摘　　要：为给油茶林地施肥管理提供科学依据,对广东省油茶林地土壤养分进行测定分析。结果表明:不同试验区域及同一试验区域不同试验点土壤养分含量存在巨大差异,在油茶养分管理时就必须根据实际情况分别采用不同的施肥措施;表土层的碱解氮、速效磷、速效钾、Ca2+和Mg2+含量均明显高于底土层含量,在施肥时应当注意施肥深度,以利于根系对养分的吸收。In order to provide scientific basis for management of fertilization in Camellia oleifera forest land, we determined and analyzed soil nutrient of C.oleifera forest land in Guangdong. The results showed that： soil nutrient content in different experimental area and different experimental points in the same test area had a great difference, so we must be adopted different fertilization measures according to the actual situation when Camellia nutrient management; epipedon available nitrogen, available phosphorus, available potassium, Ca2＋ and Mg2＋ content was significantly higher than the content of subsoil, we should be paid attention to in fertilization depth in order to facilitate the root absorption of nutrients
