Abstract: The randomized block design was used to study the relationship between stand density and shoot yield of Phyllostachys praecox.Cutting the tail could improve the shoot output,with reserve 1/3 of the bamboo tail,the shoot yields of the bamboo is the most,and its economic performance is best.

Key words: Phyllostachys praecox, tail length, shoot output

摘要： 采用随机区组试验设计法对雷竹保留尾梢长度与笋产量的关系进行研究,通过对比分析表明,钩梢比不钩梢的笋产量高,其中以保留竹尾长度1/3的笋产量最高,经济效益最好。
