【摘要】 本文通过在四川平武王朗和卧龙自然保护区的25种大熊猫主食竹类引种试验,对不同海拔高度不同植被类型竹种的适应性与差异性进行了研究。重点观测分析了成活、保存、生笋、成竹率四项成效指标综合值及枝叶生长发育情况,并按综合值高低排列名次。三年筛选结果,在王朗引种效果较好的竹种是石棉玉山竹Yushanialineolata、青川箭竹Fargesza rufa、糙花箭竹F.Scabrida、冷箭竹Bashania fangiana,卧龙表现好的有缺苞箭竹F.denudata和石棉玉山竹Y.lineolata。引种地宜于0.5—0.7中等郁闭度的暗针叶林和桦木次生林下为佳;海拔和类型因素对竹种成活与生长都有明显影响。适应性强的种类具有喜湿耐酸耐低温的卷叶抗旱特性,既有不同程度的适应性,也有地区间与种间的差异性。更多还原

【Abstract】 In this paper, we discussed the adaptabilities of 25 bamboo species introduced into Wanglang and Wolong Reserves from differ- ent altitudes and forest types. The indexes included survival rate of first and second year, bamboo shooting rate, adult bamboo formed rate as well as average value of these four indexes. Based on the average value of 3 year observations we learnd that Yushania line- olata, Fargesia ruta, F. scabrida, bashania targesis, F. denudata and Y. lineolata grew well in Wanglang and were suitable to the environs of Wolong. They prefer the forestland with canopy densities of 0.5--0.7. The altitude was another factor affecting bamboo growth and survival. The bamboos having strong adaptabilites had characteristics of moisture-like, good tolerance to acid soil, low temperature and drought, but this varied from place to place and species to species.更多还原
