稻草还田配施催腐菌剂对晚稻根际土壤微生物与酶活性及产量的影响
Effects of Straw-Returning Using Agent on Microbe and Enzyme Activity in Rhizosphere Soils and Yield of Late Rice
摘要
Abstract
Straw-returning isn't only beneficial to the soil sustainability, but aslo influences on the soil productivity. Using the red soils and late rice Wufengyou T025 as the tested materials, we studied the influence of straw returning with straw decomposition agent on microbe, enzyme in rhizosphere soils and the late rice yield in field experiments. The microbial quantity, enzyme activity in rhizosphere soils were investigated with the different ways of straw return, and the soil productivity was examined with yield and agricultural traits of late rice. The results showed that straw returning with microbial agent could significantly improve the quantity of bacteria, fungi and actinomyces in soil, enhance the activity of sucrase, urease, catalase and cellulase, improve the grain numbers per spike and the 1 000 grain weight and yield. The straw returning with microbial has good application prospects.关键词
