Abstract

The effects of shading on soil microorganism characteristics, soil nutrient and enzyme activity changes in matcha tea garden of Zhejiang province were analyzed. The results show that shading could significantly increase the contents of organic matter, total nitrogen, hydrolyzed nitrogen, total phosphorus, available phosphorus and available potassium in soil layer of 0-20 cm. In addition, the organic matter in the soil of shading tea garden reached 49.81 g?kg-1, which was significantly higher than that of the control (32.50 g?kg-1, P<0.05). Shading treatment could significantly improve the activities of urease, invertase, soil protease, acidic phosphatase and alkaline phosphatase in soil (P<0.05). The microorganism related indexes such as bacteria and fungi Shannon-wiener diversity indexes (H) and Richness in shading tea garden were also higher than those without shading treatment. Shading on matcha tea garden could increase the number and activities of soil microorganisms, and upgrade soil enzyme activities which were related to soil nutrient. This would enhance soil quality and facilitate the restoration or rebuilding of the damaged soil ecosystem in tea garden.
