根茬造林即将起出的苗木截去地上部分后留下的根茬埋入土中进行造林的方法。这种造林方法育苗时间短,造林过程比较简单,而且省工、节省费用,和其他无性繁殖一样,能保持亲本的优良性状,但要求造林地有较好的立地条件。当立地条件较差,尤其是地表温差较大,风沙危害严重又需加快造林速度的地区,这种造林方法是否实用, Root stubble afforestation Emerging seedlings truncated above the ground truncated part of the soil buried in the afforestation method. This afforestation method has the advantages of short seedling time, relatively simple afforestation process, and saves labor and saves costs. Like other asexual reproduction, it can maintain the excellent traits of parents, but requires better site conditions for afforestation. When the site conditions are poor, especially in the larger surface temperature difference, serious harm to the sandstorm and the need to speed up afforestation in the region, this afforestation method is practical,
