| 摘 要： | 为促进柠条林人工更新和提高其利用率,文章对24年生灌木状柠条人工林进行0 cm、5 cm、10 cm 3种留茬高度处理.结果表明:(1)柠条再生能力较强,第1次平茬后新生枝株高,冠幅迅速增长,且能保持良好的生长状态,生物效益显著.(2)离地面10 cm平茬处理的效果优于其余2种处理.

| Abstract: | In order to promote regeneration & utilization of C.korshinskii,24-year-old C.korshinskii were treated with three stubble heights at 0 cm,5 cm & 10 cm.Result shows that:(1) the regeneration ability of C.korshinskii is stronger;after stump for the first time,the height & crown of C.korshinskii which can maintain good growth state,increase rapidly;(2)the effect of stump treatment(10 cm from the ground) is optimal than that of the rest two treatments. |
