中文摘要：

通过对3种质地（沙壤、中壤和重壤）农田的土壤酶分析,得出沙壤土的酶活性低于中壤土和重壤土,重壤土的脲酶活性最高,沙壤土的转化酶活性最低,中壤土的磷酸酶活性最高。土壤酶活性随着农田土层深度（0～30 cm）的增加而降低。

英文摘要：

Soil enzyme activities of three textural（sandy loam,loam and clay soil） farmlands were analyzed,it showed that soil enzyme activities sandy loam of were significantly lower than loam and clay soil,Urease activity of clay soil was highest,Phosphatase activity of loam was highest.Soil enzyme activities reduced with the farmland soil depth（0-30cm） increased.
