1987～1989年在我国8个主产烟省23万亩烟田上应用83增抗剂,小区对比、大田示范试验证实,防治花叶病毒病效果为44.4%～54.8%;促进植株生长,单叶重增加12.18%,平均每亩增产9.14%～11.01%;提高烟碱含量,上等烟比率提高12.11%～13.12%,斤烟均价提高0.22～0.24元。防病、增产、优质的效果创造了每亩增收60.60～123.11元的经济效益。83增抗剂诱导植物抗、耐病性提高,加强了植物病毒生态体系中自然控制因素——品种抗病性的作用。以此为主,兼具控制病原病毒和传播介体的多种功能:体外钝化病毒,抑制病毒初侵染,降低植物体内病毒的扩散速度,影响蚜虫的探食行为,降低蚜传发病率。
From 1987 to 1989, 83 antagonists were applied to 230,000 mu of tobacco fields in 8 major tobacco-producing provinces of China. Community comparison showed that the effect of preventing and curing Mosaic virus was 44.4% ~ 54.8% The average increase of 12.18% per acre, yield 9.14% ~ 11.01% per acre; increase the nicotine content, superior tobacco increased 12.11% ~ 13.12%, the average price of jinan 0.22 ~ 0.24 yuan. Disease prevention, increase production, high-quality results have increased the yield per acre 60.60 ~ 123.11 yuan of economic benefits. 83 enhancer resistance induced plant resistance, increased disease resistance, and strengthen the natural plant virus control system factors - the role of disease resistance. Based on this, it has many functions of controlling the pathogenic virus and the transmission mediator: In vitro passivating the virus, inhibiting the initial infection of the virus, reducing the virus diffusion rate in the plant, affecting the feeding behavior of aphids and reducing the incidence of aphids .
