新疆杨耐寒耐旱,较耐盐碱,生长迅速,主干端直,材质优良,树冠美观(塔形),是南疆农田林网和四旁绿化的优良树种之一。 但是,新疆杨的苗木一直采用扦插繁殖,由于成活率低,加上扦插需要大量种条,因母树少,种条不足,大大影响了新疆杨的发展。
Xinjiang Yang cold and drought-tolerant, more resistant to salt and alkali, rapid growth, trunk straight, good material, beautiful tree (tower), is the southern farmland forest network and green trees around one of the fine species. However, Xinjiang Yang seedlings have been using cutting propagation, due to low survival rate, with cutting requires a large number of species, due to fewer trees, lack of species, greatly affected the development of Xinjiang Yang.
