摘  要：
对驻马店全区进行果树病害普查,结果发现,梨轮纹病发生比较严重,发病率占总栽培面积的68.8%,枝干叶片和果实上的发病率达45%以上,造成树势衰弱,果品质量差,增产不增收,严重影响了果农种植梨树的积极性。为有效控制梨轮纹病的发生和蔓延,对梨轮纹病进行了定园、定点观察记载和综合防治,取得了较为显著的效果,使轮纹病的发病率由防治前的45%以上降至3.2%~2.1%。文中阐述轮纹病在枝干、叶片和果实上的症状诊断。分析病原菌的越冬部位和形态,病菌的释放和传播,枝条和果实的发育阶段与侵染的关系等梨轮纹病的发病特点及规律。提出消除病原、加强栽培管理、药剂防治等综合防治轮纹病的措施。

摘  要：
Based on the general investigation of fruit tree diseases,the results showed that the disease of pear ring rot occurred relatively seriously,accounting for 68. 8% of the total cultivated area,and the morbidity rate of leaves and fruits on the branches was more than 45%,which made trees weak,fruit quality poor and production increase without higher income,seriously affecting the farmers' enthusiasm of planting pear. In order to effectively control the occurrence and spread of pear ring rot,the observation records in the fixed garden and point and the measures of comprehensive prevention and control were taken on the disease of pear ring rot,by which,the morbidity rate was reduced from 45% to 3. 2% ~2. 1% and the effect was comparatively significant. By analyzing the morbidity characteristics and laws of the overwintering position and form of pathogenic bacteria,the release and spread of germs,the relationship between the growth of branches and fruits and the impregnation,the integrated control measures to eliminate the etiology, strengthen cultivation and management, and utilize chemical control were carried out.
