日本红枫原产日本,我国引种已多年。落叶小乔木,高可达5～8米,叶小而密,蜡质有光泽,叶片五裂,猩红色。喜温暖湿润气候及肥沃湿润而排水良好的中性和微酸性土壤,碱性土壤中生长不良,能耐-8℃低温。生长速度快,芽接苗按标准苗床规范养护3年,干径可达3厘米,5年可达5厘米以上,比国产红枫生长快1倍以上。国产红枫叶是暗红色,两者相比有明显差异。日本红枫牛长快的原因是:(1)春季萌芽比国产红枫早30天;(2)夏季在40℃高温下继续生长,且不灼伤嫩叶,国产红枫夏季叶片易被灼伤而停止生长.处于半休眠状态;(3)落叶比国产红枫晚20天。
Japan Hongfeng native to Japan, China has introduced for many years. Deciduous tree, up to 5 to 8 meters, the leaves are small and dense, waxy and shiny, cracked leaves, scarlet. Hi warm and humid climate and fertile and well-drained neutral and slightly acidic soil, poor growth in alkaline soil, capable of -8 ℃ low temperature. Rapid growth, Bud seedling standard seedbed conservation according to the standard 3 years, dry diameter of up to 3 cm, 5 years up to 5 cm above, more than double the growth of Chinese Maple. Domestic red maple leaves are dark red, there are significant differences between the two. Japanese red maple long cattle fast because: (1) the spring germination than the domestic red maple early 30 days; (2) the summer continued growth at 40 ℃ under high temperature, and does not burn the leaves, the summer leaves of domestic red maple easily burns Stop growing in a semi-dormant state; (3) deciduous Hongfeng late 20 days.
