塑料温室与大田内土壤动物群落特征的对比研究

目的】研究塑料温室与大田内土壤动物群落特征，为温室土壤生态系统的健康提供理论参考。方法]对塑料温室蔬菜地及其附近的大田采取定期采样，用手检法扣Tullgren漏斗法获取土壤动物，在实验室内分析鉴定。结果]通过4个月的实地调查及采样研究，共捕获土壤动物2453头，隶属于3门8纲11目。其中，弹尾目和蜱螨目为优势类群，分别占总捕获量的45．82％和25．72％；鞘翅目、等足目、寡毛纲、双翅目、腹足纲、直翅目和鞘翅目幼虫为常见种类，分别占全捕量的5．63％、5．01％、4．32％、3．10％、2．36％、2．32％和1．59％；其余类群为稀有种类。季节变动显示，塑料温室内5月份土壤动物数量最多，8月份最少；自然大田内是8月份土壤动物数量最多，5月份最少。各种多样性指数分析结果表明，群落复杂性指数（C）表征的土壤动物多样性比多样性指数（H）更能客观反映土壤动物分布的真实情况。结论]塑料温室蔬菜地中土壤动物的种类和数量比附近大田土壤中丰富，而且随着塑料温室使用时间的延长，其中的土壤动物数量越多，季节变动与大田中不一致。

Comparison of the Community Characteristics of Soil Animal in Plastic Greenhouse and Outside Field

Objective] The community characteristics of soil animal in between plastic greenhouse and outside field was researched for the theoretic reference for healthy system of soil ecology.Method] The samples,which were periodically taken in vegetable land in plastic greenhouse and near outside field,were analyzed and identified in Lab with manual measure and Tullgren method.Results] In the investigation and sampling for 4 months,a total of 2 453 soil animals were captured,belonging to 11 orders,8 classes and 3...
