水保措施对油桃园土壤有机碳库及其组分的影响
Effects of Different Soil Conservation Measures on Soil Organic Carbon Pools in Nectarine Orchard
摘要
Abstract
Soil organic carbon(C)is greatly influenced by soil management practices. Here we compared the effects of different soil conser-vation measures on soil organic C fractions in nectarine orchard. There were three soil management practices:slope plus clean tillage(T1), terrace plus clean tillage(T2)and terrace plus sod culture(Arachis pintoi mulching)(T3). Soil organic C content in T3 orchard was 46.5%higher than in T1 and 15.3% higher than in T2. Compared with T1, the contents of particulate organic C(POC), light fraction of organic C (LFOC), dissolved organic C(DOC)and microbial biomass C(MBC)increased by 17.6%, 60.4%, 6.5%and 42.2% in T2 orchard, and 30.9%, 112.7%, 24.3% and 45.3% in T3 , respectively. Resistant organic C content in T3 was over 39% greater than in T1 or T2. Our results show that sod culture would increase soil organic C and improve soil fertility.关键词
