摘  要:
在天目山自然保护区对毛竹在2008和2009年的高生长及2009年的竹蔸、叶、秆、鞭和笋5个器官的含水率进行了测定。结果表明,在大、小年的高生长(Pn)与出土生长时间(t)的关系均呈"S"形曲线;竹蔸的含水率范围为0.33~0.70,竹叶为0.32~0.63,竹秆为0.32~0.58,竹鞭为0.36~0.61,竹笋为0.46~0.90,其中竹笋含水率最高,变化也最大,其次是竹蔸、叶、鞭和秆;毛竹地下部分的含水率范围为0.34~0.62,地上部分为0.33~0.57。

摘  要:
The height growth of bamboo in 2008 and 2009 as well as the water contents of bamboo stump,leaves,straw,rhizome and in 2009 were measured at the Tianmu Mountain Nature Reserve.The results revealed that,the relationship between the height growth(Pn) and growth time(t) showed S-shaped curve in the two years;the water contents of bamboo stump,leaf,straw,rhizome and bamboo shoot were 0.50-2.31,0.46-1.80,0.50-1.38,0.56-1.58 and 0.89-8.96,respectively.In which,the water content of bamboo shoot was the highest and noticeable changed,follow by bamboo stump,leaves,rhizome and straw in order.The water contents of the underground and aboveground parts respectively were 0.34-0.62 and 0.33-0.57.
