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。
Through experimental study, we know that there are significant differences in the results of using different methods to germinate Astragalus membranaceus seeds. Compared with the conventional method, the germination rate of seeds increased by about 30% compared with the conventional method, and the germination rate of the soil culture method was about 10% higher than that of the variable temperature stimulus method. Compared with the paper bed, the sand bed could reduce or eliminate the phenomenon of mildew , Thereby increasing the seed germination rate.
