摘要: 为促进山苍子产业高质量和规范化发展,随机选取50株山苍子[Litsea cubeba (Lour.) Pers.]种苗进行调查,采用相关分析确定苗木分级指标,通过逐步聚类分析法进行修正,计算出山苍子种苗的苗木分级标准。结果表明,以基径和株高作为山苍子种苗的质量分级指标,并得出其分级标准。Ⅰ级种苗:基径≥8.75 mm,株高≥83.8 cm;Ⅱ级种苗:6.28 mm≤基径<8.75 mm,69.6 cm≤株高<83.8 cm;Ⅲ级种苗(不合格苗):基径<6.28 mm,株高<69.6 cm。所抽取的50株山苍子种苗中,I、II级种苗(合格苗)占28%,III级种苗(不合格苗)占72%。

Abstract: In order to promote the high-quality and standardized development production of Litsea cubeba (Lour.) Pers., 50 seedlings were randomly selected for investigation. Correlation analysis was used to determine the grading index of Litsea cubeba (Lour.) Pers., and the grading standard of Litsea cubeba (Lour.) Pers. seedlings was calculated by gradual clustering analysis. The results showed that plant base diameter and plant height were used as the quality grading indexes of Litsea cubeba (Lour.) Pers. seedlings, and the grading standard was obtained. Grade I seedlings: Plant base diameter ≥ 8.75 mm, plant height ≥ 83.8 cm; Grade II seedlings: 6.28 mm ≤ plant base diameter < 8.75 mm, 69.6 cm ≤ plant height < 83.8 cm; Grade III seedlings (unqualified seedlings): Plant base diameter < 6.28 mm, plant height < 69.6 cm. Among the 50 Litsea cubeba (Lour.) Pers. seedlings extracted, 28% were grade I and II (qualified seedlings) and 72% were grade III (unqualified seedlings).

Key words: Litsea cubeba (Lour.)Pers., seedlings, grading standard, correlation analysis, gradual cluster analysis
