优良园林绿化树种阿丁枫育苗技术研究

Study on the Sowing Seedling-raising of Altingia chinensis

通过对阿丁枫的种子采集处理、种子主要参数测定、育苗方法试验和对苗木生长观测调查,初步研究了阿丁枫的育苗技术、苗期生长规律。结果表明:阿丁枫大田育苗播种量以4～5 g/m2为宜,1 a生苗高平均可达45 cm,地径平均0.8 cm,根系发达,可出圃造林;苗高生长高峰在8～9月上旬,期间应加强水肥管理,促进苗木生长。

Seeds＇ collecting, treating of the seeds＇ main parameters, technic of seedling-raising and growth observation of Altingia chinensis were researched in detail. The growth rules and seedling-raising technic of this specie were also discussed. The result indicated that 4-5 g/m^2 was the better quantity for the field sowing. The average height of the annual seedling of Altingia chinensis was 45 cm, the average ground diameter was 0. 8 cm, and the root system was strong. All these suggested that it can be better for afforestation. Altingia chinensis grew fastest during August and September, and appropriate irrigation was needed for promoting it＇s growth during this time.
