种植抗病品种是防治谷子白发病最经济有效的措施。1982年我们对部分谷子品种和资源进行了抗性鉴定。实验在承德地区农科所试验场进行。实验地地势平坦,沙壤土,前茬玉米,PH 值7.0供试材料322份。接菌方法是将上年秋季采集的病残体搓碎过箩获孢子粉。孢子粉与细潮土按1比5混合均匀,播种前一天,每2克种子加菌土5克,装袋摇匀,播种时同时播下。谷子成熟时调查,记载病茎和健茎数,计算病茎率。按抗性
Planting disease-resistant varieties is the most economical and effective measure to prevent and cure mildew white hair. In 1982, we identified some of the millet varieties and resources for their resistance. Experiments were carried out in the agricultural field of Chengde Prefecture. Experimental flat terrain, sandy loam, pre-crop corn, PH value of 7.0 test materials 322. The method of inoculation is to pick up the spores of the diseased body collected in the fall of last year. Spore powder and fine soil by 1 to 5 mixed evenly, the day before sowing, 2 grams of seeds per gram of bacteria plus 5 grams, bagging shake, sowing at the same time broadcast. Mature investigation of millet, record the number of diseased stems and stems, calculate the rate of diseased stems. According to resistance
