Research on Sowing and Seedling Cultivation Technology and Seedling Grading Standards of Semiliquidambar Cathayensis
In order to master the sowing and seedling raising techniques and seedling quality classification stand-ards 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;Grade Ⅱ:D ≥0.37 cm,H≥50.7 cm;Grade Ⅲ:D<0.37 cm,H<50.7 cm.
