| 摘 要： | 对不同施肥条件下农田中的土壤螨进行调查，结果表明：（1）EM堆肥区土壤有机层加深，土壤螨垂直分布下限下移；（2）施用EM堆肥土壤螨数量多，物种丰富，分布均匀，长期施用EM堆肥可以形成多层次的食物网络，传统堆肥区土壤螨数量和种类较化肥区多，单纯施用化肥的农田，土壤螨数量和种类呈减少趋势，群落结构稳定性差，土壤生物间的联系向单一化方向发展。 |

| Abstract: | Community structure of soil mites in the farmland treated with three different fertilizers was studied in Qu zhou experiment station, China Agricultural University from April to September 1997. Recent years, inputting more and more chemical fertilizers and pesticides into farmland has disturbed sustainable soil utilization. Alternative methods are imperative to be searched. Effective Microorganisms (EM) compost is a compound fertilizer with many microorganisms. What will happen by using EM compost to ecolog... |
