水稻褐稻虱、粘虫、白叶枯病及小麦赤霉病是我省主要的常发病虫害。一九七五年以来,就我省这几种稻麦主要病虫害的发生流行和为害程度的有关因子进行了调查研究分析,找出其显著相关的因素,做为病虫预测的指标。并经过几年的多点验证,初步认为预测的准确性较为可靠,可供试用推广。 Rice brown planthopper, armyworm, bacterial leaf blight and wheat scab are the main pests and diseases in our province. Since 1975, we have investigated and analyzed the prevalence and degree of harm of major pests and diseases in rice and wheat in our province, and found out their significant related factors as indicator of pest and disease prediction. And after several years of multi-point verification, initially believed that the accuracy of the forecast is more reliable for trial promotion.
