摘　　要：通过试验研究得知，塔落岩黄芪种子采用不同的方法进行发芽其结果有着明显的不同。变温刺激可以使种子发芽率比常规法高出３０％左右，而土培法又比变温刺激法发芽率高出１０％左右；沙床与纸床相比，沙床可减轻甚至消除种子霉烂现象，从而提高种子的发芽率。The seed germination of (Hedysarum laeve) was studied in this paper. The results showed that germination percentage had distinct difference by different methods: poikilothermal stimulation was 30% higher than usual method; soil culture was 10% higher than poikilothermal stimulation. Compared with paper bed, sand bed could increase germination percentage by reducing seed mildew and roting.
