摘　　要：雷竹、早竹、白哺鸡竹、红竹等为我国优良笋用竹。1997年元月桐梓县在不同海拔作引种试验,经对不同竹种的造林成活率、发笋率、笋期及生长节律的观测，并作生长量的统计分析；还对退笋与竹株死亡原因分析。从而为不同竹种选择适生地与合理经营提供初步的依据。试验结果表明，不同竹种在不同海拔的适宜性排序为：海拔1400m处，早竹＞红竹＞雷竹＞白哺鸡竹海拔1100m处。Phyllostachys praecox, Ph. iridenscence,Ph. dulis are fine shoot bamboo in China. They were introduced to Tongzi region in different altitudes. Observations on their survival rate,shooting rate,shooting period and growing rhythm were made, including statistical analysis on their growth as well as causes of shoot degrading. Therefore, the preliminarymeasures are provided how to choose suitable places and reasonable management for variousbamboo. Trial results show adaptibility of various bamboo in different altitudes is in order asfollows:Altitude 1400m: Ph. praecox>Ph. iridenscen>Ph. dulisAltitude 1100m: Ph. dulis>Ph. iridenscen>Ph. praecox
