林木引种驯化,包括外来树种的迁移种植以及本地树种的野生变家种。引种不同地带的栽培树种,在适应新地区的气候以后,很快就可以投入生产,成为新地区的栽培树种,如世界产材最多的松树(Pinus)、杨树(Populus)、桉树(Eucalyptus)三大属树种,在国际上已广为引种。本地的野生树种转为人工栽培,虽然不存在气候带的适应问题,但这类树种长期生长在天然林里,对土壤水肥、光照、空气湿度等生态因子的
Forest introduction and domestication, including the migration of alien species and wild species of native species. The introduction of cultivated species from different regions can be put into production soon after adapting to the climate of the new region. It is a species cultivated in the new region, such as Pinus, Populus, Eucalyptus, Three major genus species, has been widely introduced in the world. Although the local wild tree species have been changed to artificial cultivation, there is no climate zone adaptation problem. However, such tree species have been growing in natural forests for a long period of time. They have a long-term effect on ecological factors such as soil water and fertilizer, light and air humidity
