目的:在山茱萸花期内,通过观察温、湿度的变化探索生态因子对其开花习性及开花的影响。方法:在山茱萸花期内连续5昼夜每隔2h测量温度和湿度,同时记录其开花数。结果:山茱萸在1天中开花时间为6∶00-16∶00,花蕾开放85%以上在8∶00-14∶00;开花的最适温度为10℃～14℃,湿度为45%～55%。结论:适宜的温湿度是山茱萸开花的必要条件,生态因子与山茱萸开花有着密切的关系。
OBJECTIVE: To explore the effects of ecological factors on flowering habits and flowering during the flowering period of Dogwood by observing the changes of temperature and humidity. Methods: The temperature and humidity were measured every 2 hours in the flowering period of Fructus Corni, and the number of flowering was recorded. Results: The flowering time of dogwood was 6: 00-16: 00 in 1 day, the flower buds were more than 85% in 8: 00-14: 00; the optimal temperature for flowering was 10-14 ° C and the humidity was 45-55 %. Conclusion: Appropriate temperature and humidity are the necessary conditions for the flowering of dogwood. The ecological factors are closely related to the flowering of dogwood.
