Effect of Different Tillage Practices on Soil Enzyme Activity
By the field experiment, the effect of different tillage practices(Conventional tillage, CT; No-tillage with stubble coverage, NTSC; No-tillage with stubble, NTS) on soil enzyme activity in the semiarid area of western Jilin province was studied. The results showed that the No-tillage with stubble coverage(NTSC) influenced soil enzyme activities deeply to the surface soil before sowing, this may be related to soil temperature changed under stubble mulching treated. No-till and flatten tillage treatment have 9hown a greater impact on the soil urease and soil catalase, but has less affected soil phosphates activity during the maize growing, which No-tillage with stubble(NTS) made a greater impact on the soil catalase and soil urease. With increased, in terms of vertical direction, the trend showed increased first and then downward, but the performance to soil alkaline phosphatase complex.
