【摘要】 依据施肥模式实现量化施肥,可以有效地提高小麦生产的经济效益。本研究采用三因素二次回归旋转组合设计方法,将施氮肥、磷肥、有机肥作为施肥变量决策因素,借助微机运算处理和选优,组建旱地小麦高产施肥数学函数模型,并确定旱地小麦施肥模型主因素作用效应顺序和最优组合方案。更多还原

【Abstract】 The economic benefits of wheat Production can be efficiently increased by applying fertilizer at the desired arte according to the model.This paper establishes a mathematican function model of fertilizer application for higher wheat yield in arid areas and determines the sequence of the main factor effects of the model and the optimum plan for combination, using N. P and organic fertilizer as quantitative factors by way of quadratic regression whirling combination calculated and optimized by the microcomputer.更多还原
