七十年代以来,我国番茄栽培区普遍发生病毒病,主要毒源是烟草花叶病毒(TMV)和黄瓜花叶病毒(CMV),而国内尚无理想的抗病品种和防治药剂。近几年来,北京农业大学植物病毒研究室和北京师大化学系共同研制的83增抗剂(原称NS—83)是一种由菜籽油制取的耐病毒诱导剂,已于1985年1月22日由农牧渔业部委托北京农大组织有关专家通过成果鉴定并正式生产。我市于1983年接受北京农大植保系梁训生副教授委托,经1983年和1984年田间试验示范,为今后大面积推广应用83增抗剂提供了经验。
Since the 1970s, virus disease has been widespread in tomato growing areas in China. The main sources of virus are TMV and CMV, but there are no ideal resistant varieties and control agents in our country. In recent years, Beijing Institute of Plant Virus Laboratory and Beijing Normal University Department of Chemistry jointly developed 83 enhancers (formerly known as NS-83) is a rapeseed oil made from the virus-inducing agent, in 1985 January 22 commissioned by the Ministry of Agriculture, Animal Husbandry and Fisheries Beijing Agricultural University Organization of experts through the identification of the results and formal production. In 1983, our city was entrusted by Associate Professor Liang Xuesheng of Beijing Agricultural University. After the demonstration in 1983 and 1984, it provided the experience for large-scale popularization and application of 83 enhancers in the future.
