Abstract: Effects of film mulchings different in mode on activities of soil hydrolase and oxidoredutase were studied. Results show that overall film mulching significantly increased their activities of soil hydrolase and oxidoredutase. The activity of soil hydrolase basically decreased with the increasing of soil depth, but that of soil oxidoreductase displayed a reverse trend. Sucrase was positively related to urease and alkaline phosphatase in activity (α=0.05), while alkaline phosphatase was negatively related to nitrate reductase in activity (α=0.01).
Key words: film mulching, planting mode, soil enzyme activities, dryland
