摘要 对8种阴生地被植物在不同遮荫栽培处理条件下,进行了生长状态、光照强度、温湿度、光合作用特性、叶绿素含量、显微结构和理化指标几个方面的测定分析和指标评价研究。结果表明:玉簪、金边玉簪、紫萼和荚果蕨最适宜在半阴条件下(光通量90~360μmo.lm-2s-1或5 000~20 000Lux、遮光率20%~45%)生长,是典型的阴生地被植物;紫花地丁、连钱草、蛇莓和常春藤在强阳(大于光通量900μmo.lm-2s-1或5万Lux)和浓荫条件下(小于光通量90μmo.lm-2s-1或5 000Lux、遮光率小于15%)均生长旺盛,是既喜阳又耐阴的地被植物。 In this study, the growth state, light intensity, temperature and humidity, photosynthetic characteristics, chlorophyll content, microscopic structure and physiological indicators of eight shade ground cover plants under different shade planting conditions are measured, analyzed and evaluated. The results show that: Hosta plantaginea, H. "Yellow splash Rim', H. ventricosa, Matteuccia struthiopteris are most accustomed to grow in the half shade condition (luminous flux 90-360mol.m^-2s^-1, or 5 000 - 20 000Lux, shading rate of 20%-45%) and are typical shade ground cover plants; Viola yedoensJs, Glechoma longituba, Duchesnea indica, Hedera helix grow luxuriantly in strong sunlight lgreater than the luminous flux 900 mol.m^-2s ^-1, or 50 000Lux) and deep shade lluminous flux less than 90mol.m^-2s^-1 or 5 000Lux) conditions and are ground cover plants tolerant to both sunlight and shade.
