| 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。 |

|
| Abstract: |
| 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,suc... |
