1988-1991年在长江以南的湖南省衡阳市和长江以北的河北省7个县市对“912”植物病毒钝化剂进行了小区和田间示范试验,表明“912”对辣(甜)椒病毒病有明显的防病增产作用,处理区的发病率为25％～49.3％,病情指数为12.75～31;对照区的发病率为46.6～92％,病情指数为20.25～61,防效为39.82％～53.7％。对辣椒的株高、开花、挂果数有明显的促进作用,增产率为11.69％～18.3％。室内“912”测试表明“912”对烟草花叶病毒和黄瓜花叶病毒有体外钝化作用,降低植株体内的病毒浓度;不仅对辣(甜)椒病毒病和蕃茄病毒病有保护作用,而且对植株生长有促进作用,可以提高株高日增长量和叶绿素含量。
From 1988 to 1991, community and field demonstration experiments of “912” plant virus passivating agent were carried out in seven counties and cities in Hengyang, Hunan Province, south of the Yangtze River, and in the north of the Yangtze River in China. The results showed that “912” Pepper virus disease has a significant increase in disease prevention and treatment, the incidence of treatment area was 25% to 49.3%, the disease index was 12.75 to 31; control area incidence was 46.6 to 92%, the disease index was 20.25 to 61, anti-efficacy 39.82% ~ 53.7%. Pepper’s plant height, flowering, fruiting number has a significant role in promoting the yield was 11.69% ~ 18.3%. The indoor “912” test showed that “912” had in vitro passivation effect on tobacco mosaic virus and cucumber mosaic virus, and reduced the virus concentration in the plant; it not only had protective effect on spicy (sweet) pepper virus disease and tomato virus disease, but also It can promote the plant growth, increase the plant height and chlorophyll content.
