不同育苗方式对番茄溃疡病发病的影响

Effect on the different seedling way to the bacterial canker of the tomato

通过对番茄溃疡病关键防控技术研究发现,种子消毒是番茄溃疡病最关键的防控技术,但培养壮苗也是番茄溃疡病重要的防控环节。文章就不同育苗方式,即单个育苗钵育苗、纸筒育苗、常用育苗盘育苗对番茄溃疡病发病的影响进行试验。结果认为,单个育苗钵育苗、纸筒育苗基质多,根系发达,幼苗健壮,移栽时避免造成根部伤口,室内及田间溃疡病发病明显低于常用育苗盘育苗处理。

By research on the key prevention and co ntrol technology to bacterial canker of tomato, seed disinfection is the most crucial technology during prevention and control tomato ulcer disease, and robust seedling cultivation is important too.We researched the effect of the three different seedling culture modes with nutrition bowl, paper-tube and plug-seedling on disease incidence of bacterial canker of tomato. The result showed that the disease incidence of nutrition bowl seedling and paper-tube seedling in greenhouse and field is lower than plug-seedling if not hurt the root when we transplant seedlings,with stronger seedlings and developed root of tomato in nutrition bowl and paper-tube.
