茶秆竹竹鞭生长规律的研究

通过对茶秆竹鞭系结构的研究 ,结果表明 ,茶秆竹鞭系结构较为合理 ,鞭系以介于 4～ 8m的中型鞭为主 ,幼壮龄鞭段主要分布在 0～ 30 cm的土层中 ;2～ 4级的鞭系占 5 1.9% ,二侧分叉的鞭段数占优势 ,随着鞭龄的增大 ,分叉趋于复杂 ;竹林以壮、中龄鞭为主 ,鞭龄与鞭级呈反相关 ;鞭芽的死亡率较高 ,壮龄鞭的成竹率可达 2 6 .2 5 %。据此 ,控制竹林密度 ,调节鞭系结构 ,清除老鞭 ,提高壮、中龄鞭比例是竹林抚育的关键措施

Study on the Bamboo Scourge Growth Regularity of Pseudosasa amabilis McCl.

Based on the bamboo scourge system structure of Pseudosasa amabilis McCl . The result showed that the system structure is reasonable; the length of middle scourge is 4 8m and the scourges are mainly in 0 30cm layers; the proportion of 2 4 scales bamboo scourge system is 51.9% and the forks are more complex as the age increases. The main scourge is middle and able bodied age and the age is reverse to the scale. The death rate of buds is high and the rate of able bodied scourges should become bamboo could reach 26.25%. So the density, systems and ages are very important to the bamboo forestry.
