Utilizing Multivariate Regression Modeling and Spectral Derivative to establish five function pattern cotton dry matter accumulation modeling based on Ratio Vegetation Index and Normalized Difference Vegetation Index,all correlation coefficient is highly positive(α=1%,n=96),based on RVI modeling has a higher precision than NDVI does,hyperbolic curve fitting,exponential curve fitting and logarithmic curve fitting have further improved analysis against cotton dry matter accumulation.

利用北疆8个棉花主栽品种(其中2个棉花品种设4水平种植密度)的各生育期冠层高光谱数据，经多元统计分析与光谱微分处理，建立了基于比值植被指数和归一化植被指数的5种函数形式的棉花干物质积累估测模型，相关系数均达到了极显著水平(α=1%，n=96)。

The results show that the SI value of MAP is the logarithmic function of the mass concentration of P, of ammonium N and of Mg, respectively, and increases with the increase of the mass concentration of each element, The SI value of MAP is a polynomial function of the solution pH value, and the optimum pH value for the crystallization of MAP is 9.0 and increases slightly with the increase of N/P. Moreover, the SI value of MAP is a power law function of the solution ionic strength but decreases with its increase.

计算结果表明，磷酸铵镁的饱和度指数与氮、磷、镁的质量浓度分别呈对数函数关系，并随任何一个因子的增大而增大；与溶液pH值呈多项式函数关系，结晶反应的最佳pH值为9.0，并随溶液中氨氮与磷摩尔比的增大而略升；此外，磷酸铵镁的饱和度指数与溶液离子强度呈幂函数关系，随离子强度的增大而减小。
