摘要

By using red soil and late rice Wufengyou T025 as the tested materials, the influences of straw returning with a microbial agent on the quantity of microorganisms and enzyme activity in rhizosphere soil in fields were studied, and soil productivity was tested with yield and agricultural traits of late rice. The results showed that straw returning with the microbial agent could significantly improve the quantity of bacteria, fungi and actinomyces in soil, enhance the activity of sucrase, urease, catalase and cellulase, and improve the number of grains per spike, setting percentage,thousand seed weight and yield of late rice. The combination of rice straw returning and the microbial agent has a good prospect of application.
