美国俄勒岗州大学科研人员,采用一定的施肥措施防治小麦全蚀病,取得较好的防治效果。小麦全蚀病是一种真菌病,它危害小麦根部,使根系发黑和腐烂,进而危害茎部,使麦苗变黄、生长停滞和分蘖减少,造成严重减产。过去防治此病的主要措施是轮作换茬和土壤熏蒸,熏蒸土壤成本昂贵不切实用,此外没有更好的防治措施。科研人员于1977和1978年,在北威拉米特农业试验站,进行了施用不同肥料的防治试验。他们首
University of Oregon researchers in the United States, using a certain amount of fertilization measures to control wheat eclipse, get better control effect. Total eclipse of wheat is a fungal disease that harms the roots of wheat, causing the roots to become black and decay, thus damaging the stems, yellowing the wheat seedlings, arresting growth and reducing tillers, resulting in serious yield losses. In the past, the main measures to prevent and control this disease were crop rotation and soil fumigation, which made the fumigation of soils costly and impractical. In addition, there was no better prevention and cure measures. Researchers in 1977 and 1978, at the North Willamette Agricultural Experiment Station, conducted a different fertilizer control test. They first
