摘要
本试验是采用最优设计进行的N、P、K三因素肥料试验,试验结果获得了三个因素与产量间相互关系的函数模型。本文分析了三个因素的产量效应及其交互作用,分别计算出最高产量、最大施肥利润以及不同产量水平最低成本的施肥量及其配比,为合理施肥提供依据。
A fertilizer experiment of N,P,K was conducted by using the superior design method.We have get a function model of corrslation between three factors and yield.This paper describes the yield effects and interaction of the three factors.Applied rates of the highest yield.The best beneficial returns at different yield levels and combining proportion of N,P,K were caculated respectively.This conclusion can be used as a base of peanut fertilization.
