摘　　要：红豆树1年生苗木质量评价标准为:Ⅰ级苗的临界值:总鲜重≥56.9 g,地径≥34.2 cm,苗高≥46.7 cm;Ⅱ级苗的临界值:56.9 g>总鲜重≥17.1 g,0.98 cm>地径≥0.67 cm,43.0 cm>苗高≥23.2 cm;Ⅲ级苗的临界值:17.1 g>总鲜重≥11.9 g,0.67 cm>地径≥0.56 cm,23.2 cm>苗高≥16.9 cm;Ⅳ级苗的临界值:总鲜重<11.9 g,地径<0.56 cm,苗高<16.9 cm。The quality evaluation standards of Ormosia hosiei annual seedling are as follows： the critical value of Ⅰ level seedling： total fresh weight ≥ 56.9 g, ground diameter ≥0.98cm, seedling height ≥42.99m; the critical value of Ⅱ level seedling： 56.9 g 〉 total fresh weight ≥ 17.1 g, 0.98 cm 〉 ground diameter ≥0.67 cm, 43.0 cm 〉 seedling height ≥ 23.2 cm; the critical value of m levd seedling： 17.1 g 〉 total fresh weight ≥ 11.9 g, 0.67 cm 〉 ground diameter ≥ 0.56 cm, 23.2 cm 〉 seedling height ≥16.9 cm; the critical value of Ⅳ level seedling： total fresh weight 〈 11.9 g, ground diameter 〈 0.56 cm, seedhng height 〈 16.9 cm.
