摘要
以锡林郭勒盟正蓝旗丘间地筐柳天然林为研究对象,根据该灌木树种的生长特性,在盖度30%以上、母株基径19.73 mm以上的筐柳林地,于冬末至翌春平茬,平茬周期为7~9年,平茬方式为机械带状平茬,留茬高度0~5 cm,平茬带宽20 m,保留带宽120~160 m,逐年循环进行。通过平茬能够解决筐柳林多年不平茬出现的生长衰退、干枯死亡问题,明显地延长平茬周期,大幅度降低抚育成本,保持筐柳林的正常生长和健康。
Abstract：Taking the natural forest of Salix linearistipularis in lowland among dunes in Zhenglan Banner, Xilinguole League as research object, the forestland of Salix linearistipularis, with coverage over 30% and basal diameter of mother plant over 19.73 ram, has been stumped from later winter to next spring, the stumping period is 7 - 9 years, the stumping method is mechanical zonal stumping, the wide of stumping is 20 m, the reserved bandwidth is 120 -160 m, and the stumping should be circled year by year. The stumping can prevent the growth declination, withering and death of Salix linearistipularis, prolong the stumping period obviously, decrease the tending cost greatly and keep the normal growth.
