新疆杨引入我省已有十多年历史。经各地试种,生长表现良好,具有抗性强、生长快、材质好、树冠美观和不易遭受虫害(蚜虫)等优点。群众乐意栽培,是四旁绿化,营造农田防护林的好树种。由于插枝繁殖生根困难,当年成活差、长势慢,跟不上造林需要,影响了生产进度。各地曾用壮条迟插、扩大采穗圃和秋插培垄等措施,提高了一些繁殖指数,但苗木
Xinjiang Yang introduced into our province for more than 10 years of history. After planting around, good growth performance, with strong resistance, fast growth, good material, beautiful canopy and are not susceptible to pests (aphids) and so on. The masses are willing to cultivate, which is a good tree planting around shelterbelts on all sides.

However, seedlings
