摘要
通过对料慈竹百日苗生长发育规律的研究结果表明:(1)百日苗木高生长可用方程Y=-18.24+1.07t+0.01t2+5.4×10-0.5t3来拟合,呈相关性显著;(2)百日苗的地径不随高生长增高而增粗,而是生长到一定时期不再生长;(3)当幼苗高生长基本结束后,侧芽开始从秆基萌发,长出分蘖苗,分蘖苗逐次加粗;(4)百日苗主根的生长较强,一级、二级侧根生长较少,此时不宜进行造林。
The study on growth and development rules of 100-days seedlings of Bambusa distegia shows that： （1） The height growth of 100-days seedlings was fitted with the equation of Y=-18.24＋1.07 t＋0.01 t^2＋5.4 × 10^-0.5 t^3 which reached significant correlation; （2） The ground diameter of 100-daysseedlings didn＇t grow following the growth of height, while in a certain time, the ground diameter grew no longer; （3） When the height growth of the seedlings finished, lateral buds started to sprout to grow tiller seedlings, which grew from the stem base and was thicker and stronger than genotypic; （4） Although taproots of 100-days seedlings were developed, the lateral roots are less, so the seedlings in this period was unsuitable for afforestation.
