我省常年麦播面积7000多万亩,总产量150—165亿公斤。为了保证我省小麦继续高产稳产,需要对我省“七五”期间小麦病虫害的发生趋势做出客观的估计,以便作好防治准备。根据个人的调查分析,先就我省为害最严重的小麦条锈病的发生趋势作一初步估计。目前,虽然还难以作出准确的估计,但是,根据小麦条锈病在我省发生的历史,小麦品种抗条锈性的变化,品种更换趋势,小麦条锈病菌生理小种致病力的变异和我省春季雨水的变化等情况,可以作出大概估计。这对制定我省“七五”期间防治小麦条锈病工作是有一定意义的。
Our province perennial wheat sown area more than 7,000 mu, with a total output of 150-165 billion kg. In order to ensure the high and stable yield of wheat in our province, we need to make an objective estimate of the occurrence trend of wheat pests and diseases during the “Seventh Five-year Plan” in our province in order to make preparations for prevention and treatment. According to the personal investigation and analysis, we first make a preliminary estimate of the trend of wheat stripe rust in our province. At present, although it is still difficult to make an accurate estimate, according to the history of wheat stripe rust occurring in our province, the changes of resistance to stripe rust in wheat varieties, the variety changing trend, the pathogenicity variation of wheat stripe rust races and me Provincial spring rainfall changes, etc., can make a rough estimate. This is of great significance to the formulation of the prevention and control of wheat stripe rust in the “Seventh Five-Year Plan” period of our province.
