Ecology of soil animal community in vegetable plots of suburbs along the Yangtze River in Anhui Province.

In this paper, the soil animal community in vegetable plots along the Yangtze River is studied. 18 222 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 S value 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.
