不同农业措施对草莓连作土壤微生物群落特征的影响
Effects of Different Agricultural Managements on Characteristics of Soil Microbial Community under Continuous Cropped Strawberry ( Fragaria ananassa Duchesne)
摘要
Abstract
[Objective] The objective of this study was to investigate the effects of different agricultural managements on soil microbial population, activity, functional diversity and soil enzyme activity in continuous mono-cropping field of strawberry. [Method] A field plot experiment was carried out to evaluate characteristics of soil microbial community by soil enzyme analysis, microbial cultivation and Biolog analysis. [ Result] The results showed that bacteria population proportion, the ration of bacteria to fungi, microorganism amount, AWCD, soil dehydrogen-ase activity,the Shannon, Simpson, and Mcintosh indices of soil microbial communities were obviously increased under strawberry-rice rotation, soil solarization with rice bran, and calcium cyanamide (CaCN2) treatments, in addition, soil urease activity was significantly increased under strawberry-rice rotation and soil solarization with rice bran treatment, when compared with no fertilization. When compared with conventional fertilization treatment, strawberry-rice rotation and soil solarization with rice bran both significantly increased AWCD and Mcintosh index of soil microbial communities, meanwhile respectively increased soil urease and dehydrogenase activity. PCA analyses suggested that carbon u-tilization of soil microbial communities under strawberry-rice rotation, soil solarization with rice bran, and calcium cyanamide treatment was obviously different from that of conventional fertilization and no fertilization treatment. [ Conclusion] Strawberry-rice rotation and soil solarization with rice bran were effective agricultural managements to control soil biological degradation under Continuous Cropped Strawberry.关键词
