杨树是世界上分布最广、适应性最强的树种,杨树具备早期速生、无性繁殖容易两大特点。因此人们渴望利用杨树解决迅速恢复植被,解决生态问题;迅速种植形成人工林,解决木材问题。针对当前杨树速生丰产林急需发展的需要,根据杨树丰产栽培的科研成果和生产经验,对杨树短轮伐期定向培育技术进行了较系统的总结。 Poplar is the most widely distributed and most adaptable tree species in the world. Poplar has two characteristics of early rapid propagation and asexual reproduction. Therefore, people are eager to use poplar to solve the problem of rapidly restoring vegetation and solving ecological problems, planting planted forests rapidly and solving timber problems. In response to the urgent need of fast-growing high-yield poplar forest, according to the research achievements and production experiences of high-yield poplar cultivation, the orientation cultivation techniques of poplar short rotation were systematically summarized.
