摘要
本文是根据济宁农田土壤动物调查结果而完成的。秸秆焚烧使土壤甲螨的类群和数量均有不同程度的减少,对玉米样地的影响比对大豆样地更为明显;土壤甲螨的季节变化是非常明显的,与对照区相比,秸秆焚烧会使群落数量高峰期明显后延;秸秆焚烧使群落的多样性降低。
The author reports the study results on soil animals in the farmland environment in Jining district. Burning straw has make both their groups and their amount of soil Oribatida reduce to a greater or lesser degree and the influence of crop straw burning was even stronger on corn field than on soybean field. The seasonal variations in soil Oribatida communities are also very obvious. Comparing with the contrast field , straw burning will obviously delay the peak of the community number. Straw burning also sort of lowered the diversity index.
