    摘要:

    为了明确有机种植对土壤动物的保护作用,在2013—2014年期间,对全国范围内的9个样点的有机种植和常规种植模式下土壤动物的多样性进行比较研究。在本次调查中,共发现土壤动物30目,其中大型土壤动物鉴定出20目,其中地表层19目,土壤层16目。总体而言,从数量上和类群上来看,有机种植模式下土壤动物(5.9×105 头/m2,7目)显著多于常规种植(4.3×105 头/m2,5目)。从多样性指数上来看,密度-类群指数(DG)有机显著优于常规,而香农多样性指数(H′)、均匀度指数(J)和优势度指数(C)在有机和常规之间没有显著差异。土壤动物数量与土壤肥力存在显著的相关关系。

    Abstract:

    In order to understand the protection of organic farming on soil fauna in China, soil fauna diversities were compared in 9 worldwide soils under organic and conventional cultivation during the period of 2013—2014. A total of 30 orders were found in the survey, among them, a total of 20 orders macro-fauna were observed, in which 19 orders were observed aboveground and 16 orders belowground. Both the total abundance (5.9×105 individuals per square meter) and groups (7 orders) in organic farming were significantly higher than those [4.3×105 individuals per square meter, 5 orders] in conventional farming. From the aspect of diversity ecological indices, density-groups index (DG) of soil fauna were significantly higher in organic farming, but no significant difference was found in other ecological indices between organic and conventional farming. Significant correlations were observed between soil fertility and soil fauna numbers.
