Abstract: The study shows that in comparison with wetraising nursery,dryraising nursery had a greater size of soil aerobic azotobacter,cellulose decomposer,ammonifier,organic phosphorus decomposer and nitrite bacteria and a higher activity of soil protease,cellulase,phosphatase,urease and invertase,which is favorable to the conversion of soil matter and energy and the promotion of soil nutrient availability. It also shows that on dryraising nursery,rice seedlings had a more develped root system with a stronger ability of oxidation,and the roots exhibited a higher activity of amylase,nitrate reductase,ATPase and cell protective enzymes such as peroxidase,catalase and superoxide dismutase.
