Abstract:
Taking soil of pressure sand watermelon→soybeans (W→S)，watermelon→peppers (W→P)，watermelon→oil sunflower (W→O) rotation cropping patterns and watermelon (control，CK) as research object，the effect of three different patterns of sand on the activity of crop rotation and microbial flora were studied.The results showed that compared with the control，the effect of three different rotation patterns on soil urease activity and alkaline phosphates activity were significantly enhanced crop rotation，soil invertase activity and catalase activity.W→P mode was significantly higher than the control，crop rotation patterns and other control to maintain balance;the total number of bacteria microbes under rotation mode increased in which bacteria，actinomycetes，bacteria and fungi ratio (B/F) were higher than control，the number of fungi was significantly lower than control;carbon source utilization by microbial community analysis showed rotation increased the microbial community carbon source utilization，enhanced the physiological activity of the microbial community.Description rational crop rotation on the extension of gravel-sand mulching life，restore and enhance the sand field force had a positive meaning，W→P crop rotation patterns was the more reasonable one.
