摘　　要：油茶是我国南方重要的经济树种之一,为探究不同施肥方式对油茶生长情况,以油茶容器苗为研究对象,通过交叉实验分析了不同氮、磷、钾配比和施肥量对油茶株高和地径增长量的影响,结果表明:氮、磷、钾配比和施肥量对油茶的株高及地径增长量均有显著影响,在3种不同的施肥量中,氮、磷、钾配比2∶1∶1和3∶1∶1的株高增长量最大,氮、磷、钾配比4∶1∶1条件下地径增长量最大;在不同的氮、磷、钾配比中,施肥量0.6 g/株的株高增长量和地径增长量均最高,综合株高和地径情况,在油茶培育的肥料管理中,氮、磷、钾配比建议使用3∶1∶1进行配置,并将施肥量控制在0.6 g/株。Camellia oleifera is one of the important economic tree species in southern China.In order to explore the effects of different fertilization methods on the growth of Camellia oleifera and provide a theoretical basis for fertilizer management in Camellia oleifera seedling cultivation,this study focused on container-grown Camellia oleifera seedlings.A cross-experiment was conducted to analyze the effects of different nitrogen,phosphorus,and potassium ratios and fertilization levels on the height and basal diameter growth of Camellia oleifera seedlings.The results showed that the nitrogen,phosphorus,and potassium ratios and fertilization levels had significant impacts on both the height and basal diameter growth of Camellia oleifera.Among the three different fertilization levels,the 2:1:1 and 3:1:1 nitrogen,phosphorus,and potassium ratios resulted in the greatest increase in seedling height,while the 4:1:1 ratio led to the largest increase in basal diameter.Among the different nitrogen,phosphorus,and potassium ratios,the fertilization level of 0.6 g per seedling resulted in the highest increase in both height and basal diameter.Therefore,for fertilizer management in Camellia oleifera seedling cultivation,it is recommended to use a nitrogen,phosphorus,and potassium ratio of 3:1:1 and control the fertilization level at 0.6 g per seedling.
