摘　　要： 据物候观测，桐花树隐胎生胚轴最佳采摘在海南（琼山）为８月中旬，廉江为８月下旬，深圳为９月上旬。催芽点播育苗比直接点播育苗成苗率可提高８０．８％，容器袋填充基质以基质Ⅰ为最佳。移栽大小灌丛，成活率均可达１００％。由于受风浪冲击的影响，选择规划造林地时，首先应确定当地的宜林滩涂高程，深圳湾宜林滩涂高程应高于潮高基准面的１．４２ｍ，且土质较为硬实。造林初植密度以０．５ｍ×１ｍ或１ｍ×１ｍ适当密植为宜。桐花树具有极强的忍耐海水淹浸能力，可持续淹浸多年而不死。 The paper deals with propagule collection,seedling nursery and afforestation technique of Aegiceras corniculatum .The best season for propagule collection in Hainan,Liangjiang and Shenzhen is in the middle ten days, the last ten days of August and the first ten days of September respectively. The survival rate of seedlings is the spot sowing of promoting sprout was 80.0% higher than that in the directing spot sowing. Substrate I was the best one among substrates in the container. The survival rate can reach to 100% for transplanting with small and big shrubs. The mudflat height suitable for growing trees must be first selected carefully,because the growth of seedlings and young trees is greatly affected by the tide.The mudflat height suitable to planting is above 1.42 m of the tide datum plane,and the soil must be relatively hard. The space of initial plantation should be 0.5 m×1.0 m or 1.0 m×1.0 m. A.corniculatum have a high tolerance of tide inundation and can normally grow under the staying inundation of sea water for several years.
