摘要

摘要: 选择白姜花、墨尔本姜花、青城姜花、红丰收、花叶山姜、春秋姜黄、广西莪术、紫花山柰和玫瑰闭鞘姜9 种姜科植物作为试验材料，研究其在不同光照强度处理下生长状况及形态观赏特性。通过对光响应曲线的测定，得出光饱和点、光补偿点等数据。根据各植物的光响应数据，结合实际养护观测经验，得出各植物适应的大致光照范围，为精细化管养和景观配置提供参考和借鉴。结果表明，花叶山姜等山姜属植物相对耐阴，较难适应全光照，春秋姜黄和白姜花等姜花属植物相对喜阳，且姜花属植物在过度遮光条件下容易倒伏。参试的9 种姜科植物均适宜在遮光度为70% 左右的环境中种植。

Abstract: Nine Zingiberaceae plants，such as Hedychium coronarium Koen，Hedychium sp.，Hedychium qingchengense Z. Y. Zhu，Alpinia‘ Red harvest’，Alpinia pumila Hook. F.，Curcuma attenuate，Curcuma kwangsiensis S. G. Lee et C. F. Liang，Kaempferia pulchra，Costus bakeri，were used as experimental materials. The physiological properties and morphology of these nine plants were studied under different light intensity. The light response curves including light saturation point（ LSP） and light compensation point（ LCP） data were also measured. According to the light response data of the nine Zingiberaceae plants，combined with actual conservation observation experience，finally，we obtained the approximate range of illumination for each plant. The aim is to provide reference and reference for the refinement and landscape configuration. The results showed that Alpinia pumila Hook. F. and other Alpinia species were relative shade-requiring，of which were difficult to adapt to the whole light. Curcuma attenuate and Hedychium coronarium Koen were relative heliophilous. Under the condition of excessive shading， the Hedychium species would easily cause lodging. It was suitable for planting nine Zingiberaceae plants in the 70% shading environment.
