Abstract: In order to investigate the variation characteristics of hydrogen peroxidase activity in greenhouse soil, the author analyzed hydrogen peroxidase activity in greenhouse soil in 6 districts in Yunnan Province. The results showed that the variation range of hydrogen peroxidase activity in 0-20 cm soil layer was 0.216-2.301 mL/g, with the average of 1.526 mL/g, the variation range of soil hydrogen peroxidase activity in 20-40 cm soil layer was 0.499-2.469 mL/g, with the average of 1.725 mL/g, which were 1.939 and 1.902 mL/g lower than that of the open soil, respectively. The variation rend of soil hydrogen peroxidase activity was increase – decrease - increase with the increase of greenhouse life, and 0-20 cm soil layer and 20-40 cm soil layer had the same variation trend. The soil hydrogen peroxidase activity had a significantly positive correlation with soil pH and total nitrogen. Experiment showed that the soil hydrogen peroxidase activity was related to greenhouse life, soil depth and soil physical and chemical properties, and soil hydrogen peroxidase activity could reflect soil quality.
