摘　　要：为探讨多花山竹子林下栽培种植技术,选择1 a生多花山竹子优良容器培育实生苗,在福建省洋口国有林场市郊试验站龙船山樟树林下开展不同坡位和光照强度(郁闭度)两个生境因子造林对比试验,并在造林4 a后对多花山竹子的生长性状进行调查分析。结果表明:不同坡位对各生长性状的影响的差异极具统计学意义,在树高、地径和侧枝量性状上表现为下坡位>中坡位>上坡位,生长性状间的影响表现为地径>侧枝>树高,而对其成活率的影响不明显;不同光照强度(郁闭度)对其树高、地径和侧枝量的影响存在显著差异,影响表现为6700~8200 lx(中)(郁闭度约0.7)>7800~8500 lx(郁闭度约0.5)(强)>5500~6500 lx(弱)(郁闭度约0.9),而对其成活率的影响差异极具统计学意义,其最高与最低分别为96.7%、85.2%,相差11.5个百分点。因此,在林下套种多花山竹子时,应选择郁闭度在0.7左右立地条件较好的中下坡位,才能取得理想的栽培种植效果。In order to discuss the cultivation techniques of Garcinia multiflora Champs,a contrast experiment was carried out,bying choosing annual Garcinia multiflora Champs to cultivate seedlings in fine containers under two habitat factors including different slope positions and light intensity(canopy density)in Camphor tree forests in Longchuan Mountain,an experimental station,locating on the outskirts of Fujian Yangkou State-owned Forest Farm,and a research analyzing the growth characteristics of Garcinia multiflora Champs after 4-year afforestation was launched.The results showed that different slope positions had obvious effects on various growth characteristics of Garcinia multiflora Champs.The influence of different slope positions on the growth characteristics including tree height,ground diameter and the amount of lateral branches was in the order of lower slope>middle slope>upper slope;The influence among various growth characteristics was in the order of ground diameter>the amount of lateral branches>tree height,while the influence of different slope positions on the survival rate of Garcinia multiflora Champs was not obvious.The effect of different light intensity(canopy density)on the growth of tree height,ground diameter and the amount of lateral branches was in the order of 6700 to 8200 lx(medium)(canopy density was about 0.7)>7800 to 8500 lx(canopy density was about 0.5)(strong)>5500 to 6500 lx(weak)(canopy density was about 0.9).While the light intensity has very obvious influence on the survival rate of Garcinia multiflora Champs with 96.7%(the highest)and 85.2%(the lowest)respectively,the gap was 11.5 percentage points.Therefore,when Garcinia multiflora Champs is interplanted in the forest,the middle and lower slope position with better site conditions(canopy density was about 0.7)should be selected to obtain the ideal cultivation effect.
