摘要：杨树是东北地区绿化造林的主要树种，分布广，类型多，适应性较强，成熟杨树高大笔直，树形美观，受到广大种植户的喜爱。但是，杨树具有较差的抗逆性，易发生病虫害，不同品种适应土壤气候条件的能力具有显著差异。地区不同或立地条件不同，其抗病能力也不尽相同，要适地适树。为确保杨树速生丰产，提高经济收益和社会效益，本文探讨了杨树速生丰产林栽培技术要点。

Abstract： Poplar is the main tree species for greening and afforestation in Northeast China. It is widely distributed， has many types， and has strong adaptability. Mature poplars are tall and straight， with beautiful tree shapes， and are loved by the majority of planters. However， poplars have poor stress resistance and are prone to pests and diseases. Different varieties have significant differences in their ability to adapt to soil and climate conditions. Different regions or different site conditions have different disease resistance capabilities， so it is necessary to adapt the site to the tree. In order to ensure fast-growing and high-yield poplars， and improve economic and social benefits， the key points of cultivation techniques for poplar fast-growing and high-yielding forests are discussed in this paper.

我国十分重视造林绿化，大力发展林业经济和林业产业，扩大林业规模，提高森林覆盖率。基于东北地区的气候、自然条件和生态环境实际，决定了在该地区造林和栽培速生丰产林的难度较高。杨树是東北地区造林绿化的主要树种，多用于农田林网、材林及固沙林等绿化种植，由于分布广，类型多，适应性较强，抗旱抗寒性能较高，耐盐碱，生长速度快，成熟杨树高大笔直，树形美观，受到广大种植户的喜爱。杨树是速生树种，抗逆性普遍较差，易发生病虫害，不同品种适应土壤气候条件的能力具有显著差异。地区不同或立地条件不同，其抗病能力也不尽相同，要适地适树。为确保杨树速生丰产，提高经济收益和社会效益，探讨了杨树速生丰产林栽培技术要点，以方便基层制定科学有效的栽培管理方法，促进林业资源的可持续发展，具体如下。
