摘　　要：从土壤条件、土壤含盐量、沙地自然条件和植物体细胞染色体四方面研究了塔落岩黄芪和细枝岩黄芪种子及幼苗的生物学特性，分析了在自然条件下影响种子发芽及幼苗生长的有关因素，不同年限植物营养体与根系的生长动态，以及塔落岩黄芪和细枝岩黄芪体细胞染色体核型特征。The paper studies biological character of seeds and seedling of Hedysarum laeve and H. scoparium from four fields which is soil condition,saIt content of soil,natural condition of the sand and chromosome of physical cells. It analysed the factors of influence the germination of seeds and growth of seedling in natural condition,the growth trend of phytomata and roots in the different ages of plant and character of chromosome karyot-pes of Hedysarum laeve and H.scoparium.
