摘　　要：人工刺槐林经过2次轮伐后,逐渐失去培育价值,生态功能严重退化,亟须进行更新改造。由于刺槐根系萌蘖能力强,更新造林难度大,通过对比不同技术措施更新改造杜仲、侧柏,探讨了退化人工刺槐林相关改造技术。结果表明:与一般整地相比,全面整地可有效提高侧柏、杜仲成活率,增加两树种的生长量;全面整地+人工剔除刺槐树桩根系可有效地控制采伐迹地内刺槐萌条数量,改善更新苗木生长环境;与不平茬相比,平茬可有效提高杜仲成活率。After two rotations,the Robinia pseudoacacia plantation gradually loses its cultivation value;the ecological function is seriously degraded,and due to the strong germination ability of Robinia pseudoacacia roots,it is difficult to reafforest.This paper aims to explore the influence of different technical measures for the renewal and transformation of Robinia pseudoacacia plantation on the growth of Eucommia ulmoides and Platycladus orientalis,and to explore the related transformation technologies of degraded Robinia pseudoacacia plantation.The results show that compared with general finishing,mechanical comprehensive land preparation can effectively improve the survival rate of Eucommia ulmoides and Platycladus orientalis,and increase the growth of the two tree species.Mechanical comprehensive land preparation+manual removal of the root system and stump of Robinia pseudoacacia can effectively control the number of Robinia pseudoacacia buds in the harvesting site of Robinia pseudoacacia and improve the growth environment of seedlings.Compared with uneven stubble,flat stubble can effectively improve the survival rate of Eucommia ulmoides.
