and nitrogen fixing,prompted soybean growth,enhanced the assimilation of nitrogen on soybean seed,and alleviated the nitrogen assimilation obstade of the contionuous and one year intermittent cropping soybean.
