对不同耕作方式土壤的土壤动物种类组成的影响进行了研究,共分离鉴定土壤动物2140只,隶属2门8纲18目,其中蔬菜生产基地分离797只动物隶属1门4纲11目,村民自留菜地分离1343只动物,隶属2门8纲14目。村民自留菜地土壤动物结构复杂,优势类群和常见类群数高于蔬菜生产基地,Shannon-Wienner多样性指数H’、Pielou均匀度指数E和优势度C高。说明传统施用有机肥、不喷洒农药和化肥的耕作方式更加有利于土壤动物的生长繁殖,农药和化肥比土壤肥力对土壤动物的影响更大。
The effects of different tillage soil types on soil animal species composition were studied. 2140 soil animal species were isolated and identified, belonging to 2 orders, 8 classes and 18 orders. Among them, 797 animals belonging to 1 vegetable field, 4 classes and 11 orders, 1343 animals were left in the vegetable garden, belonging to 2 orders, 8 orders and 14 orders. The structure of soil fauna in villagers ’own vegetable garden is complex, the dominant groups and common groups are higher than the vegetable production bases, and Shannon-Wienner diversity index H’, Pielou evenness index E and dominance C are high. It shows that the traditional farming methods of organic fertilizer, non-spraying pesticide and chemical fertilizer are more conducive to the growth and reproduction of soil animals. Pesticides and fertilizers have more influence on soil fauna than soil fertility.
