查询词典 acorus calamus

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

The constructed wetland process was applied to treat rural domestic sewage. The results showed that the abilities of different macrophyte species to remove nitrogen and phosphorous were quite different with each other. Acorus calamus Linn has stronger ability to remove TP and NH3-N.

采用潜流式人工湿地工艺处理农村生活污水，结果表明：不同植物对氨氮、总磷的去除能力差别较大，菖蒲对总磷和氨氮净化效果较好。

Based on the laboratory building the small aquatic ecosystem, removal efficiency of total nitrogen and total phosphorus by Acorus Calamus, Tonina Fluviatilis and Hygrophila difformis with submerged and emerged cultivation was researched. The results showed that the content of TN was 68.43-279.31 and 23.44-170.13mg in shoots and in roots, respectively.

通过在室内构建小型水生生态系统，研究了挺水和沉水培养模式下大水剑、太阳草、水萝兰3种水生植物体内氮磷含量及去除生活污水中氮磷的能力。

The content of TP was, 9.11-42.79mg and 10.81-28.71 mg in shoots and in roots, respectively. The highest content of TN and TP was in Hygrophila difformis and then Tonina F1uviatilis, the lowest in Acorus calamus.

结果表明，3种水生植物地上部和地下部氮累积量分别在68.43-279.31mg和23.44~170.13mg之间；地上部和地下部磷累积量分别在9.11~42.79mg和10.81~28.71mg之间。

The main resultsshowed that the average removal efficiency on Total Nitrogen with planted Phragmites communis and Canna indica were higher than 90% for 1 day and 3 days, but the removal efficiency with planted Scirpus validus and Acorus calamus changed from 51.90% for 1 day to 90.90% for 3 days; The removal efficiency was not significantly different from each other on Total Phosphorus except for Phragmites communis; The combination of Phragmites communis and Canna indica, Typha orientalis and Acorus calamus were good at removing COD; the removal efficiency on NH_4~+-N was the highest with planted Acorus calamus.

结果显示，芦苇和美人蕉组合对总氮的去除率在停留1天和3天时均达到90％以上，而水葱—菖蒲组合变幅较大，从停留1天的51.90％增加到停留3天的90.90％；植物对TP的去除率除了芦苇组合偏低以外，其它植物差别不明显；芦苇—美人蕉组合和香蒲—菖蒲组合对COD去除较好；菖蒲组合对NH_4~+-N去除效果最好。
