| 摘 要： | 笔者对钟祥市1a生紫薇扦插苗进行随机抽样调查,在调查苗木地径、株高等生长性状基础上,采用平均值±标准差方法和逐步聚类法进行苗木等级检验,最终确定紫薇1a生扦插苗分级标准为：I级苗地径≥0.90cm,苗高≥120.0cm;Ⅱ级苗地径0.50－0.90cm,苗高80.0－120.0cm。 |

| Abstract: | The Cutting seedlings of Lagerstroemia indica L.which are cultivated 1-year old in Zhongxiang City in Hubei.are investigated by random sampling.The growth character of basal diameter rand height are investigated,used the X-±S method and the gradual clustering method for testing the seedling grade,Based on productive practice,the authors concluded the classification of 1-year old Lagerstroemia indica L.cutting seedlings grading standard,the ground diameter and height of the I grade seedling are bigger than 0.90 cm and 120.0 cm respectively,and those of the II grade seedlings are 0.50 ～0.90 cm and 80.0 ～120.0 cm respectively. |
