摘要
对村宅旁大叶榉中幼龄散生木采取立竿绑缚、合理留养树冠、树干皮层纵割促粗生长、加强病虫害防治等抚育措施,促使树木复壮,结果表明:采用立竿绑缚,可以增强榉树幼树主干直性,培养通直高大圆满的主干;枝下高1/3的单株高、粗生长均优于枝下高2/3、1/2时的高、粗生长,年均树高生长量达到53 cm、年均胸径生长量达到1.3 cm;经树干皮层纵割后,年均胸径生长量可达到0.93 cm,比对照年均胸径生长量增加0.3 cm。
Measures of binding the sapling to bamboo pole,crown pruning,longitudinal cut through the trunk bark,and strengthening pest control were taken on young half-matured scattered trees of Zelkova schneideriana near village.Result shows that： taking measure of binding the sapling to bamboo pole can strengthen straight of Zelkova schneideriana saplings to cultivate tall,straight perfect trunk;height width growth of clear bole height with 1/3 are all higher than that with 2/3 1/2;average annual height growth reach 53 cm,and average DBH growth reach 1.3 cm;after longitudinal cut through the trunk bark,the average annual diameter increment which reaches 0.93 cm is 0.3 cm higher than CK.
