摘　　要：为解决东北槭小苗生长缓慢成材周期长,寻求促进其生长的途径,采用温室培养的方法,以一年生东北槭小苗为受体,通过高生长量、叶长、叶宽、冠幅、地上鲜重、地下鲜重及叶绿素含量、POD活性的测定,研究茶条槭、元宝槭凋落叶及假色槭和东北槭混合凋落叶粉碎物对东北槭小苗生长的影响。结果表明,茶条槭凋落叶对东北槭表现出了“低促高抑”的化感作用,当添加量最大120g/10kg时,小苗受到抑制。元宝槭凋落叶添加量最大时各指标促进作用显著,东北槭高生长量增加了1倍。混合凋落叶对东北槭生长无明显作用。In order to solve the problem of slow growth of Acer mandshuricum and long growth period,the ways to promote their growth were sought.Using the method of greenhouse cultivation,the annual seedlings of Acer mandshuricum were used as receptors,the effects of growth of Acer mandshuricum seedlings add leaf litter of Acerginnala et.were studied by means of high growth amount,leaf length,leaf width,crown width,fresh weight above ground,fresh weight below ground,chlorophyll content and POD activity.The result shows that leaf litter of Acer ginnala showed an allelopathic effect of“low concentration promotion and high concentration inhibition”on A.mandshuricum.When the maximum dosage was 120g/10kg,the seedlings were inhibited.When the leaf litter of A.truncatum was the largest,the promoting effect of each index was significant,and the height growth of A.mandshuricum was doubled.Mixed leaf litter had no significant effect on the growth of A.mandshuricum.
