摘　　要：为探讨白木香(Aquilaria sinensis(Lour.)Spreng.)苗木质量分级标准,于白木香苗木主产区采集10批次1011株白木香实生苗为研究材料,测量10个主要的质量指标,进行描述性统计、相关性分析、主成分分析和K-聚类分析,结合苗木实际生产情况,对白木香苗木进行等级划分。通过分析并结合实际生产情况最终确定选取苗高、地径和分枝数3个指标作为等级划分的依据,将白木香苗木分成3个等级,最终分级标准为:Ⅰ级苗:苗高≥112 cm、地径≥11 mm、分枝数≥3,Ⅱ级苗:112 cm>苗高≥89 cm、11 mm>地径≥9 mm、3>分枝数≥2,Ⅲ级苗(不合格苗):苗高<89 cm、地径<9 mm、分枝数<2。最终的等级划分结果可用于白木香苗木质量分级标准的建立、区分苗木等级、排除不合格苗并对合格苗木进行定价,保证白木香产业规模化、专业化和规范化,并保障沉香资源可持续性发展。In order to investigate the grading standard of Aquilaria sinensis(Lour.)Sreng seedling quality,10 batches of 1011 seedlings of A.sinensis seedlings were collected from the main production areas of A.sinensis seedlings as the research materials,and 10 main quality indexes were measured.Meanwhile,the descriptive statistics,correlation analysis,principal component analysis and K-cluster analysis were carried out to classify the A.sinensis seedlings according to the actual production of seedlings.Through data analysis and combined with the actual production,three indexes of seedling height,ground diameter and branch number were finally selected as the basis for grading.The seedlings of A.sinensis seedling were divided into three grades,and the final grading standard was:Ⅰgrade seedling was identified as seedling height≥112 cm,ground diameter≥11 mm,branch number≥3,whileⅡgrade seedling was recognized as 112 cm>seedling height≥89 cm,11 mm>ground diameter≥9 mm,3>branch number≥2.And,Ⅲgrade seedling(unqualified seedling)was identified as seedling height<89 cm,ground diameter<9 mm and branch number<2.The final grading results could be used to establish quality grading standards of A.sinensis seedlings,distinguish seedling grades,exclude unqualified seedlings and price qualified seedlings,so as to ensure the scale,specialization and standardization of A.sinensis industry and ensure the sustainable development of A.sinensis resources.
