摘　　要：为深入了解农田栽参土壤肥力状况,运用典型相关分析法对农田栽参土壤中主要养分含量与4种土壤酶活性的关系进行了分析。结果表明:农田栽参根区土壤中磷酸酶、蔗糖酶和过氧化氢酶活性与有机质、全氮、全磷、速效磷以及有效钾含量显著相关,其中磷酸酶影响土壤中磷的形态,蔗糖酶对土壤有机质转化和氮、磷、钾的含量及形态具有重要作用,过氧化氢酶能够加速土壤有机质分解转化。土壤中锌对上述酶活性有一定的促进作用;土壤脲酶活性影响土壤中碱解氮含量,土壤中铁和铜影响土壤中尿酶活性。结合其他养分因子,综合土壤酶活性指标可以作为评价农田栽参土壤肥力的一个生物活性指标。The correlation among some critical nutrient content and 4 soil enzyme activities of ginseng soil in farmland was studied by canonical correlation analysis to reveal its soil fertility. The results showed that soil enzymes, phosphatase activity, invertase activity and catalase activity had obvious correlation with content of organic matter, total nitrogen, total phosphorus, available phosphorus and available kalium while phosphatase activity affected phosphorus forms, and invertase activity played an important between transformation of organic matter and content and forms of nitrogen, phosphorus and kalium; Catalase activity accelerated decomposition transformation of organic matter. Only Zn content affected enzyme activity, promoting the activity of phosphatase, invertase, catalase to some extent. Soil urease activity affected content of alkaline nitrogen, nutrient Fe and Cu had an effect on urease activity. Integral soil enzyme factor can be used as a biological index of soil fertility, which, together with other growth factors, must be considered when ginseng soil in farmland is evaluated.
