Abstract:
Taking 7 years continuous cropping test field of cucumber as research object,illustrate the cucumber-corn rotation preventing soil of continuous cropping in greenhouse,the experiment was set different density and different growth period for the followed corn,and the soil physical and chemical properties,soil enzyme activity and soil microbial populations were studied.The results showed that the optimum effect was the density of 4 000 plants/667m2,mature pattern of corn growth.Compared with leisure processing,the number of bulk density and EC were down,and the content of soil organic matter,available nitrogen,available phosphorus and available potassium were lower,but pH was up,and meanwhile,rotation enhanced the activities of soil urease,catalase,and declined invertase and phosphatase;the components of soil microbial communities were changed,which were manifested in the increase of bacteria and actinomycetes and the decrease of fungi.Crop rotation could significantly improve the properties of soil.
