| 摘 要： | 不同光质和肥料浓度对小报春(Primula forbesii)幼苗生长的影响进行了研究。结果表明:蓝光能促进小报春幼苗的光合速率和蒸腾速率,黄光能明显地促进小报春幼苗增高,红光则促进植株开花;肥料浓度EC 2.0 mS cm-1对促进小报春幼苗生长及叶面积增大的效果最佳;交互处理试验以红光/EC 2.0 mS cm-1的效果最明显,对小报春幼苗的营养生长和生殖生长均有促进作用。因此,选择合适的光质和肥料浓度有利于促进植物的生长发育。

| Abstract: | The effects light quality and fertilizer concentration on seedling growth of Primula forbesii were studied. The results showed that blue light could enhance photosynthetic rate and transpiration rate of seedlings, yellow light significantly increase seedling height, and red light promote flowering. There were the best effects of seedling growth and increased leaf area with fertilizer concentration of EC 2.0 mS cm-1. When treated with red light and EC 2.0 mS cm-1 fertilizer, the vegetative and reproductive growth of seedlings enhanced. It suggested that suitable light quality and fertilizer could promote plant growth. |
