| 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. |
