摘要
落叶松是我国林业的重要树种,因其抗寒能力强、生长速度快,在东北地区大面积培育,近年来已在森林发展中形成较高的覆盖率。虽然落叶松的生命力比较顽强,但仍难免遭受病虫害的侵袭。落叶松幼苗培育阶段是病虫害发展比较严重的时期,对落叶松的幼苗发育会造成严重影响和制约。为此,本文针对东北落叶松幼苗培育阶段主要病虫害防治及培育技术进行探讨和分析,并根据病虫害发生规律和危害特点提出相应的防治策略和培育要点。
Larix gmelinii is an important tree species in China’s forestry.Because of its strong cold resistance and fast growth rate,it has a large area cultivation in Northeast China and has formed a high coverage rate in forest development in recent years.Although the vitality of Larix gmelinii is more tenacious,it still inevitably suffers from pests and diseases.The breeding stage of Larix gmelinii seedlings is a serious period of disease and pest development,which will severely affect and restrict the seedling development of Larix gmelinii.Therefore,this paper discusses and analyzes the main pest control and cultivation techniques in the cultivation stage of Larix gmelinii seedlings in Northeast China,and puts forward the corresponding control strategies and cultivation points according to the occurrence law and hazard characteristics of pests and diseases.
