塔里木河上游典型绿洲连作棉田土壤酶活性与其理化性质的相关性分析
Enzymatic Activities and Related Physicochemical Properties in Soils of Continuous Cropping Cotton Fields Within a Typical Oasis in Upper Reaches of Tarim River
摘要
Abstract
Soil samples were collected at depth of 0--20 cm from a number of continuous cropping cotton fields across the Aler reclamation area of the upper reaches of the Tarim River. Five soil enzymatic activities and seven soil physieochemical properties were analyzed and their relationships were investigated using path analysis. The results showed that the enzymatic and physicochemical properties differed significantly between the continuous cropping cotton fields of various ages. Path analysis showed that soil enzymatic activities were mainly affected by total nitrogen in the soil and were significantly negatively correlated with soil pH value. The other factors such as soil organic matter, available P, available K and soil moisture indirectly influenced the enzymatic activities. Soil bulk density was found irrelevant with enzymatic activities.关键词
