摘要
田间条件下总是要对付多种有害生物。农业生态系统分析方法考虑有害生物天敌、环境及水稻等相互关联因素作为农民决策依据。按照经验推理法则，由一组农民按培训后的办法田间１ｍｉｎ以内取样判断，对多种病虫防冶决策，经比较测试，有可能取代按防治指标取样并更符合农民实践需要。
In actual field conditions, several pests are always involved.The agro-ecosystem analysis,the interdependence of pest,natural enemies,environment and rice are considered in the decision of farmers'.An action is done by groups of trained farmers.Some situation measures are quickly sampled within 60 seconds.According experienced approach or rules of thumb,the technique can improve farmers'decisionmaking.Comparison tests showed that instead of ETL-based methord, this procedure may meet the needs of farmers.
