新疆杨为杨柳科杨属植物,乔木,高可达30米,主要分布在我国新疆地区。近年来,甘肃省武威地区大量引种育苗,其生长快、抗性强、经济效益高,在当地土壤干旱瘠薄、风大寒冷的条件下,比其他杨树生长快、病虫害少。但是,新疆杨繁殖能力较弱,繁殖系数较低,严重制约大面积育苗推广应用。近几年,笔者针对新疆杨扦插育苗摸索出了一些经验,阐述如下。
Poplar in Xinjiang is Poplar genus, trees, up to 30 meters high, mainly in China’s Xinjiang region. In recent years, a large number of seedlings were introduced in Wuwei area of Gansu province. They grow fast, are strong in resistance and have high economic benefits. Compared with other poplars, they grow faster and have fewer pests and diseases under the barren and windy conditions of the local soil. However, the reproductive capacity of Yang is weak in Xinjiang, and the breeding coefficient is low, which seriously hinders the popularization and application of seedlings in large area. In recent years, the author of Xinjiang Yang cuttings found some experience, described as follows.
