近年来,小麦赤霉病在我区的山区、半山区为害有逐年严重的趋势。它为害所造成的后果,不仅是减产,而且赤霉病菌分泌在麦里的毒素还严重影响着人、畜的健康,这种双重性的为害,对小麦生产发展威胁极大。因此为我区70～80万亩冬小麦着想,我们从一九七六年冬季开始,到本病连年严重发生的山区去,同当地的农技人员一道,做了三年的研究,现将结果总结于下。 一、消长规律与预测 消长观察田设在永春县农场,参加品种以晋系小麦为主,随机排列,一九七七年种14个,一九七八年种69个。当播种后,对每个品种的出苗、齐穗、始花、盛花等生育期进行记载。
In recent years, wheat scab has been worsening year by year in the mountainous areas and semi-mountainous areas of our region. The consequences of its harm not only cut production, but the toxin secreted by Fusarium graminearum also has a serious impact on the health of people and livestock. The dual nature of the damage poses a great threat to the development of wheat production. Therefore, for my area of 70 to 800000 acres of winter wheat, we from the beginning of winter in 1976, to the serious disease occurred in successive mountainous areas, together with the local agricultural technicians, for three years of research, the results will now Summarized below. First, the growth and decline of the law and forecast the growth and decline observed Tian farm located in Yongchun County, Jin wheat varieties to participate in the main, randomly arranged in 1974, 14 species, 1978, 69 species. When sowing, the emergence of each species, full heading, beginning of flowers, flowers and other reproductive period records.
