摘要
探究水田七的耐阴特性,明确其最适合的遮阴强度,以期为林下提供适应的耐阴药材。在不同的遮阴处理下对水田七的农艺性状、叶绿素含量及光合特性进行测定。结果表明,遮阴率为75.0%时,水田七的株高、叶柄长及总叶绿素含量最高;茎粗为最小。四种遮阴处理下水田七在遮阴率为75.0%的光合-光响应强度整体上高于遮阴率为50.0%和遮阴率为25.0%的处理,并显著高于遮阴率为0.0%处理,说明水田七具有一定的耐阴性,在高遮阴环境下具有较强的适应能力。
We aim at to research that different shading treatment have different impacts on Schizocapsa plantaginea in order to know the suitable for growing in highly shady rate environment of Schizocapsa plantaginea Hance.Test results were as follows： When shading rate was 50%, The test results show that effects of the plant hight petiole length and immortality was the highest. While and the steam crude rate is lowest. Generally, net photosynthetic rate of these medicinal plants in the environment of shading rate of 75% was higher than that of shading rate was 50% and the shading rate of 25%, and was significantly higher than that in the environment of shading rate of 0% for the control group. It can be proved that the Schizocapsa plantaginea Hance is more suitable for growing in highly shady rate environment.
