| 摘 要： | 选取5种杀虫剂防治杨干象,杨干象杀死率及排序：2%高效氯氰菊酯（杀死率95.09%）〉40%氧化乐果乳油（杀死率88.06%）〉氯氟.毒死蜱（杀死率82.27%）〉10%灭多威＋10%辛硫磷（杀死率80.19%）〉2%阿维菌素（杀死率55.53%）.对杀虫剂在树干中的残留浓度分析发现：氧化乐果在整个树干中的残留浓度比较均匀;阿维菌素则随高度增加残留浓度迅速减少,到距注药孔1.5 m高度后浓度趋于稳定.利用染色标记法研究了杀虫剂在银中杨树干中的输送轨迹,发现其呈扇状螺旋式上升;为使药液均匀分布于树干中,注药时应使注孔尽量接近地表,以均匀分布2～3个注孔为宜.

| Abstract: | To select five kinds of pesticides to control Crptorrhynchus lapathi L.,kill rate and capacity showed that 2% beta-cypermethrin（kill rate 95.09%）40% omethoate（kill rate 88.06%） Chlorine fluorine·chlorpyrifos（kill rate 82.27%）10%methomyl＋10%phoxim（kill rate 80.19%）2% avermectin（kill rate 55.53%）.Residue concentration of pesticide in Populus alba×P.berolinensis trunk was different.Residue concentration of omethoate was more uniform.Residue concentration of avermectin was rapidly declined with the increase of trunk height,however,it became stable above 1.5 m height.The transport patterns of Populus alba×P.berolinensis was sartorially radial and spiral ascending manner.We should close to the ground and evenly distribute 2 or 3 holes when we drill holes for trunk injection of pesticides. |
