秸秆还田不同处理方式对黑土微生物数量和土壤酶活性的影响
Effects of Different Way of Straw Returning on Microorganism Quantity and Soil Enzyme in Black Soil
摘要
Abstract
[ Objective ] In the field experiment, field test method was used to explore the effects of different way of straw returning on microor-ganism quantity and soil enzyme in black soil. [ Method] Dilution-plate method and quartering were used to analyze soil microorganism. Cata-lase and urease were measured using permanganate titration and Indigo atmosphere colorimetry. [ Result ] The quantity of soil bacteria, fungus and actinomycetes were increased significantly at the same application rate of the straw. The amplification was 61.1% , 111.3% and 113.5% respectively. Straw returning treatment and organic fertilizer treatment promoted the activity of the urease and catalase. The activity was signifi-cantly higher than that of the control. [ Conclusion] The research could provide the basis for the reclaimation of degraded black cultivated land and the selection of the models of straw returning.关键词
