摘要
本文以田间试验为基础,论述了应用肥料效应函数法进行不同种植制度的施肥决策,主要进展是:1.对不同种植制度的施肥决策问题进行了分类,提出了最大利润、保险收益和最小成本决策目标;2.提出了适于编写计算机程序的多茬作物经济施肥量计算公式,特别是不同作物的加权价格和加权产量的计算公式,克服了轮作和间套作施肥决策在统计上的障碍;3.建立了计算机施肥决策程序,适于不同种植制度,不同施肥条件和多种目标的施肥决策,有助于实现轮作施肥和区域施肥决策的定量化和计算机化。
This paper deals with the decision making under different croping systems.The main results are as follows:1.The types of probloms of making decision are classified by three criteria,the maxinum profit,ensured revenue and minimum cost.2.The formulas for determining the optimum rates of ferti- lizers and for computer programming,especially the formula for calculating wei- ghted price of products and weighted yeilds have been derived.3.The programs written in BASIC language can be used for multiple objects,such as the decision of making the fertilization under rotation cropping and regional fertilizer recom- mendation,wich help the popularization of computer.
