| 摘 要： | 通过田间调查采样和室内分析测试的方法,对新疆南疆棉区不同连作年限的棉田土壤土壤酶活性特征进行了初步研究,结果表明:耕种后的棉田土壤的脲酶、过氧化氢酶、碱性磷酸酶、脱氢酶及转化酶活性都远高于未耕种荒地,连作棉田耕层土壤脲酶和碱性磷酸酶活性随种植年限的增加而逐渐增强,转化酶和脱氢酶活性随种植年限的增长先增加后而降低,过氧化氢酶活性变化不大.土壤剖面自上而下土壤酶活性除过氧化氢酶活性变化不大外,其它4种酶活性都呈现随土壤深度的增加而降低趋势,且土壤酶活性0～40 cm层均显著高于40～60 cm.

| Abstract: | Based on the field survey and lab test,the soil enzyme activities of different cotton cropping years' field in Southern Xinjiang were preliminarily studied.The results showed that the activities of urease,catalase,alkalescence phosphatase,dehydrogenase and invertase of soil enzyme activities were much higher than those of the uncultivated wasteland,the activities of urease and alkalescence phosphatase were increased along with the years of cotton continuous cropping,and the activities of invertase and dehyd... |
