免耕条件下不同有机物料还田对土壤有机碳及微生物量碳含量的影响
Effects of Organic Fertilization Returning on Organic Carbon and Activated Carbon Components under Conservation Tillage
摘要
Abstract
The field experiment took nylon bag technique and provided with corn stalks,manure,compost and other organic materials in different quantities to research soil organic carbon and microbial biomass carbon content in Dingxi city . The result shows that the three kinds of organic material can improve the content of soil organic carbon, microbial biomass carbon with no tillage, under the condition of high organic carbon content changes from high to low in turn for straw, manure, pig manure; Under middle and low levels from high to low in turn to compost, straw, pig manure . Soil microbial biomass carbon content in organic material, high volume levels increase trend in the form of compost, straw, manure, low levels of manure, pig manure and straw .关键词
