我省闽西北内陆山区小麦抽穗扬花期正值阴雨连绵、气温上升的霉雨季节,加以山区雾多湿度大,小麦赤霉病发生频繁而又严重。从一九七三至一九八○年的八年中有六年是重病年,二年是中病年;大流行年份,病穗率高达60～100％,减产3～4成,严重的颗粒无收;中病年病穗率也达20～40％,减产1～2成。为了弄清小麦赤霉病发病的因素和选育抗赤霉病品种,一九七二年以来我们开展了这两方面的研究。现将工作进行情况小结如下: In northern Fujian inland mountainous areas of wheat heading and flowering coincided with the continuous rainy season, the temperature rise of the moldy rainy season, to be more foggy and humid mountain, wheat head blight occurred frequently and seriously. Six years from 1973 to 1980 were six years of critical illness and two years of sickness. In the pandemic year, the rate of panic disease was as high as 60% to 100% and the yield was reduced by 3% to 40%. Serious Particle confiscated; disease sick ear rate also reached 20 ~ 40%, cut 1 to 2 percent. In order to understand the factors that affect the occurrence of wheat scab and to breed the scab varieties, we conducted these two aspects since 1972. The work is summarized as follows:
