台州地区农技总站等单位完成的“玉米苗枯病病原及防治技术研究”课题,最近在杭州通过鉴定。玉米苗枯病是近年发现的一种植物病害。1990年在浙江省台州、金华等地的不少县(市)暴发成灾。天台县春玉米发病面积达到3500余亩,占种植面积的77.8％,株发病率一般在50％以上,其中500多亩死苗严重,耕掉重播。全县春玉米因此减产35万千克,经济损失24.5万元。为探明玉米苗枯病的病原,尽快找到有效的防病措施,当年就组成课题组进行系统研究。三年来,科研人员
Taizhou Prefecture Agricultural Technology Terminus and other units completed the “maize blight pathogen and prevention and treatment technology” project, recently passed the appraisal in Hangzhou. Corn seedling blight is a plant disease found in recent years. In 1990 in Taizhou, Zhejiang Province, Jinhua and other places in many counties (cities) outbreaks. The incidence of spring maize in Tiantai County reached more than 3,500 mu, accounting for 77.8% of the acreage. The incidence of strains was generally above 50%, of which 500 mu were severely dead and severely replanted. The county spring corn thus cut 350,000 kilograms, the economic losses of 245,000 yuan. In order to find out the pathogen of corn seedling blight and find out effective disease prevention measures as soon as possible, the research group was composed to carry on systematic research. Three years, researchers
