以燕麦“坝莜一号”为试验材料,设置不施褐煤腐植酸常规处理(C K),仅2011年施用腐植酸,连续2年、3年、4年施用腐植酸,以研究腐植酸对土壤微生物量及酶活性的影响,明确腐植酸对土壤生物学性状的改善效果。结果表明,连续多年施用腐植酸可增加燕麦苗期土壤微生物量碳、氮、磷含量,增强土壤蔗糖酶、脲酶、过氧化氢酶活性,有利于培肥土壤,促进土壤中有机物质的分解和转化以及土壤碳、氮等养分的循
Using oat “Dam No. 1” as test material, routine treatment of humic acid without applying brown coal (CK) was set, only humic acid was applied in 2011, humic acid was applied continuously for 2 years, 3 years and 4 years to study humic acid On soil microbial biomass and enzyme activity, to clarify the effect of humic acid on soil biological properties. The results showed that the application of humic acid for many years could increase the contents of soil microbial biomass carbon, nitrogen and phosphorus, increase the activities of soil invertase, urease and catalase, promote soil fertility and promote the decomposition of organic matter in soil Transformation and soil carbon, nitrogen and other nutrients
