摘　　要：对茶秆竹笋期生长情况和鞭根系统与出笋关系的观察调查得知 ,茶秆竹出笋初期 1 0d内为出笋早期 ,1 0～ 2 5d为出笋盛期 ,2 5～ 40d为出笋末期 ;竹木混交林较纯林可相应推迟出笋各期 ;早、盛期的退笋低 ,成竹较高 ;幼竹高生长呈现慢—快—慢 3个阶段 ;隔天采笋可增加出笋数量 ,有利于茶秆竹作为笋用林的培育 .Through the observation on the growth rhythm of bamboo shoots of Pseudosasa amabilis and on the relation between rhizome system and shooting,the results show that the shooting period can be divided into three stages.The duration of the first 10 days belongs to the initial stage,the duration from 10th～25th days is the boosting stage,and the duration from 25th～40th days is the terminal stage.The rate of degenerated shoots in early stage and in boosting stag is lowed,while the rate of growing up into bamboo is higher.The amount of shooting can be increased by unearthing shoot every other day.The height-growth rhythm of bamboo is firstly slower and then become faster,at last get slower again.
