摘要
经 5年系统研究得出 ,影响猕猴桃溃疡病发生流行的特点是 ,海拔 75 0m以上的果园发病重 ,向阳坡发病重于背阳坡 ,不同品种发病差异显著 ,金丰品种易感病 ,金魁品种高度抗病 ;树龄越大 ,病株率越高 ;不同枝龄比较 ,一年生枝条病枝死亡率和枝条死亡率最高 .6种药剂以加瑞农和硫酸链霉素抑菌效果最好 .
According to the systematic study for 5 years,this paper dealt with the ecological factors affecting prevalence of kiwifruit bacterial canker.The disease was more serious in the orchards with above 750 m in elevation,and more serious at mountain slope facing south than facing north.Incidence differed significantly among cultivars,with easy disease infection for Jinfeng,and strong disease resistance for Jinkui.The older the trees,the more the diseased plants.The one year old twigs had highest death twig incidence of diseased twigs and death twig incidence than other twigs.Among 6 tested bacteriocides,Jiaruinong and streptomycin showed best bacteriostatic effect.
