近几年,因有害生物防治成本比较高,高于木材收益,在林业生产中出现树木发生食叶害虫,但无人防治的情况。应用背负式烟雾机防治林木食叶害虫防治成本较低,每天用柴油50元,人工费用200元,防治成本只要250元/天。一、烟雾机防治原理将农药和柴油混合,通过汽油机产生高温,使混合液雾化,以烟的形式飘到树叶上,从而杀死食叶害虫。烟雾机比较适用于大面积的片林防治,其防治食叶害虫速度快、效率高,是一种比较理想的器械。
In recent years, due to the relatively high cost of pest control, higher than the benefits of timber, the emergence of forestry in the production of leaf pests, but unmanned control of the situation. Application knapsack smoke machine prevention and control of forest leafy pests lower cost, daily use of diesel 50 yuan, labor costs 200 yuan, prevention and control costs as long as 250 yuan / day. First, the smoke machine principle of prevention and control of pesticides and diesel mixture, through the gasoline engine to produce high temperature, the mixture of atomized, floating in the form of smoke on the leaves, thus killing leafy insects. Fog machine more suitable for large areas of forest control, the prevention of leaf-feeding pests fast, high efficiency, is an ideal device.
