不同人工补光处理对2个微型月季品种生长的影响

Effects of Different Artificial Light Treatments on the Growth of Two Miniature Chinese Rose Cultivars

以微型月季芳香王阳台(Fragrance king terrazza)和红宝石阳台(ruby terrazza)为试验材料,以高压钠灯为光源,以2、4、6 h的补光时间和2000、4000、6000、8000 lx的光照强度为处理,研究不同补光时间和补光强度对微型月季扦插苗生长的影响。结果表明,在8000 lx光强下补光6 h,2种微型月季达到最大冠幅;在8000 lx光强下补光2 h,芳香王阳台的开花数达到最大值,在8000 lx光强下补光4 h,红宝石阳台的开花数达到最大值,与对照相比均有显著增加;在8000 lx光强下补光4 h,芳香王阳台的株高达到最大值,而红宝石阳台在6000 lx光强下补光6 h时的株高达到最大;同时,人工补光还可促进2种微型月季花径的增加。

Using fragrance king terrazza and ruby terrazza as research materials and high pressure sodium lamp as light source,the effects of different times and intensities of supplementary light on cuttings growth of miniature Chinese rose were studied.The results showed that the maximum crown amplitude of two kinds of Chinese rose reached at the light intensity of 8000 lx for 6 h.The number of flowers in the balcony of fragrant king reached the maximum value after 2 hours of supplementary light under the light intensity of 8000 lx,and the number of flowers in the balcony of ruby reached the maximum value after 4 hours of supplementary light under the light intensity of 8000 lx,which significantly increased compared with the control.Under the light intensity of 8000 lx,the plant height of the balcony of aromatic king reached the maximum value for 4 hours,while the plant height of the balcony of ruby reached the maximum value for 6 hours under the light intensity of 6000 lx.At the same time,artificial supplementary light could also promote the increase of two kinds of miniature Chinese rose flower diameter.
