摘　　要：[目的]探究多穗柯矮化密植叶用林的经营效果。[方法]以株行距180 cm×180 cm传统密度营造的多穗柯林分为对照(CK),研究矮化密植(种植密度为6273株/hm^(2))对多穗柯的生长状况、鲜叶质量(嫩枝、嫩叶)、采摘工效等经营效果的影响。[结果]矮化密植处理的株数比CK处理增加117.4%,树高降低71.1%,枝下高较低,总分枝数略有降低,但5级及以上分枝数显著增加,鲜叶质量明显提高,两者间单株总鲜叶质量在0.05水平存在显著差异,单位面积鲜叶质量在0.01水平存在显著差异。矮化密植林分站立采摘率达100%,而CK的站立采摘率仅30.4%~31.5%,矮化密植处理采摘速度较CK处理提高3倍多。[结论]采用矮化密植技术措施处理多穗柯叶用林具有良好的经营效果,可以在适当的地区推广应用。[Objective]To study the management effect of dwarf dense leaf plantation of Lithocarpus polystachyus.[Method]The row spacing 180 cm×180 cm stand was used as control to study the effects of dwarf dense planting(planting density of 6273 plants/hm^(2))on the growth status,fresh leaf quality(twigs and leaves),picking efficiency and so on.[Result]Compared with CK treatment,the number of plants in dwarf dense planting treatment increased by 117.4%,the tree height decreased by 71.1%,the height under branches was low,and the total number of branches decreased slightly,but the number of branches of grade 5 and above increased significantly,and the quality of fresh leaves was significantly improved.There was a significant difference in the total fresh leaf quality of a single plant at the level of 0.05 and the fresh leaf quality of a single area at the level of 0.01.The standing picking rate of dwarf dense planting stand was 100%,while that of CK was only 30.4%-31.5%.The picking speed of dwarf dense planting treatment was more than 3 times higher than that of CK treatment.[Conclusion]The dwarf dense planting technique has good management effect and can be popularized in appropriate areas.
