摘　　要：通过对荞麦叶大百合(Cardiocrinum cathayanum)的仿生栽培与观测,研究鳞茎大小与基生叶生长的关系。结果表明,荞麦叶大百合基生叶的生长变化遵从"S"形曲线,生长最快的时期是3月17日至3月23日,基生叶面积与鳞茎平均直径遵循y=60.856x-48.711的极显著线性关系。Through the bionic cultivation, observations and measurements of Cardiocrinum cathayanum, we studied the relation ship between bulb sizes and basal leaves＇ growth rhythm. The basal leave growth rhythm of Cardiocrinum cathayanum obeies ＂S＂ curve. The fastest growing period is from March 17th to March 23 rd. The basal leaf area and the average diameter of bulbs follows highly significant linear relationship of y= 60. 856x-48.711.
