传统的农药施用方法,虽然对害虫的发生发展起到一定的防治作用,但同时又带来对环境的污染,杀死害虫天敌等副作用。采用树干注射法,可将具有内吸作用的杀虫剂、杀菌剂的稀释液注入树干,利用树体的代谢动力和呼吸动力使药液随蒸腾液流而上升到树冠,从而起到防治病虫害的作用。此方法也可将微量元素肥料、植物生长调节剂的稀释液注入树干,起到补充树体营养和调节树体生长的作用。用树干注射法具有携带器具方便(每台器具只有0.25公斤)、定量注入药液、不污染环境、不杀死害虫天敌,省工省时等优点,是林木、果
Traditional methods of pesticide application, although the prevention and treatment of the occurrence and development of pests play a role, but at the same time bring pollution to the environment, kill pests and other side effects of natural enemies. Using trunk injection method, insecticide and fungicide with internal absorption can be injected into the trunk of the trunk, using the metabolism and respiratory motility of the tree to make the medicinal solution rise to the canopy with the transpiration flow, thereby preventing pests and diseases Role. This method can also be microelements fertilizers, plant growth regulators diluted into the trunk, play a role in tree nutrition and regulates the growth of the tree. With the trunk injection method has the convenience of carrying equipment (each device only 0.25 kg), quantitative injection of liquid, do not pollute the environment, do not kill pests natural enemies, saving time and labor, etc., is the tree, fruit
