Abstract: Using the Laiyang long-term positioning plots established in 1978,to study the effect of different fertilization treatments on soil enzyme activities and interannual dynamic characteristics. According to 10 years of research,we find that different treatments overall order of soil enzyme activity is M NPK NP N NK CK. With the increase of service life soil phosphatase,invertase and catalase activities increased year by year. Its interannual variation went forward volatility and the difference is significant. The interannual variation of invertase and phosphatase was similar and went forward volatility. The interannual variation of catalase was contented the " V" similar trends and most of them appear negative growth. Otherwise,The difference between urease interannual variability of organic manure and chemical fertilizer volume was highly significant. The different treatments of chemical fertilizer was not significant.

Key words: Long-term fertilization, Non-calcareous alluvial soil, Soil enzyme activity, Interannual dynamics
