摘　　要：本文对马尾松苗期截报后根系形态结构的变化进行了测定分析，同时探讨其造林效果．结果表明：截根后主根顶端生长优势受抑制，侧须根发达，诱发了大量的菌根，根系的形态结构发生较明显变化．这种变化能够提高造林成活率，促进幼林的速生丰产．This paper analysed the changement of rooe system of masson pine after roots being cut during seedling stage, and further concerned its silvicultural effect, the results showed that the root shape changed evidently after root being cut, this changement would increase the survival rate and improve young tree grow fast.
