摘要
通过物理清园、综合清园和二次综合清园措施,观测核桃黑斑病防控效果,发现清园可降低病害侵染程度,实行冬春两次综合清园更有利于杀灭越冬病原菌,降低病害侵染程度,防控效果更好。
By taking garden cleaning measures,including physical garden cleaning,comprehensive garden cleaning and secondary comprehensive garden cleaning,the prevention and control effect of walnut black spot disease was observed.It was found that garden cleaning in winter and spring could be more beneficial to kill the overwintering pathogenic bacteria and reduce the degree of disease infection,showing a better prevention and control effect.
