5.The results indicated: (1) during the jointing stage of winter wheat, the differences of catalase activity among different measures of soil water utilization are significant in shallow soil, in which the catalase activity of furrow planting with straw mulch is the highest and that of row-spacing-reduced and close planting is the lowest; (2) the trends of catalase activity versus depth are almost the same for different treatments, looking like an inverse S; (3) for furrow growing without mulch, the activity of soil catalase in the furrow is higher than that in the ridge; (4) soil catalase activity reflects some effects from different techniques of soil water utilization and may be used as a indicator for micro-eco-environment in the fields.
