Abstract
To solve the problem of soil degradation with the increase of continuous cropping years in the solar greenhouse,changes of soil enzyme activities under five different agricultural treatments were studied.The results suggest that the soil enzyme activities are increased significantly under the rotation between vegetable chrysanthemum and tomato,and grafting tomato treatments.Soil urease,phosphatase and peroxidase activities are increased significantly as well under the calcium cyanamide treatment in summer.Cultivating welsh onion in summer,the soil enzyme activities in autumn are significantly higher than that in spring.The tomato yield coincides with activity variation of soil enzymes,this indicates that sucrase,urease,phosphatase,polyhenoloxidase and peroxidase can be used as sensitive biological indices for vegetable cultivation in greenhouse.In the region in which crop rotation is difficult,grafting cultivation can be used to increase soil enzyme activities,while,the rotation between vegetable chrysanthemum and tomato can play a positive role in maintaining soil enzyme activities and cultivation efficiency when the crop rotation is available.
