- Abstract:
-
To investigate the changes of soil hydrolase activities under application of corn straws with manure,N and P fertilizer,a field experiment was conducted.The results showed that in corn growing stage,invertase activity in the SNP treatment was 60.09± 2.74 mg GLU/(g·24 h),which was 28.09±1.79% higher than the control treatment,urease activity in the SNP treatment was 2.86±0.10 mg NH3-N/(g·24 h),which was 1.04±0.03 times higher compared to the control treatment,alkaline phosphatase activity in the SN treatment was 4.01±0.05 mg phenol /(g·24 h),which was higher than the control treatment by 0.28±0.05 mg phenol /(g·24 h),there kinds of soil hydrolase activities in the straws returning treatments were higher than the control treatment,the manure fertilizer and N,P fertilizer combined application play different roles in different growing stages and different soil hydrolases.Significant correlation was found between the uraese activity and the invertase activity,soil temperature,but not among the invertase activity,alkaline phosphatase activity and soil temperature.
