摘　　要：通过对马蔺花和太阳花的种间竞争实验的研究,观察两种花的生长状况及趋势,研究两种花在环境因子变化下的生长可塑性.结果表明,分别控制光照、氮素、水分,种子发芽的温度范围为15~30℃,两种花种间竞争中太阳花获胜;而太阳花生长受光影响小;随施加N素量的增加,其株高和叶数均呈降低的趋势.This experiment through Malan Flower and sunflower interspecific competition of experimental research,to observe the growth status of two flowers and trend,it is concluded that the two flower growth plasticity under environmental factors change. The results show that each control light,nitrogen,water,seed germination temperature in the range of 15 to 30 ℃. Marin spent with sunflower interspecific competition ended in failure; And sunflower in a light case better than light cases growth; With the increase of applying amount of N experiment,the plant height and leaf number were a trend of decrease.
