摘　　要：通过对麻竹等4个丛生竹种的田间育苗试验和撑绿竹等4种丛生竹种的大田生产观 测表明:丛生竹分株留蔸育苗与带蔸埋秆育苗,竹苗产量和苗木地径差异达显著至极显著 水平。前者可比后者平均每丛增产苗木28.0％-106.0％,竹苗平均地径大10.0％-54.0％。 分株留蔸育苗各竹种预留母竹数量和地径与当年竹苗产量和地径,除大头典竹外,相关性 均不显著。A comparison trial of seedling cultivation between four kinds of Dendrocalamus latiflorus and four kinds of Bambusa pervariabilis x Dendrocalamopsis grandis has been conducted in a separated individual and a buried cuttings. The result shows that both seedling productivity and ground diameter are all in extremely different levels. In separated individual, the productivity of seedling and the ground diameter is higher by 28.0-106.0% and 10.0-54.0% than in buried cuttings respectively. In addition, the relationship between the amount or size of parents and annual seedling productivity is not obvious in trial except Dendrocalamopsis bee-cheyana var. pubescens.
