摘　　要：通过对葎草开花过程的观察,借助温度计、阿斯曼通风干湿表等仪器,对葎草有性繁殖花序开始及持续时间及其开花与温度、湿度的关系进行了观测与测定,结果表明:葎草花序为有限花序,南充地区葎草10月中旬始花,到11月下旬结束,花期长达1月余;一天中开花是在4∶00～12∶00之间,花蕾开放85%以上在6∶00～12∶00之间;葎草开花的最适温度为16℃～18℃,要求的空气相对湿度为60%～70%。affect Humulus last, then some By determinating the Humulus Scandens flowering and measure results of how temperature and humidity Scandens＇ s sexual reproductive inflorescence, such as： when does the blossom begin and how long it figures come to our eyes. In the process of experiment, the thermometer and A Siman Ventilates Psychrometer are applied to get accurate figures. The results show that the inflorescence of Humulus Scandens is definite and in Nan Chong it always begins in mid-october and ends in last november. The flowering season lasts more than a month; in a day the flowering time is between 4：00 to 12：00, and more than 84% buds open between 6：00 to 12：00; the most favorable temperature of bud opening is 16℃- 18℃ and the most suitable humidity is 60% - 70%.
