| 摘 要： | 作者在广泛收集牡丹江市1951～1985年稻瘟病发生历史资料和相关气象资料的基础上,采用系统分析方法和电子计算机技术对资料进行系统分析,建立了由“发生趋势预测模型、产量损失预测模型和药剂防治经济效益估计模型”组成的综合防治决策模型。自1991年用于生产,累计指导防治面积500hm~2,所做出的决策完全正确,经济效益和生态效益显著。

| Abstract: | Based on systematically analysing the data of the rice blast occurence and the climatic factors (1951-1985) in Mudanjiang Region-one of the major rice districts of Heilongjiang Province and computer techniques, a decision model for integrated control of rice blast was established. It consisted of the predictive model of epidemical tendency, yield loss predictive model and the estimation model of economic benefit for fungicide control. By using this model in rice fields of 500 hm2 since 1991,decisions of control were proved to be correct and the benefit was remarkable. |
