1982年裘维藩教授提出了:烟草坏死病毒病及马铃薯X病毒病的健株根系与病株根系通过接触有遭受感染的可能性,在自然界,蕃茄上的烟草花叶病毒(TMV)能否通过根系接触传毒,国内尚未报道。1986年我们曾发现大棚番茄上的烟草花叶病毒病,病、健株相邻的染病率达10%。1987年4月初,曾进行了系统调查,在10棵定点调查的病株中,先后有相邻的4棵健株发病。1987年4—7月在防虫网室中进行了盆栽试验,砂土系140—150℃干热灭菌20小时.种子系10%磷酸三
In 1982 Professor Qiu Weifan proposed: Tobacco necrosis virus and potato X virus disease of the root system and diseased plant roots by the possibility of exposure to infection, in nature, tomato mosaic virus (TMV) through the root system Contact poisoning, not yet reported. In 1986 we have found that tobacco mosaic virus on greenhouse tomatoes, diseases, health strains adjacent to the disease rate of 10%. In early April 1987, a systematic survey was conducted. Of the 10 diseased plants surveyed by the survey, four consecutive healthy plants were found to have disease. In April-July 1987, a pot experiment was conducted in the insect-proof net room, and the sand was dry-sterilized at 140-150 ℃ for 20 hours. The germination system was 10% tris
