| 摘 要： | 桉树作为世界三大造林树种在我国南方很多地区广泛栽植,其经济价值和社会价值已经得到认同,但对其生态价值仍存在争议。对邓恩桉林地土壤酶活性与土壤养分性质和林木生长关系的研究表明：邓恩桉林地土壤磷酸酶、脲酶和蔗糖酶活性与营养元素全P和全N含量关系最大,即正效应较大,它们对N、P的转化具有重要作用。转化酶活性在一定程度上对土壤养分K、P和Mg含量有一定的负相关作用。说明邓恩桉林地土壤酶活性同土壤养分之间存在一定的相关性,并且有一定的专性特性。但“综合土壤酶因子”可作为邓恩桉林地土壤肥力的评价指标,还需对其适宜范围作进一步探讨。

| Abstract: | Eucalyptus as the world's three major tree species in our widely planted in many parts of the South,its economic value and social value has been widely recognized,but its ecological value is still in dispute.Through this experiment,Eucalyptus urophylla soil nutrient and soil enzyme activity and the nature of the relationship between tree growth studies have shown that: Eucalyptus urophylla soil phosphatase,urease and sucrose enzyme activities and nutrient elements in the entire P and N content of the whole ... |
