在众多的林业灾害中病虫害是对植物影响最严重的,在各种害虫迅速繁殖的影响下,其影响范围可想而知,并且可以做到短时间内就可以很大面积森林的死亡与衰败,造成巨大的林业经济财产损失。因此,防治病虫害工作是不容缓,它是保障林业经济的重要基础,也可以在生态效益方面发挥巨大作用。我国对于病虫害的防治水平只停留在传统的使用农药的方式对害虫进行杀除,虽然这种方式可以起到一定的作用,但只是短时间的作用,对于长久的除病虫害战役并无太大的用处,这种方式的另一种缺陷是,在林业面积过大时喷洒工作操作起来并不方便。此外,这种方法也对林区周边的环境有一定程度的破坏。所以,为了使林业经济更好的发展,有必要对无公害防治害虫工作进行一定的研究与探讨,本文就以该内容为基础,对病虫害的发生原因也进行了一定程度的探讨。
Pest and disease in many forest disasters is the most serious impact on plants, under the influence of the rapid propagation of various pests, its scope of influence can be imagined, and can be a very short period of time can be a large area of forest death and decline , Causing huge loss of forestry economic property. Therefore, the prevention and control of pests and diseases is an urgent task. It is an important foundation for ensuring forestry economy and can also play a significant role in ecological benefits. The level of prevention and treatment of pests and diseases in our country only stays in the traditional ways of using pesticides to kill pests. Although this method can play a certain role, it is only a short-term action and not too long for the campaign of pest and disease elimination Another disadvantage of this approach is that it is inconvenient to operate the sprinkler when the area is too large. In addition, this method also has a certain degree of damage to the environment around the forest. Therefore, in order to make the forestry economy develop better, it is necessary to conduct a certain research and discussion on the work of pollution prevention and control pests. Based on this content, this paper also discusses the causes of pests and diseases to a certain extent.
