摘要
实心寒竹地下径复轴混生,灌木状,湖南特有竹种。对实心寒竹的生长调查表明:3月份气温回升后鞭梢开始生长,5-8月进入高峰期,12月至翌年2月基本停止;鞭芽萌发率幼龄鞭较低、壮龄鞭进入高峰期、老龄鞭随着鞭龄的增长而逐渐失去萌发能力;发笋数量盛期最大,初期次之、末期最小;出土竹笋的成竹率盛期最高,初期和末期相对较低;4月中旬开始换叶,每年换叶1次;竹秆高生长呈现"慢--快--慢"的生长规律。
The type of Chimonobambusa solida rhizome is amphipodium. It looks similar to shrub in the shape,which is endemic to Hunan.It grows in March with the temperature rising, enter the growth peak from May to Aug and stops its growth between Dec. and next Feb. The sprounding rate is low for young rhizome and at the peak for middle-aged rhizome while the old rhizome gradinglly loses its sprounding capality with the increase of age. The shooting number is the most in vigor period, then followed by that in initial and at the end period.The maturity rate of shoots is higher in vigor than that in initial and end period.Leaves change in the mid April, once in a year. The growth of bamboo culms follows the order of slow- fast-slow.
