摘要
对中国农业大学实验站农田土壤螨群落变化与环境因素的关系研究结果表明,土壤螨种类与数量随土壤养分的增加而增加,随土壤容重和pH值的增大而减少;长期施用EM堆肥,土壤孔隙多,通气性好,土壤耕层增厚,有机质含量提高,土壤螨种类与数量最多。
The relationship between community of soil mites and environmental factors was studied in farmland of experement station. The species and quantity of soil mites was increased with increasing soil nutrients, but decreased with increasing soil bulk density and pH. Soil porosity and aeration got well , furrow layer incrassated>the organic matter increased and there were more species and quantity of soil mites in the plots which have used EM compost for a long time.
