新疆杨自1998年引入康平地区以来,在造林地表现良好,以其耐盐碱,耐干旱、生长快、适应性强、树型美观等特点成为城乡绿化大面积推广树种。近几年生产上多采用嫁接方法繁育种苗,直接扦插成活率低,普遍在30％以下。我们于1999年进行催根栽植试验,取得较好效果,具体方法如下。 Xinjiang Yang since the introduction of the Kangping area in 1998, good performance in afforestation, with its resistance to salt and alkali, drought resistance, fast growth, adaptability, aesthetics and other characteristics of a large-scale urban and rural afforestation tree species. In recent years, the production of grafting methods to use more breeding seedlings, direct low survival rate, generally below 30%. We carried out the rooting test in 1999 to achieve better results, the specific method is as follows.
