摘要: 对沿江蔬菜地土壤动物群落的研究表明,18222个标本分隶于6门14纲29目72科,其中以弹尾目、螨目和线虫纲动物数量最多.同种青菜地土壤动物群落组成丰富性(S)、多样性、均匀性指数值以7月最大,12月最小;个体数、密度和优势性值以1月最大.在不同品种菜菜地,8月以青菜和韭菜S值最大,豇豆、毛豆次之,萝卜最小.但随着不同品种生长周期的变化,土壤动物群落结构也发生变化.肥力高的黑砂土,土壤动物群落各项指标高于沙洲菜地.

Abstract: In this paper, the soil animal community in vegetable plots along the Yangtze River is studied. 18222 specimens belonged to 6 phyla, 14 classes, 29 orders and 72 families are collected, among which, collembola, acarina and nematoda are dominant. In same plots, soil animal community has the maximum compositional richness, diversity and evenness index in July and the minimum ones in December, and its individual number, density and superiority index are the maximum in January. In August, the Svalue of Brassica chinensis and Allium tuberosum plots is the maximum, the second is Vigna sequipedalis and Clycine max plots, the minimum is Raphanus sativus plot. The structure of soil animal community is varied with the growth period of different varities of vegetables. Black sandy soil with high fertility level has a higher value of each index of soil animal community than sandbar.
