摘　　要：为掌握半枫荷播种育苗技术及苗木质量分级标准,为江西半枫荷主要栽培区苗木培育及检验提供理论依据,以赣州森源科技种苗场采集的半枫荷种子为试材,研究了半枫荷播种育苗技术,并以苗高和地径为指标,采用逐步聚类分析法研究了其1年生播种苗苗木质量分级标准。结果表明:半枫荷1年生播种苗可分为3级,即Ⅰ级苗:D≥0.53 cm,H≥68.4 cm;Ⅱ级苗:D≥0.37 cm,H≥50.7 cm;Ⅲ级苗:D<0.37 cm,H<50.7cm。In order to master the sowing and seedling raising techniques and seedling quality classification standards of Semiliquidambar cathayensis,and to provide theoretical basis for seedling cultivation and inspection in the main cultivation areas of Ganzhou province,the seeds of Semiliquidambar cathayensis collected from Senyuan scientific and technological seedling farm were used as test materials.The seedling quality grading standard of one-year-old Semiliquidambar cathayensis seedlings was studied by stepwise cluster analysis with seedling height and diameter as indexes.The results showed that the 1-year-old seedlings could be divided into 3 grades:Grade I:D≥0.53 cm,H≥68.4 cm;GradeⅡ:D≥0.37 cm,H≥50.7 cm;GradeⅢ:D<0.37 cm,H<50.7 cm.
