摘　　要：该文通过扫描电子显微镜试验研究了松萝凤梨叶片的微观特性。结果表明,松萝凤梨叶表面葵花状鳞片由碟状细胞、环状细胞、翼状细胞组成,并透过柄状细胞和表皮细胞直接与叶片内部的叶肉细胞相连。利用无根无土的松萝凤梨编织成密集度可随心操控的松萝凤梨植物窗帘,该窗帘既具有植物遮阳的优势,又易于进行人为控制,是理想的太阳辐射自控器。研究还表明,松萝凤梨叶片和叶表面鳞片可增加松萝凤梨植物窗帘的辐射表面积,建立了松萝凤梨植物窗帘辐射表面积估算模型。The scanning electron microscope(SEM)experiments are carried out to study the microstructure of the tillandsia usneoides(TU) leaves.The results show that,the sunflower shaped lodicules covering the TU leaves consist of disc cells,ring cells,and wing cells.The lodicules link to the mesophyll cells inside the leaves through the stalk cells and the epidermal cells.The rootless and soilless TU can be intwined linear to form the TU plant curtain with full lengths and densities.The TU plant curtain has the advantages of the general plant shading,and can be easily operated as the ordinary sunshades.The radiation surface of TU plant curtain increases with the TU leaves and the lodicules.An estimated model of the radiation surface of TU plant curtain is built.
