摘　　要：探索狭叶方竹实生苗栽培的适宜性,为推广栽培提供借鉴。本研究通过露天和林下两种不同环境进行狭叶方竹实生苗栽培试验,并对实生苗的植苗成活率、出笋数量及其新发竹笋地径大小情况进行观察和测定。结果表明:在两种不同种植环境下,狭叶方竹实生苗植苗成活率、出笋数量有显著差异,林下环境植苗成活率高于露天环境,但两种环境植苗成活率均大于90%,满足造林成活率大于85%的标准要求;露天环境出笋数量高于林下环境,露天环境单株(丛)出笋数量最多可达110株,最少为15株;新发竹笋地径大小差异不显著。An optimal Chimonobambusa angustifolia seedling can promote the cultivation of narrow leaved bamboo.In this study,a series of experiments were conducted to cultivate the Chimonobambusa angustifolia seedlings under the open air and the forest.A systematic measurement was performed on the survival rate of seedlings,the number of shoots,and the diameter of newly sprouted bamboo shoots.The results showed that there was the significant difference in the survival rate and the number of shoots of Chimonobambusa angustifolia seedlings under two planting environment conditions.The survival rate of seedlings in the understory environment was higher than that in the open-air environment.Furthermore,the survival rate of seedlings in both environmental conditions was above 90%,fully meeting the standard requirement of 85%survival rate for afforestation;The number of shoots that produced in outdoor was greater than that in the understory,with the maximum of 110 shoots per plant(cluster)and the minimum of 15 shoots per plant(cluster)in outdoor environments;There was no significant difference in the diameter of newly released bamboo shoots.The finding can provide a strong reference to promote and cultivate the Chimonobambusa angustifolia seedlings.
