| 摘 要： | 本文对大豆连作条件下土壤ｐＨ变化对土壤酶活性的影响进行了初步研究，研究结果指出，大豆连作土壤ｐＨ变化与土壤脲酶、转化酶、过氧化氢酶、磷酸酶的酶活性之间存在着显著的正相关，表明大豆连作土壤ｐＨ的变化是影响土壤酶活性的主要因素，也是连作大豆对不良环境的交叉适应。

SOIL pH OF CONTINUOUS CROPPING SOYBEAN AND SOIL ENZYME ACTIVITY |
| |
| Abstract: | Effect of dynamic characteristics of soil pH under continuous soybean cropping on soil enzymes activities were studies. The results indicated that between the dynamic characteristics of soil pH and four kinds of enzymes(i.g. urease, phosphorylase, catalase and transferrase) were evidently positivein in correlation. We suggested that the dynamic characteristics of soil pH under continuous soybean cropping are main factor for influencing soil enzymes activities. At the same time, it is also an intersect adaptation of soybean to continuous cropping on harmful soil environment. |
