摘 要:本研究通过生长量对比法和形质综合评分法,初步制定了辽东栎优树选择标准。结果表明,LLSZ-3为优树。与优势木相比,该优树胸径、树高、材积的相对生长量为0.2、0.1和0.5;与平均木相比,该优树胸径、树高、材积的相对生长量为0.7、0.3和1.7。其各项形质指标的得分均不低于4分,且总分达到40分,可认定为优树。The preliminary criteria for selecting superior trees of Quercus liaotungensis were formulated through the growth comparison method and the comprehensive scoring method of form and quality.The results showed that LLSZ-3 was identified as the superior tree.Compared with the dominant wood,the relative growth of chest diameter,tree height and volume of timber of this superior tree was 0.2,0.1 and 0.5.Compared with the average wood,the relative growth of chest diameter,tree height and volume of timber of this young tree was 0.7,0.3 and 1.7.The scores of each of the form and quality indexes were not less than 4 and the total score reached 40,which could be recognized as a superior tree.
