摘　　要：本文通过对四季竹地下鞭根系统的调查表明：四季竹地下鞭根系统主要集中在0—20cm深的土层中，为浅鞭系竹种；1-2年生休眠芽中活芽的比例最多，2”4年生竹鞭萌发芽最多，5年生及以上竹鞭几乎没有发笋能力。因此在竹林培育管理中主要是搞好0-20cm土层工作，使其多发鞭，多出笋，对于5年以上的竹林要及时挖掉老鞭和竹蔸。The investigation on growth rule of rhizome and lateral buds ofOligostachyum lubricum （wen） King f. showed that the rhizome grows in shallow soil layer, mainly distributed at 0-20 cm deep soil layer. Among the 1-2-year --old dormant shoots, living shoots took a higher share and the 2-4- year-old rhizome generated the most shoots, but the 5-year-old rhizome can generate little shoots at all. Therefore, in cultivation and management of bamboo forests, it shall focus the management of the 0-20 cm deep soil layer to promote the shoot yield. And it shall dig out in time the old rhizome of the bamboo forest at age of 5 and above.
