| 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：光萼茅膏菜杰早春植物；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；食虫对植物生长和繁殖有一定益处。

| Abstract: | 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. |
