Different from the forestry fertilization methods commonly used, the Site & Nutrient Effect Fertilization Model is based on the estimation of site and nutrient effect parameters and related coefficients through field investigation and sample analysis. Operation of the model involves judgment of the necessity of fertilizer supply for a given forest; establishment of the state & dynamic function relationship between forest growth and nutrient uptake; measurement of the soil nutrient intensity and quantity correlation curves; and determination of the profit target equation. The curves and equations of the model are used respectively for determining the optimal target yield increment; the effective nutrient uptake increment required for obtaining the target yield; the quantity of fertilizers for different nutrient elements to be applied; and as well the proper time and methods for fertilizer application. Based on the site and nutrient effect theory, the model is simple in trial treatment and thus easy to handle, with nearly no limitations to different site conditions and tree growth period. Results from the present study indicate that the model can be widely used with relatively high levels of accuracy.

与常规林木施肥试验方法不同 ,林木立地养分效应配方施肥模型是通过立地与养分效应参数及相关系数测定来确定林地施肥的必要性、林木生长与养分吸收的动、静态关系、土壤养分容量与强度曲线和目标效益方程 .基于这一组曲线与方程来确定最佳目标增产量、达标所需的有效养分增量、相应的施肥量与配方、以及最佳施肥时期与方法 .施肥模型的特点是理论性强 ,试验处理简单 ,实践中易于操作 ,适用性广 ,不受区域和林木生长阶段的限制 ,应用中具有较高的精确度和推广价值 .
