摘　　要：为选择马大相思(A.mangium×auriculaeformis)优良无性系推广应用于生产,开展5个马大相思无性系引种测试,对4年生无性系的适应性、速生性以及干形发育特征进行分析、评价与选择,结果表明:5个马大相思无性系的适应性、速生性和干形特征都比马占相思(CK)优异,其中马大相思中研10号和中研73号表现相对最优,4年生林分保存率达90%,树高、胸径、材积平均达8.55~8.84 m、9.44~9.84 cm和0.0315~0.0353 m^(3),而且抗风性也较强,干型基本通直圆满。其他无性系或是速生性不强或是干形开衩弯曲或是抗风性较差,暂不宜推广应用。In order to select excellent clones of A.mangium×auriculaeformis for promotion and application in production,five introduction tests of clones were conducted.An analysis,evaluation,and selection of the adaptability,rapid growth,and stem development characteristics of 4 a clones were conducted,and the results showed that:the adaptability,rapid growth,and dry form characteristics of the five clones of A.mangium×auriculaeformis are superior to those of A.mangium(CK).Among them,A.mangium×auriculaeformis Zhongyan No.10 and Zhongyan No.73 performed relatively best.The preservation rate of the 4-year-old forest stand reaches 90%,with an average height,diameter at breast height,and volume of 8.55~8.84 m,9.44~9.84 cm,and 0.0315~0.0353 m^(3),respectively.It also has strong wind resistance,and the dry type is basically straight and complete.Other asexual strains or those with weak rapid growth,dry branching and bending,or poor wind resistance are temporarily not suitable for promotion and application.
