红叶腺柳引种驯化研究

对红叶腺柳在11个引种试验地苗期生长量、苗木越冬、苗木顶端叶片呈色、物候特征及病虫害进行了研究,结果表明:辽宁沈阳、山西临汾、河南郑州、河南鄢陵、河南淅川、甘肃白银、新疆库车、宁夏灵武为红叶腺柳适宜引种栽培区,甘肃山丹马场、山西忻州、辽宁朝阳为不适宜引种地区。随着纬度的降低和海拔的降低,即平均气温越高、无霜期越长,芽开始膨胀时间、展叶期就越早,而高生长停止、主梢封顶期、落叶期到来的越晚;红叶腺柳1a生苗期在一些试验点有病虫害发生。

Introduction and Domestication of Salix chaenomeloides 'Variegata'

The adaptability of Salix chaenomeloides 'Variegata' was assessed in terms of its growth,over-winter,leaf color on seedlings terminal,phonological characteristics and pests and disease during seedling stage in 11 introduction trial sites.Results indicate that the areas adaptable for Salix chaenomeloides 'Variegata' growth are Shenyan in Liaoning,Linfen in Shanxi,Zhengzhou in Henan,Yanling in Henan,Xichuan in Henan,Baiyin in Gansu,Kuche in Xinjiang,Wuling in Ningxia;while the areas that are not adaptable for Salix chaenomeloides 'Variegata'are Shandan in Gansu,Xinzhou in Shanxi,Chaoyang in Liaoning.Buds and leaves started swelling earlier with decrease of latitude and elevation,i.e.with high mean temperature and long frost-free period.Meanwhile,its high growth and defoliation occurred later.There are pests and diseases that occur in some experimental locations.
