摘要
肥料效应函数法是测土配方施肥技术中较为常用的方法。以田间小麦"3414"肥料试验的具体研究为例,阐述如何通过"3414"试验获取肥料效应函数法测土配方施肥参数。总结分析过程,归纳其主要步骤为:①建立关于模型变量的数据集;②拟合肥料效应模型;③计算施肥参数。
Fertilizer effect function method is commonly used in soil testing and formulated fertilization technology. The ＂3414＂ fertilizer experiment was taken to introduce how to acquire formulated fertilization parameters. Three main procedures include establishing the data set about the model variables, fitting the fertilizer response model and calculating the fertilization parameters.
