摘　　要：为筛选出容县沙田柚种植最适宜的冬肥配方,对容县不同树龄沙田柚进行不同配方冬肥施肥试验。结果表明,处理3(鸡粪22.0 kg/株,硫酸钾0.50 kg/株,硅钙镁肥2.50 kg/株)在初结果树果园、壮年树果园、老树果园的施用综合表现均优于对照和其他处理,但最适宜初结果树,能使其产量合理,品质最佳,平均单株产量40.87 kg,可溶性固形物达13.53%,固酸比达32.881 7;且与果园常规管理对照相比,氮施用量减少42.40%,磷施用量减少64.00%,钾施用量减少52.00%,实现了化肥减量增效。In order to select the most suitable winter fertilizer formula for planting Shatian pomelo in Rong county, different winter fertilizer fertilization experiments were carried out on Shatian pomelo with different tree ages.The results showed that the comprehensive performance of the third treatment, Chicken Manure 22.2, Potassium sulfate 0.50, Potash-Calcium-Magnesium Fertilizers 2.50 kg·plant-1, was better than that of the control and other treatments in the initial fruit tree orchard, the adult tree orchard and the old tree orchard, but the most suitable for the initial fruit tree could make its yield reasonable and quality best. The average yield per plant was 40.87 kg, the soluble solid content was 13.53%, and the solid acid ratio was 32.8817. Compared with the conventional management of orchard, the application amount of nitrogen, phosphorus and potassium decreased by 42.40%, 64.00% and 52.00%, respectively.The efficiency of fertilizer reduction had been realized.
