不同遮阴度对鼠尾草生长的影响

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。

Effects of Different Shading Levels on the Growth of Salvia farinacea

The effects of different shading levels(0%,50%,70%,90%) on the growth of Salvia farinacea were investigated.The results showed that increasing the degree of shade,Salvia farinacea budding,flowering date postponed and the duration of flowering shortened.In the flowering period,with the degree of shading increased,the plant height,inflorescence length,pedicel length reduced,leaf length,leaf width increased,and the whole plant,aerial parts of plants and root fresh weight and dry weight reduction.It is no signi...
