从植物更新生态位的角度，结合野外实地考察，用室内试验的方法研究了西北地区骆驼蓬属种子萌发的条件，分析了降水量、种子埋藏深度等因子对其累积发芽率的影响，并对该属植物在长期进化过程中，为适应干旱生境所形成的生态对策进行了探讨
From the point of view of plant regeneration niche, combined with the field investigation, the indoor germination conditions of Pear species in Northwest China were studied by means of laboratory experiments. The effects of precipitation and seed burial depth on the cumulative germination rate were analyzed. The genus in the process of long-term evolution, in order to adapt to the formation of ecological habitat drought habitat were discussed
