摘　　要：研究比较了大型丛生竹种车筒竹带蔸埋秆、埋单节、埋双节和主枝扦插法的育苗效果,通过分析4种育苗方法的出苗率、成竹率和成竹质量等指标,认为,埋双节法效果最好,出苗后基本全部成竹,成竹率达97.9%,育苗1年后新竹平均竹高达2.0 m,平均地径1.48 cm。另外3种方法,各有优劣,带蔸埋秆法尤其是母竹基部的成竹质量较好;主枝扦插法材料丰富、费用低,通过条件控制提高其成竹率,亦有较大开发潜力。Propagation methods of burying culm with rhizome, and main branch cutting of Bambusa sinospinosa were studied. survival rate and new bamboo quality of the four methods were 1-node section, 2-nodes section The seedling emergence rate, compared. The results showed that the 2- nodes section burying method had the best propagation effects, its seedling survival rate amounted to 97.9%, and one year later, the average height and diameter of new bamboos reached 2.0m and 1.48cm respectively. The other three methods had their advantages and disadvantages, and through burying culm with rhizome, the new bamboo quality was better especially around the parent shoot base. Nevertheless, the main branch cutting method allowed plenty low cost materials, if its seedling survival rate could be raised through controlling the propagation conditions, this method would have great potentials.
