摘要
文章以迭部县地区的云杉为研究对象,考察了针叶喷涂法与树冠喷涂法对云杉叶锈病的防治效果,并分析对比了不同药剂施用后的病株减退率。结果显示:在早春时采用波尔多液对云杉针叶进行喷涂对其叶锈病防治效果较好,病株减退率为80.36%;在5月底采用敌锈钠500倍液对树冠进行喷洒对其叶锈病防治效果较好,病株减退率达到了86.61%。
This paper took the Picea asperata Mast.in Dibu County as the research object,investigated the effect of needle spraying and crown spraying on the control of Picea asperata Mast.leaf rust,and analyzed and compared the decline rate of the disease plant after the application of different insecticides.The results showed that the decline rate of infected plants was 80.36%.At the end of May,spraying the crown with 500 times solution of dirustum sodium had a good effect on the control of leaf rust,and the reduction rate of diseased plants reached 86.61%.
