摘要:
 为评价青梅苗木质量，应用相关分析确定苗高和地径作为青梅苗木分级指标，采用逐步聚类和平均值(M)±标准差(SD)法探究青梅苗木分级标准，比较分析2种方法各级别苗木的造林效果，从而确定适宜的分级方法和分级标准。结果表明，采用地径(D)、苗高(H)作为2年生青梅苗木分级指标是可行的；从各级别苗木比率以及造林效果分析，青梅苗木适宜采用平均值±标准差法进行苗木分级，其分级标准为Ⅰ级苗H≥45.3 cm，D≥4.7 mm；Ⅱ级苗21.8 cm≤H＜45.3 cm，3.3 mm≤D＜4.7 mm；Ⅲ级苗H<21.8 cm，D<3.3 mm。
Abstract:
 In order to evaluate the quality of Vatica mangachapoi seedlings,seedling height and root collar diameter were screened out as indexes for seedling grading by correlation analysis,and seedling grading standards were studied by gradual clustering analysis and mean ±standard deviation methods,and planting effectiveness were compared for seedlings graded by both methods,thus suitable grading method and standard were determined.The results showed that it was practicable to use root collar diameter and seedling height as indexes for grading of two-year-old V.mangachapoi seedling; mean ±standard deviation method was better than gradual clustering analysis and was more feasible for seedling grading of this species at aspects of seedling ratio of all sorts of grades and planting effectiveness; and grading standard was as follows: seedlings with height no less than 45.3 cm and root collar diameter above 4.7 cm were classified as the first grade,those with height less than 45.3 cm and above 21.8 cm,and root collar diameter lower than 4.7 mm and above 3.3 mm belonged to the second grade,and those with height lower than 21.8 cm and root collar diameter below 3.3 mm to the third grade.
