本文对贵州东北低山丘陵山区茶园土壤螨类进行了调查研究,共获标本4253头,分隶4个亚目。其中隐气门类占个体总数的63%,分属38科。土壤螨类平均密度为1833.4ind/m2。土层(0-20cm)的螨类优势类群Schelorbates latpes(L.C.Koch),Rostrozetes ovulum Berlese占土层螨类27.43%。凋落物层(L层)的优势类群S.latipes(L.C.Koch)Galumna curvum Eeing,Oribatella meridionalis Berlese R.ovulum Berlese共占L层的42.73%。土壤螨类在L层和表土层(0-5cm)所占整个土壤螨类的87.73%。一年中以3-5月和9-12月份出现较多。土壤螨类栖息层次出现较强的表聚性,冬季也不减弱。
In this paper, soil mites from tea plantations in northeastern hilly mountainous areas of Guizhou Province were investigated. There were 4253 specimens of them, divided into 4 subfamilies. Which accounted for 63% of the total number of private subjects, belonging to 38 subjects. Soil mites average density of 1833.4ind / m2. Soil moss dominant species (0-20cm) Schelorbates latpes (L.C.Koch), Rostrozetes ovulum Berlese accounted for soil mites 27.43%. The dominant taxa of litter layer (L layer) S.latipes (L.C.Koch) Galumna curvum Eeing, Oribatella meridionalis Berlese R.ovulum Berlese accounted for 42.73% of the L layer. Soil mites accounted for 87.73% of the total soil mites in the L layer and topsoil (0-5cm). During the year, March-May and September-December appear more. Habitat soil mites showed a strong level of surface aggregation, nor is weakened in winter.
