1. It was shown that(1) in the community, the photosynthetic active radiation decreased from canopy to herbaceous layer and differed among the arbor, shrub and herbaceous layers(P<0. 05); 结果表明:(1)从林冠层到草本层,光合有效辐射强度明显减弱,并且乔木层、灌木层和草本层之间的差异均达到了显著水平(P<0。05);
2. Bryophyte cover and richness were mainly influenced by herbaceous layer biomass, while bryophyte biomass was significantly affected by herbaceous layer height. 草本层生物量对苔藓盖度和种丰富度起主导作用, 草本层高度是对苔藓生物量有显著影响的主导因子。
3. Consider to make clear, the root of herbaceous peony and root of herbaceous peony contain peony glucoside and have spasmolysis contraction effect. 研究表明,赤芍和白芍都含有芍药甙而有解痉挛作用。
5. Results Besides the similar structure of the perennial herbaceous dicotyledon, there were a lot of fibers and calcium oxalate crystals in the plant. 结果山麻黄除具有双子叶植物的一般组织结构特征外,还具有发达的纤维和大量草酸钙簇晶。
