雅安市撑绿杂交竹冻害调查分析

A Survey of Freezing Injury of Bambusa pervariabilis × Dendrocala mopsis grandis in Yaan

撑绿杂交竹是1998年从广西柳州引种到雅安的重要造林竹种之一。调查了经2004年冬季低温后雅安杂交竹的冻害情况,结果表明,杂交竹在雅安有不耐低温的局限性,但合理的栽植模式和抚育管理措施能在一定程度上缓解冬季冻害造成的危害及损失,仍是可发展的竹种之一。

Bambusa pervariabilis × Dendrocala mopsis grandis,which was introduced to Yaan from Liu Zhou,Guangxi Province in 1998,is one of the important forestation species. Its responses to the freezing temperature in the winter of 2004 in Yaan were checked in this paper. Our survey found that Bambusa pervariabilis Dendrocala mopsis grandis was limited by its cold sensitivity and was injured by the freezing temperature. However,proper planting pattern and management practices could be able to reduce the injuries and losses. Under proper management,Bambusa pervariabilis Dendrocala mopsis grandis is still a suitable bamboo species in this area.
