摘　　要：为闽东地区森林景观彩化套种树种选择提供依据,以江西省庐山市种源的红翅槭幼苗为试验材料,研究不同杉木人工林郁闭度(0.4、0.6和0.8)对其林下套种的红翅槭幼苗生长和开花的影响。结果表明:(1)B处理(郁闭度0.6)最有利于促进红翅槭生长,其地径和冠幅生长量最大,分别达到1.95 cm和104.1 cm,显著高于处理A(郁闭度0.4)和处理C(郁闭度0.8),分别较二者提高7.1%、10.8%和10%、13.2%;(2)处理A则最有利于促进红翅槭开花,开花数量显著高于处理B和C,分别较二者提高43.5%和94.6%。在0.6郁闭度林分下套种的红翅槭,生长最快,并且开花情况表现良好,是比较适合红翅槭套种的林分密度。In order to provide basis for selecting intercropping tree species for forest landscape coloration in the eastern Fujian area,taking seedlings of Acer fabri originated from Lushan City of Jiangxi Province as the experimental materials,the effects of different canopy densities(0.4,0.6 and 0.8)of Chinese fir plantation on the growth and flowering of under-forest Acer fabri seedlings were studied.The results showed as the following two aspects.(1)Treatment B(canopy density 0.6)was the most conducive to promoting the growth of Acer fabri,with the largest increases in ground diameter and crown width reaching 1.95 cm and 104.1 cm,respectively,which was significantly higher than treatment A(canopy density 0.4)and treatment C(canopy density 0.8),with increases of 7.1%,10.8%and 10%,13.2%,respectively.(2)Treatment A was the most conducive to promoting Acer fabri to bloom,and the number of flowers was significantly more than that of treatment B and treatment C,increasing by 43.5%and 94.6%,respectively.Acer fabri intercropped under the forest of 0.6 canopy density showed the fastest growth and good flowering performance,and it was the more suitable stand density for intercropping Acer fabri.
