| 摘 要： | 通过对7个月龄的猴耳环苗木分级标准的研究,采用随机抽样、逐步聚类分析等方法,对猴耳环苗木分级标准进行了初步探讨,提出了以苗高和地径作为分级标准的质量指标,得出了以下分级标准.Ⅰ级苗:苗高≥20.07 cm,地径≥0.48 cm;Ⅱ级苗:20.07 cm＞苗高≥15.13 cm,0.48 cm＞地径≥0.39 cm;Ⅲ级...

| Abstract: | The classification standard of seven months seedlings of Pithecellobium clypearia Benth.was studied by random sampling and the clustering gradually analysis.Height and diameter were proposed as the quality indices for grading.The results showed that height ≥20.07 cm and diameter ≥0.48 cm as Grade Ⅰ;20.07 cm> height≥15.13 cm and 0.48 cm>diameter ≥0.39 cm as Grade Ⅱ;height <15.13 cm and diameter <(0.39) cm as Grade Ⅲ. |
