草地土壤酸碱度直接影响以土壤为栖息地的甲螨种群的活动规律。本研究揭示了甲螨数量随土壤碱化程度而减少,呈负相关。有翅类甲螨与土壤酸碱度的关系较无翅类甲螨更为密切。土壤pH值为8.6—9.0时,无翅类甲螨与有翅类甲螨的数量比为1∶0.17,而甲螨种类比为1∶0.5。这表明,有翅类甲螨对生境选择性更高,而相对低等的无翅类甲螨则表现出对环境有更强的适应性。本研究还揭示了不同草场类型与甲螨数量变动关系,表现为高山>平原,山区的夏场>冬场>春秋场>割草场。农作物茬地甲螨数量明显偏少,仅为农区牧地的1/10。
Grassland soil pH directly affects the habitat of soil mites mites population activities. This study revealed that the amount of carboxime mite decreased with the degree of alkalization of soil, and was negatively correlated. The relationship between winged mite and soil pH is much closer than that of winged moth. When the soil pH was 8.6-9.0, the ratio of the number of winged mites to winged mites was 1: 0.17, and the ratio of mites to mites was 1: 0.5. This indicates that the winged mite mites are more selective for habitat, whereas the relatively lower mugworm mites exhibit greater environmental adaptability. The study also revealed the relationship between different grassland types and the amount of formamidorubidae. The results showed that there were alpine> plain, mountain summer> winter> spring and autumn> mowing. Occurrence of stubble moths significantly fewer crops, only 1/10 of the farmland.
