整合分析氮磷添加对土壤酶活性的影响
Effect of nitrogen and phosphorus addition on soil enzyme activities: A meta-analysis
摘要
Abstract
We conducted a meta-analysis to analyze the effects of nitrogen (N) and combined N and phosphorus (N +P) addition on soil enzyme activities,which being involved in soil carbon (C),N,and P cycles as well as oxidative processes.Nitrogen addition significantly increased the activities of soil C acquisition enzymes,N acquisition enzymes,and P acquisition enzymes by 6.9%,5.6% and 10.7%,respectively,while the enhancement was much stronger under N +P treatment with 13.4%,37.4% and 13.3%,respectively.In contrast,both N addition and N+P addition decreased the activities of oxidative enzymes by 6.1% and 0.4%,respectively.The effect sizes of N and N+P addition on soil enzyme activities varied with ecosystem types,N fertilizer types,N addition rates,and the duration of fertilization experiments.Our results suggested that the changes in soil microbes and their enzymes under increasing N deposition and P addition would have profound impacts on soil biogeochemical processes and functions.关键词
