为了保证日本落叶松造林后林相整齐,减少苗木分化,提高林分质量,确保尽快郁闭成林。2009～2011年间,开展了苗木分类造林对比试验。结果表明：无论用哪个类别的苗木造林其成活率和保存率没有太大区别;造林后连续3 a地径、树高新生长依次为：1 a生超级苗〉2a生Ⅰ级苗〉2 a生混合苗〉2 a生Ⅱ级苗。造林时,一定将苗木进行分类,在2 a生Ⅰ级苗用完后,可采用1a生超级苗造林,不提倡混合苗造林。
為瞭保證日本落葉鬆造林後林相整齊,減少苗木分化,提高林分質量,確保儘快鬱閉成林。2009～2011年間,開展瞭苗木分類造林對比試驗。結果錶明：無論用哪箇類彆的苗木造林其成活率和保存率沒有太大區彆;造林後連續3 a地徑、樹高新生長依次為：1 a生超級苗〉2a生Ⅰ級苗〉2 a生混閤苗〉2 a生Ⅱ級苗。造林時,一定將苗木進行分類,在2 a生Ⅰ級苗用完後,可採用1a生超級苗造林,不提倡混閤苗造林。

The test of seedling differentiation and afforestation was carried out from 2009 to 2011,which aimed to ensure orderly forest forms after afforestation of Larix kaempferi,to reduce seedling differentiation,to improve the quality of forest stand,and to ensure forest establishment as soon as possible.The results showed that no matter which category of seedlings were used,the survival rate and the preservation rate had little difference.After afforestation,the ground diameter and seedling growth of 1-year old super seedlings were the highest,and that of 2-years old secondary seedlings were the lowest.In addition,the ground diameter and seedling growth of 2-years old first grade seedlings were higher than that of 2-years old mixing seedlings.Therefore,using mixing seedlings for afforestation shouldn't be advocated.Instead,seedlings must be classified.After 2-years old first grade seedlings were used up,1-year old seedlings could be used for afforestation.
