摘　　要：采用栽培、观察的方法比较了沼生蔊菜(风花菜)与荠菜形态及生物学特征,同时比较了根和叶的营养成分。结果表明,作为极为相似的两种山野菜,在形态及生物学特征和营养成分方面差别是显著的,在形态学方面表现在出土子叶、二真叶期、四真叶期、基生叶、茎生叶、种子、果实、花等方面的不同。在生物学特征方面,两种植物在物候及生活史方面显著不同。在营养成分方面,沼生蔊菜除叶片可以食用外,其肥大直根也可以食用,而且营养价值很高,两植物叶片的营养价值有差异。The morphological and biological characteristiCS of Rorippa islandica（Oed. ）Borb. and Capsella bursa-paestoris（L. ）Medic. as well as the nutrient content of their roots and leaves were compared by cultivating and observation. The result indicates that there are distinct differences in the morphological and biological characteristics and nutrient content of these two Similar wild plants. Morphologically, the differences appear in the cotyledon coming out of land, the second euphytta period, the fourth euphytta period, radical leaves, stem leaves, seeds, flowers and seeds etc. ：Biologically, the biotemperature and life history of the two plants are different obviously： As for the nutrient content, the fleshy tap root of the Rorippe islandlca is edible besides its leaf, which has Very high nutritive value. Meanwhile, the nutritive value of the leaves iS different in the two plants.
