在离地15—20cm处的树干两侧,用开皮器打两个洞,深至形成层,每个洞附近挂一个容量约60ml的玻璃瓶。瓶内装所用的药液。如40％杀虫双400倍液,80％甲基托布津800倍液等,然后将灯芯一端放在瓶内药液中,另一端插入树干洞口内,用树皮盖住洞口。再用塑料薄膜全部包扎起来,药液通过灯芯引输到洞内,被树体慢慢吸收。此方法对杀灭树干病虫害特有效,既可以防病,又可以治虫。
On both sides of the trunk at 15-20 cm above the ground, use a peeler to drill two holes deep into the formation and hang a glass bottle about 60 ml capacity near each hole. Bottle filled with the liquid used. Such as 40% insecticide double 400 times, 80% thiophanate-methyl 800 times and so on, and then one end of the wick placed in the liquid bottle, the other end into the trunk hole, with a bark to cover the hole. Re-plastic film all wrapped up, the liquid lead through the wick into the hole, slowly absorbed by the tree. This method is particularly effective in killing trunk pests and diseases, which can both prevent diseases and pests.
