象牙竹秆高5—7米,径3—7厘米,是一种中秆型竹种.该竹竹梢不下弯.中部最长节间长25—30厘米,秆环突出,箨环亦明显,因此节部较大.始笋期4月中旬,较同地淡竹笋期略早,较毛竹迟.据1982年观察,4月14日开始发笋,5月9日结束,笋期长26天.笋体棕绿色,秆箨稍厚,淡黄绿色,秆箨背面疏生黑褐色斑点.竹秆基部竹箨箨小叶基部宽1厘米左右,上部秆箨箨小叶皱折,箨舌短,有箨耳,长纤毛.竹叶长而狭,叶色较浓绿.笋期亦一边发笋一边换叶,要迟至8月份换叶全部结束.竹材劈裂性好,可破六层竹蔑供编织蓆条和箩筐,耐腐性强,故整秆用做水中竹簖.目前我省溧阳、宜兴有少量栽种,且生长良好,如溧阳横涧乡窑家边朱家一片林分
Ivory bamboo stalks 5-7 meters high, diameter 3-7 cm, is a kind of stalk type bamboo species. The bamboo shoots do not bend .In the middle of the longest internodes 25-30 cm, stalk ring prominent, ring is also obvious , So the Ministry of the larger section .SuspenseIn mid-April, compared with the same period of light bamboo shoot slightly earlier, than the bamboo late.According to the observation in 1982, April 14 began to shoot, May 9th, shoot 26 Day bamboo shoot body brown green, stalks slightly thicker, yellowish green, stalks sparse dark brown spots on the back of the bamboo stalks base bamboo 箨 箨 leaflet base width of about 1 cm, the upper stalk 箨 箨 leaflet folds, There are ear lice, long cilia.
