胡杨是一种耐盐碱、耐干旱、抗风沙的杨树,是西北地区沙漠地带和盐碱地重要的造林树种之一,目前存在的种群数量越来越少。为了扩大胡杨种群数量,首先要解决胡杨苗木繁育问题。目前用种子繁殖的方法已经成功,但满足不了造林需求。我们采用容易成活的新疆杨作砧木嫁接胡杨的新方 Populus euphratica is a salt-tolerant, drought-resistant, sand-resistant poplar, which is one of the important afforestation species in desert areas and saline-alkali lands in Northwest China. There are fewer and fewer existing populations. In order to expand the population of Populus euphratica, we must first solve the problem of poplar nursery stock breeding. The current method of seed breeding has been successful, but can not meet the needs of afforestation. We use the new poplar rootstocks that are easy to survive in Xinjiang
