不同仙茅属植物在广州的物候期及植物学特征观察

摘要

To study the phenophase and growth characteristics of seven kinds of Curculigo ,under the same conditions of cultivation and manage-ment ,in Guangzhou area ,we observed and recorded their seedling stage ,the first flower flowering stage ,single flowers and group take duration , fructification stage ,leaf dry stage and root enlargement stage ,development characteristics ,growth status .These results showed that there wer some differences in the phenophase between seven kinds of Curculigo in Guangzhou .The seedling frequently occurred in early February ,the length and width of stem and leaf were different ;flowering often happened in April and M ay ,the color of all of them was yellow ,the flower pat-ternwas same basically .This study provides theoretical basis for making reasonable cultivation schemes in Guangzhou city .%为了掌握七种仙茅在广州地区的物候期和生长特性，在相同的栽培管理条件下，观察记录了7种仙茅出苗期、第1朵花的开花期、单花和群花的持续时间、结籽期、叶枯期、根部膨大期的发育特点和生长特性。结果表明，7种仙茅在广州地区的物候期存在一定的差异，其出苗期主要集中在2月初，茎、叶长度及宽度均有差异；花期主要集中在4月份、5月份，花色均为黄色，花型基本一致。该研究可为制定仙茅在广州地区合理的栽培技术方案等提供理论依据。
