球根海棠感染病毒后,迅速出现叶片斑驳、褪绿、畸形或花朵碎色等症状。由于球根海棠多采用鳞茎分株或扦插繁殖,病毒由此传播。蚜虫也是种植期传播的主要媒介,人工除蕾的工具、种植器具等若消毒不净也会传播病毒。另外,雨水淋溅同样可以造成病毒传播。目前病毒病的药剂防治效果不佳,因此一旦发现植株染病,只能拔除销毁,对于名贵品种,甚为可惜。经长期观察,多次实验,发现大蒜浸汁对球根海棠病毒病有治疗作用,大部分品种可以治愈。先将染病植株上所有显现病害症状的枝叶和花朵全部摘去,摘除后销毁并洗手。有些碎色花很好看,可不摘去,但是残花、落花一定要
Begonia infected with the virus, the rapid emergence of mottled leaves, chlorosis, deformity or flower crushing and other symptoms. As the root tuber more use of bulb ramets or cutting propagation, the virus spread. Aphids are also the main medium of propagation during planting period. Artificial tools such as buds, planting utensils, etc. can also spread the virus if they are not disinfected. In addition, rain spills can also cause the virus to spread. At present, the effect of preventing and curing the virus disease is not good, so once the plant is found to be infected, it can only be removed and destroyed, which is a pity for the rare breed. After long-term observation and many experiments, it was found that the garlic dip juice has the therapeutic effect on the root begonias virus disease, and most of the varieties can be cured. First of all infected plants show all the symptoms of disease foliage and flowers all removed, removed and washed after the removal. Some broken color flowers look good, do not pick it, but residual flowers, flowers must be
