摘　　要：利用丛生竹竹腔壁具有吸收功能,以撑绿竹为研究对象,采用不同浓度的尿素和磷酸二氢钾进行竹腔施肥,探索丛生竹高效施肥技术。结果表明:1.0%的磷酸二氢钾能提早出笋7d左右;分别施用0.5%、1.0%的尿素和磷酸二氢钾明显增加撑绿竹出笋数量,0.5%、1.0%的尿素以及0.5%的磷酸二氢钾对撑绿竹胸径生长有显著的影响。Based on the absorptive function of the cavity wall of sympodial bamboo, this paper takes Bambusa pervariabilis×Dendrocala mopsisgrandis to conduct the cavity-injecting fertilization with different concentrations of CO（NH2）2 and KH2PO4.The result showed that 1.0% KH2PO4 can facilitate shooting seven days earlier, the different concentrations of CO（NH2）2 and KH2PO4 （0.5% and 1.0%） can increase obviously the number of shoots, and 1.0% KH2PO4 as well as both 0.5% and 1.0% CO（NH2）2 can increase the DBH of the bamboo culm.
