| 摘 要： | 黄甜竹笋用林生物量高达30375 kg/ha,地上和地下部分的比值变幅在1.2~1.5之间;杆的生物量最大,约为枝和叶的两倍;各器官含水量随年龄增加而减少;叶面积指数与其胸径、竹高、枝下高、冠幅相关,与植株年龄呈现抛物线关系;叶绿素含量除1年生外,随年龄增加而减少,且与叶片接受光照的程度有关,即接受光照越充分,叶绿素含量越高,但由于这些叶片生长较旺盛,衰老亦快,其叶绿素含量最终亦下降。

| Abstract: | The biomass of Acidosasa edulis bamboo shoot stand was as high as 30375 kg/ha.The above-ground and underground proportion of the biomass ranged from 1.2 to 1.5.The biomass of culms was twice as much as that of branches and leaves.The leaf area index (LAI) of A.edulis bamboo shoot-stand had a parabolic curve with the age of bamboo and was related to its diametcr,height,clear height and crown area.The chlorophyll content in leaves of A.edulis was negatively related to its age and positivelyto solar irradiance. |
