北票市为朝阳市谷子主要产区,种植面积占粮谷的30%以上,近两年谷子锈病普遍发生,且早衰现象明显,去年,仅锈病大流行全市就减收谷子12500万千克。作者当年考查,发现谷子品种间耐锈病性差异十分显著。为了减轻锈病危害,确保北票谷子生产优势,在去年初筛谷子耐病品种的基础上,今年对一些有希望的品种进行了系统的试验示范,取得了较好的效果,现整理报告如下:一、材料与方法品种及其来源:23-4、381建平县农科所提供。黑
Beipiao City is the main producing area of the millet in Chaoyang City. The acreage accounts for more than 30% of the cereal grains. In the past two years, mildew rust generally occurs and the phenomenon of premature aging is obvious. Last year, the city only reduced the amount of millet by 125 million kilograms. The author test that year, found that millet varieties rust resistance is very significant differences. In order to reduce the hazard of rust and ensure the production superiority of Beipiao millet, we conducted a systematic demonstration of some promising varieties this year on the basis of screening the resistant varieties of millet at the beginning of last year and achieved good results. The report is summarized as follows: , Materials and methods Varieties and their sources: 23-4,381 Jianping County Agricultural Science Institute. black
