研究了不同遮阴水平(0%、50%、70%、90%)对鼠尾草生长的影响。结果表明:遮阴程度的加重,鼠尾草现蕾、开花的日期延后,开花持续的时间缩短。在开花期,随着遮阴度的增加,植株高度、花序长度、花梗长度降低,叶片长度、叶片宽增加,而整个植株、植株的地上部分及根系的鲜质量和干质量减少。遮阴处理的叶片数与对照处理的没有显著差异。不遮阴有利于鼠尾草的生长和花期的延长。 The effects of different shading levels (0%, 50%, 70%, 90%) on the growth of sage were studied. The results showed that: the increase of shading degree, the sage budding, the date of flowering delay, flowering duration shortened. At the flowering stage, plant height, inflorescence length and pedicel length decreased, leaf length and leaf width increased with the increase of shading degree. However, the fresh and dry mass of the whole plant, the aerial part of the plant and the root system decreased. There was no significant difference in the number of shaded leaves compared to the control treatment. Shading is not conducive to the growth of sage and flowering extension.
