摘　　要：以我国最大的东方杉成年片林、大胸径散生大树、水湿地群落和2～3年生的东方杉幼树为材料,对东方杉优树选择标准、优树无性系构建和筛选技术进行了探讨,并通过田间观察、比较和评价,初步选出了11个具有特色的东方杉优树无性系,其中7个为速生优树无性系,3个为耐碱优树无性系,1个为景观优树无性系。Our country＇s the largest forest, scattered large-diameter adult trees, water wetland communities and 2 - 3-year-old saplings of Taxodium mucronaturn × Cryptorneria fortunei were used as materials, the selection criteria for the plus trees and the establishing method and screening tech- nique for the plus tree clones were studied,and 11 distinctive clones of the plus trees,including 7 fast growing clones,3 alkali-tolerant clones and a landscape clone, were preliminarily selected through field observation, comparison and evaluation.
