摘　　要：为了发展油茶产业,近年来桂林市在有关县建立了多个油茶丰产示范林基地。2012年7月笔者对部分示范林进行调查,结果表明,灵川、兴安、龙胜①3个示范点生长最佳,其中灵川点的平均树高高于阳朔点的29.49%、灌阳点的13.48%、龙胜②点的14.77%;从平均开花株率看,灵川点为68.92%、龙胜①点为63.02%,显著高于灌阳、龙胜②、阳朔3个点相应的平均值。通过调查分析认为,油茶的生长势、开花挂果与造林品种选择、林地抚育、施肥有显著差异,采用良种嫁接苗和每年抚育、施肥2次的油茶植株生长良好,开花挂果率高,反之则差。最后指出在发展油茶产业中必须加强良种繁育与推广、示范基地建设、科技体系建设和改善种植方式等。In order to develop Camellia oleifera industry in recent years, Guilin has established some high-yielding Camellia oleifera demonstra- tion forest base in the county. The field survey was conducted in July 2012. It was concluded that Camellia oleifera grow best in three demonstra- tion sites, including Lingchuan, Xing＇an and Longsheng County. The average tree height of growth in Lingchuan is higher than 29.49% of Yang- shuo, 13.48% of Guanyang, and 14.77% of Longsheng; The average flowering plants rate in Lingchuan is 68.92% , and in Longsheng is 63.02%, significantly higher than the corresponding average three points of Guanyang, Longsheng, Yangshuo. Survey analysts believe that the growth potential and flowering of Camellia oleifera has significantly different in species selection, and woodland tending fertilization. Camellia ole- ifera plant growth well, flowering and fruiting high when afforestation using grafted seedlings of improved varieties, and has twice tending and fer- tilization one year, otherwise poor. It is necessary to strengthen the breeding and promotion, demonstration base construction, science and tech- nology system construction and improvement of cultivation methods, et al.
