| 摘要: |
| 通过有序样品聚类分析单叶省藤生长规律,将苗木生长分为5个阶段:出苗期4月4日～5月21日,生长速生期5月22日～6月22日,二次速生期6月23日～7月22日,生长后期7月23日～11月22日,生长停止期11月23日～2月22日。其生长阶段缺少生长初期,而是直接进入速生期,并且有一个二次速生期。除了在两个速生期加强水肥管理外,在生长后期适当管理也能增加其生长量。 |

| Abstract: |
| Ordered specimen cluster analysis was used to characterize the early growth process of Calamus simplicifolius seedlings. The process could be divided into five stages:juvenile stage(April 4-May 21),rapid growth stage(May 22-June 22),second rapid growth stage(June 23-July 22),late growth stage(July 23- November 22)and stopping growth stage(November 23-February 22). Seedlings went straightly into two continual fast growth stages,without an obvious early growth stage. Accelerated growth could be gained with strengthened fertilization and irrigation in the two fast growth stages as well as appropriate management in late growth stage. |
