Abstract:

Reference materials were obtained by studying the diversity of soil animals for maintaining the health of greenhouse vegetables. Community structure of soil fauna in vegetable greenhouses was studied. The soil macrofauna were picked up by hands from different soil layers and the mesofauna were separated by tullgren method. Totally, 180 soil samples of 5 different greenhouses and 3442 individuals belonging to 13 orders were collected. The dominant groups were Parasiformes and Collembola, accounting for 87% of the total, the common groups were Lumbricida and Acariformes, and the rare groups the others. The results showed that the individual number of soil fauna varied with soil depth and most focus on the surface. Diversity index increased with evenness index, and decreased with dominance index.
