摘　　要：油茶专用肥是针对油茶的生长发育规律而专门设计的一种生物有机肥。通过一系列施肥试验,探讨其与茶农普遍施用的复合肥及有机颗粒肥的肥效区别。结果表明:不同施肥处理均能显著提高土壤中有机质、全氮、全磷和速效钾的含量;只有油茶专用肥能显著提高土壤中速效磷的含量;除复合肥A1处理外,其它各施肥处理均可显著提高土壤中速效氮的含量;油茶专用肥能同时显著提高土壤中细菌、真菌及放线菌的数量,其作用效果要优于复合肥和有机颗粒肥。主成分分析结果表明,油茶专用肥C1处理的综合得分最高,即其对油茶幼林土壤状况的改良效果最好。Camellia oleifera special fertilizer is a kind of bio-organic fertilizer,which was specially designed according to the growth and development regularity of Camellia oleifera.By a series of fertilization experiments,the fertilizer efficiency differences among Camellia oleifera special fertilizer and compound fertilizer and organic granular fertilizer which were generally applicated by Camellia oleifera growers were investigated.The results show that different fertilizer treatments all can significantly increase the content of soil organic matter,total N,total P and available K;only Camellia oleifera special fertilizer can significantly increase the soil content of soil available P;all the fertilizer treatments（except A1 treatment of compound fertilizer） can significantly increase the content of soil available N;Camellia oleifera special fertilizer can simultaneously significantly increase the number of soil bacteria,fungi and actinomycetes,its function effect was better than compound fertilizer＇s and organic granular fertilizer＇s.The result of principal component analysis show that the C1 treatment of Camellia oleifera special fertilizer had the highest comprehensive scores,this means that the C1 treatment of Camellia oleifera special fertilizer had the best improvement effect on the soil conditions of Camellia oleifera young forest.
