| 摘 要： | 通过对引黄灌区沙地花棒林进行不同留茬高度的平茬试验,其新萌发枝条数和生长量有所不同：在新萌发枝条数目上,留茬高度5cm和10cm时较高,2cm和20cm较低;新生枝条生长过程中,其生长量与留茬高度成负相关关系。试验表明研究区花棒林适宜的平茬高度为2～5cm。

| Abstract: | The experiment of stumping of Hedysarum scoparium forest was carried out in Yellow River Divert-ing Irrigation Area.The results showed： the amount of new germinated branch and the growth increment of new-branch under different stumping height,when the stubble height is 5 cm and 10 cm,the amount of new germinated branch was higher than the stubble height is 2 cm and 20 cm,the growth increment of new-branch had obviously negative correlation with stubble height,the appropriate stubble height is 2～5 cm. |
