宛田红花油茶播种育苗试验研究

通过对宛田红花油茶的种子采集处理、种子主要参数测定及育苗方法进行试验和对苗木观测调查，初步研究了宛田红花油茶的育苗技术、苗期生长规律。结果表明：宛田红花油茶大田育苗播种量以420～450g／m^2为宜，1年生苗高平均可达35．2cm，地径平均0．55cm．根系较发达，可出圃造林；苗高、径生长高峰在7月下旬至9月上旬，期间应加强水肥管理，促进苗木生长。

Study on the Sowing Seedling-raising of Camellia polyodonta

Seed＇s collecting, treating of the seed＇s main parameters, technic of seedling-raising and growth observation of Camellia polyodonta were researched in detail. The growth rules and seedling- raising technic of this specie were also discussed. The result indicated that 420-450g/m^2 was the better quantity for the field sowing. The average height of the annual seedling of Camellia polyodonta is 35.2cm,the average ground diameter is 0.55cm. ,and the root system is strong. All these suggested that it can be better for afforestation. Camellia polyodonta grew fastest in the period of late July to early September, and appropriate irrigation was needed for promoting it＇s growth during this time.
