摘　　要：通过对日本落叶松2年生苗木采取不同越冬方法以研究不同越冬方法对日本落叶松苗木质量的影响,结果表明:采取全埋越冬法,质量最优,能降低苗木的损失率,提高苗木的抗旱能力,减少苗木含水量的消耗,正常维护苗木体内营养物质的循环,提高造林成活率。Through different overwintering methods on 2-year-old Larix kaempferi,the effects of different overwintering methods on quality of Larix kaempferi seedlings were studied.Result shows that adopting the method of buried in the earth for overwintering can obtain the optimal quality,reduce the rate of loss of seedlings,improve the drought resistance of seedlings,reduce the consumption of water content of seedlings,maintain loop of nutrition material in seedlings,improve the survival rate.
