摘　　要：通过 2年野外观察和栽培实验 ,对光萼茅膏菜的生活史特征、种群动态以及食虫习性进行了初步研究。结果表明 :光萼茅膏菜为早春植物 ;该种以球茎行营养繁殖 ,虽然种子产量较大 ,但实生苗更新能力较低 ;花期植物捕虫率最高 ;Life history traits,population dynamics and insectivorous habits of Drosera peltata var.glabrata were primarily studied in both natural and cultivated population.The results were as fol- lows:1 this species is early spring plant according to its phenology;2 vegetative reproduction by corn is main reproductive way,the surviving rate of seedling is low;3 plants had the highest rate of insecti- vores in blossoming period;4 the biomass and seed production of insectivorous plants was higher than those of non- insectivorous plants.
