摘要
【目的】针对延庆区苹果腐烂病发生严重的问题,以越冬期间保护树皮从而避免其因寒日灼损伤导致腐烂病菌侵入为切入点,试验不同防护措施,以便有效防治延庆苹果腐烂病,提高苹果种植效益。【方法】在地势、土壤条件不同的两个果园,选择树势基本一致的红富士单株,对树干采取5项防护措施,进行随机区组试验,以病斑新发、复发数量和面积为指标确定防护效果。【结果】结果表明,腐烂病的发生与苹果树地径大小极显著相关;5项措施的防护效果均优于对照,其中内插秸秆外裹无纺布的处理效果最佳。【结论】内插秸秆外裹无纺布的防护方法效果最佳,值得在生产中推广应用。
【Objective】In view of the serious problem of apple valsa canker in Yanqing District,different protective measures were tested to effectively prevent and control apple valsa canker in Yanqing and improve the efficiency of apple planting by protecting the bark during overwintering to avoid the invasion of valsa canker caused by sunburn damage through winter.【Methods】In two orchards with different terrain and soil conditions,single fuji apple tree with basically the same tree vigor was selected,and five protective measures were taken for the trunk.The randomized block test was carried out to determine the protective effect with the number and area of new and recurrent lesions as indicators.【Results】The results showed that the occurrence of rot disease was significantly correlated with the ground diameter of apple tree.The protective effect of the five measures was better than that of the control,and the treatment effect of the non-woven fabric wrapped with the inserted straw was the best.【Conclusion】The protective method of inserting straw wrapped non-woven fabric is the best,which is worthy of popularization and application in production.
