摘  要:
对供试红壤的基本化学性质、微生物量以及酶活性进行分析.结果表明,红壤脲酶、蔗糖酶、磷酸酶及过氧化氢酶与土壤有机碳、全氮及全磷显著相关或极显著相关,这些酶活性反映了红壤肥力水平的差异.土壤酶活性聚类分析结果与根据土壤化学、生物学性质所得结果基本相似.酶活性可用于评价红壤肥力质量.新鲜土样的酶活性不仅高于风干土样,且与土壤肥力质量联系更为密切.

摘  要:
Correlation and cluster analyses on the enzyme activities and chemical-biological properties of eight red soils showed that soil urease,invertase,phosphatase and catalase activities correlated significantly with soil organic carbon,total nitrogen and total phosphorous.Similar results of soil fertility evaluation were obtained by using soil enzyme activities and by using soil chemical-biological properties,indicating that soil enzyme activity could be used as an index of evaluating red soil fertility.The enzyme activities of fresh soil were generally greater than those of air-dried sample,and more closely correlated with soil fertility.
