摘要
应用砂滤管法和正交旋转回归设计建立了降水量、地积温和有机肥添加量对有机肥的腐解动态模型。结果表明，降水量与有机肥腐殖化系数成正相关；地积温与有机肥腐殖化系数成负相关；添加量对有机肥腐殖化系数影响不大．模型计算出不同地区不同积温、降水条件下有机肥腐殖化系数的变化值．
A dynamic model of manure humification in relation to rainfall, acuumulated temperature of soil and application amount of manure was established by combining the method of sand-filtrating tube and the design of guardratic rotation regression. The results showed that me manure hamffication coefficient was possitively correlated with the rainfall, but negatively correlated with the accumulated tempreture of soil. The variables of manure humification coefficients can be culcuated from this model in different region, and under differed rainfall conditions
