摘　　要：笔者以3个种源地的五角枫幼苗为试验材料,研究不同浓度氮沉降对五角枫幼苗生长的影响。结果表明,氮沉降对不同种源地五角枫幼苗的苗高、地径、全株生物量、地上生物量、根生物量、茎生物量、叶生物量均可造成明显的影响。在一定范围内,氮沉降浓度增加可以促进五角枫幼苗的生长;但当氮沉降浓度高于某一值时,则会对其生长产生负面影响。The effects of different nitrogen deposition concentration on Acer mono Maxim. seedlings were studied with 3 different provenances of Acer mono Maxim. seedlings as test material. Results showed that nitrogen deposition had obvious effects on the seedling height, ground diameter, whole plant biomass, aboveground biomass, root biomass, stem biomass, leaf biomass of Acer motto Maxim. seedlings. In a certain range, the increase of nitrogen deposition concentration could promote the growth of Acer mono Maxim. seedlings. But when the nitrogen concentration was higher than a certain value, it would have a negative impact on the growth of Acer motto Maxim. seedlings.
