辽西地区杨树伐根嫁接及萌蘖更新技术

Stump Grafting and Sprout Regeneration Techniques for Populus in Western Liaoning

辽西地区为改善当地生态环境,营造了大量的杨树人工林,部分林分由于品种选择不当、生理过熟等原因质量开始下降,影响了杨树林的生态经济效益,因此,需要对杨树低效林进行更新改造。利用低成本、造林过程简单的伐根嫁接及萌蘖更新技术可以实现杨树林分的快速更新。在结合生产实践的基础上,对辽西地区杨树伐根嫁接、萌蘖更新技术要点以及杨树常见的病虫害防治技术进行总结。

In order to improve the local ecological environment in western Liaoning,a large number of Populus plantations have been established.However,due to improper selection of varieties and physiological over-maturity,the quality of some stands has begun to decline,affecting the ecological and economic benefits of the Populus forests.Therefore,it is necessary to renovate and upgrade the low-efficiency Populus stands.Utilizing low-cost,simple afforestation techniques such as stump grafting and sprout regeneration can achieve rapid regeneration of Populus stands.Based on production practices,this paper summarizes the key points of stump grafting and sprout regeneration techniques for Populus trees in western Liaoning,as well as common pest and disease prevention and control techniques for Populus.
