本项研究应用系统分析和电算模拟技术,分析了豫北黄河流域稻区第三代稻纵卷叶螟与天气、栽培、营养、天敌、品种、其他病虫害等环境因素的相互关系。从近400个环境条件中选择14个关键因素,组建了稻纵卷叶螟的预报系统模型。用电子计算机进行模拟运算,能够向领导机关提供发生趋势预报,向技术部门提供技术指导预报,向农户提供防治预报,有6种防治方案供农民选择,改变了过去预报、防治一刀切的现象。验证吻合率为80%。
In this study, the relationship between environmental factors such as weather, cultivation, nutrition, natural enemies, cultivars and other pests and diseases was analyzed using systematic analysis and computer simulation techniques. 14 key factors were selected from nearly 400 environmental conditions and a prediction system model of rice leaf roller was established. Using computer simulations can provide lead agencies with trend forecasts, provide technical guidance to technical departments and provide prevention and control forecasts to farmers. There are six types of prevention and control programs for peasants to choose, changing past forecasts and preventing and managing them across the board. Verify the anastomosis rate of 80%.
