摘　　要：以丛生竹新品种佯黄竹(Bambusa changningensis Yi et B.X.Li)为选育对象,以竹材产量高、浆(材)用品质好为选育目标,对佯黄竹4个无性系进行对比试验。结果显示:无性系YHZ03各项指标表现较好,栽植后3年即可正常投产,单株平均发笋量为5.4株,新生竹平均胸径6.50 cm、平均秆高13.20 m、平均秆质量8.60 kg/株;制浆造纸性能优于当地其他竹种,且具有区域适应性强、性状稳定、抗寒性较强等特点,在川南海拔1000 m以下地区适宜推广种植。With the high yield of bamboo and quality of pulp as the target and principle,4 clones of Bambusa changningensis Yi et B.X.Li are selected for the comparative experiments.The results show that the clone of YHZ003 has better performance for all indicators.It can be put into production 3 years after planting,with the average shoots of a single plant at 5.4,the average DBH at 6.5 cm,the average culm height at 13.2 m and the average culm weight at 8.6 kg;its property for pulping and papermaking is also better than other local bamboo species,with strong regional adaptability,stable characters and strong cold resistance.In this sense,it is suitable to be planted in the area below the altitude of 1000 m in South Sichuan.
