摘要
对山东青州蔬菜种植区内栽培年限分别为1、3、5、7、9年和已废弃1、3年的日光温室及农田中土壤动物进行了为期一年的调查,结果表明,日光温室长期应用有使动物类群数减少、密度降低、多样性指数变小的趋势,温室废弃3年后,土壤动物群落结构可自行调整恢复。
The effects of plastic greenhouse on the community of soil animals in Qingzhou district were studied in 5 plastic greenhouses used for 1 year and 3, 5, 7,9 years respectively, 2 plastic greenhouses abandoned for 1 year and 3 years respectively and the farmland. The results showed that the greenhouse could cause the decrease in the amount, density and diversity index of soil animals, but this diversification could be recovered normally after the greenhouse was abandoned for 3 years.
