番茄花叶病毒病是近几年发展起来的一种较严重的病害,对番茄产量影响很大;特别对一些中、晚熟品种的危害更为严重.近几年我市番茄产量、质量下降,花叶病毒病的危害也是主要原因之一.据1983年调查,发病率为51％的严重地块达90％.在中国科学院微生物所的指导下,当年从该所引进了弱毒疫苗N14应用于我市番茄花叶病毒病防治试验,取得了较好的防病增产效果。病情指数降低11,平均增产9.9％.在此基础上,1984年我们又进行试验,现将试验情况总结如下:
Tomato mosaic virus disease is a serious disease developed in recent years, which has a great impact on tomato yield, especially for some middle-late-maturing varieties. In recent years, the yield and quality of tomato in our city decreased, Mosaic virus disease is also one of the main hazards.According to the survey in 1983, the incidence of 51% of the serious land of 90% .In the Institute of Microbiology, Chinese Academy of Sciences, when the introduction of the attenuated vaccine from the N14 applied to City of Tomato mosaic virus disease prevention and control tests, and achieved good disease prevention and yield enhancement effect. Disease index decreased by 11, an average increase of 9.9% on this basis, in 1984, we conducted a test, the test is summarized as follows:
