包头市银中杨、垂爆柳引种造林试验

Experiment of Introduction and Afforestation on Populus alba × P. berolinensis and Salix × ‘chuibao'in Baotou

包头市从1994年开始引种银中杨、垂爆柳,1997年将银中杨、垂爆柳进行造林试验,选择杂交杨、新疆杨、河北杨与银中杨进行对照观测;旱柳作为垂爆柳的对照。在1997-1999年和2013年对树木生长量、抗病虫害能力和抗逆性能进行实地监测分析。结果表明:银中杨在包头地区引种造林后生长良好,适应包头市南部平原及周边地区的生态环境,充分显示出极强的抗逆、速生等特性,可以大力推广,在当地生态建设工程中具广阔的应用前景。垂爆柳造林后在当地生长表现良好,但染虫害严重,抗逆性较差,保存率低,在当地推广造林适应性较差。

Abstract：Populus alba × P. berolinensis and Salix×chuibao have been introduced in Baotou since 1994, and the afforestation test were done in 1997, with choosing Populus hopeiensis Hu et Chow, Populus alba var. pyramid- alis Bunge and Salix matsudana Koidzh as the control. The DBH, height, pest resistance and stress resistance have been monitored and analyzed in 1997 - 1999 and 2013. The results show that Populus alba × P. berolinensis grow well and fully adapt to the ecological environment of Baotou. It can be promoted widely in the ecological engineer- ing for this area. But Salix x chuibao has low resistance with poor adaptability in Baotou.
