【摘要】 厚叶岩白菜属虎耳草科岩白菜属草本植物,具有很高的观赏价值。为了探明厚叶岩白菜的物候规律,于2013年采用物候观测法对平原上人工栽培条件下(新疆乌鲁木齐、奎屯市、阿勒泰市林科所)和山区自然生长状态下(喀纳斯湖畔)的厚叶岩白菜进行物候观测。结果显示,人工栽培的返青期、展叶期、花期和果实成熟期比自然状态下的略早,叶色变红比自然状态下的略晚,影响物候期的主要环境因子是年均温、≥10℃的积温和日照时数。该结果可以为厚叶岩白菜的人工栽培提供科学依据和技术支撑。更多还原

【Abstract】 Bergenia crassifolia(L.) Fritsch is a herbs with high ornamental value.Phenological observations about Bergenia crassifolia(L.) Fritsch grown in the plains(Urumqi,Kuytun and Forestry Research Institue of Alaty Prefecture) and the mountains(Kanas lake) were made in 2013 in order to find out its phenological regularity.The results showed that turning green period,leaf expansion stage,flowering and fruit mature period under artificial cultivation are slight earlier than that.And the time when leaves turn red under artificial cultivation is later slightly than that under the natural state.The main environmental factors affecting the phenological period are the annual average temperature,the accumulated temperature over 10℃ and the sunshine hours.The results can provide a scientific basis and technical support for Bergenia crassifolia(L.) Fritsch cultivation.更多还原
