目前,速生丰产林病虫害防治工作主要存在三方面的问题:一是对病虫害发生严重性的认识程度不够;二是缺乏必要的防治技术;三是缺少必备的防治机械,不具备快速高效的防治能力。要作好速生丰产林病虫害的防治工作,就要坚持“预防为主,综合治理”的方针,重点抓好四个环节: 一是要提倡营造混交林。混交林可以形成稳定的森林生态系统,可以提高对病虫害的自然抗御能力。在造林工作中,要充分利用不同树种、不同植物对病虫害的相互制约作用,采取树种间混交、品种间混交、林灌混交、林草混
At present, there are mainly three problems in the control of pests and diseases in fast-growing and high-yield forests: first, the degree of understanding of the seriousness of pests and diseases is not enough; second, the necessary prevention and control technologies are lacking; third, lack of necessary prevention and control machinery and rapid and effective prevention and control ability. To make quick-impact and high-yield forest pest and disease control work, we must uphold the principle of “prevention first, comprehensive management,” and focus on four aspects: First, we must promote the construction of mixed forests. Mixed forest can form a stable forest ecosystem, can improve the natural resilience to pests and diseases. In the afforestation work, we must make full use of different tree species, different plants on the mutual restraint of pests and diseases, to take the tree species mixed, inter-species mixed, mixed forest and bush, forest and grass mixed
