Abstract The main nutrition contents,enzymie activities,qualification of aquaous steady globs and salt accumulation in continuous cropping plastic greenhouse were investigaled. Results showed that the amount of main soil nutrients,the activities of soil urease,nutral phosphatase,acid phosphatase and 2~0.25mm aquaous steady globs increased,and the soil property of physical structure was improved. However,the chemical property of soil became worse and the salt was accumulated.
