| 摘 要： | 细菌性穿孔病可导致李树叶片大量脱落,树势衰弱,产量降低,品质下降.研究发现,病害的初侵染源来自枝干病斑,生长季节枝、叶、果互相交叉传染.种植感病品种、树势强旺、雨日多、雨量大为该病的流行因素.选用抗病品种、消除初侵染源、加强栽培管理、生长期用药控制是防治该病的有效措施.

| Abstract: | Weakened the trees,dropped the output ,fallen the leaves and deterioted the fruit quality are caused by the bacterial spot-hole of plum(Xanthomonas campestris pv.Pruni (Smith)Uye).The study shows that the initial infection source of the disease is the disease spot on the branches.In the growing season branches,leaves and fruits can infect one another.The epidemic factors of the disease are:planting the susceptible varieties,overgrowing the trees,raining more days and more rainfall.Choosing the resistant varieties,eliminating primary infection sources,strengthening cultural management and controlling by chemicals during the growth season are used for the efficient control of the disease. |
