| 【目的】研究不同光质处理对岩白菜形态指标和生物量的影响，为岩白菜的高效栽培提供参考。【方法】2011-2012年，在人工栽培岩白菜时，通过覆盖蓝色、红色、绿色、黄色和白色塑料薄膜，获得5个不同光质处理，比较各光质处理对岩白菜株高、株幅、叶长、叶宽、根状茎直径、叶片数等形态指标和生物量的影响。【结果】覆盖黄膜有利于岩白菜株高、株幅、叶片数、叶长、叶宽和根状茎直径的增加，覆盖蓝膜最不利于上述形态指标的增加。红膜、白膜和黄膜处理有利于岩白菜单株鲜质量和干质量的增加，而蓝膜处理则表现出抑制作用。【结论】在人工栽培岩白菜时，覆盖黄膜和红膜有利于岩白菜生长和生物量的积累。 |

| Abstract: |
| 【Objective】This paper researched the effects of different light qualities on morphological and biomass characters of Bergenia purpurascens to provide scientific basis for their high effective cultivation.【Method】Five light quality treatments were obtained by covering blue,red,green,yellow and white plastic films over plants during 2011-2012 and the effects of different light qualities on plant height,plant width,leaf length,leaf width,rhizome diameter,leaf number and biomass of B.purpurascens were compared.【Result】Covering yellow film was beneficial to increase plant height,plant width,leaf number,leaf length,leaf width and rhizome diameter while covering blue film was unsuitable for the increase of above characters.Covering red,white and yellow films was in favor of increasing the fresh weight and dry weight while covering blue film would inhibit the increase of fresh weight and dry weight.【Conclusion】Covering yellow and red films was suitable for the growth and accumulation of dry materials in B.purpurascens. |
