摘　　要：[目的]为沙糖桔的高产、优质栽培提供理论指导。[方法]以3年生沙糖桔果树为供试对象,以传统习惯施肥为对照,研究有机、无机肥料不同配施方案对沙糖桔产量、Vc、总糖、还原糖含量和总酸度的影响。[结果]株施有机肥料6 kg、化肥N 0.3 kg、P2O50.1 kg、K2O 0.55 kg可显著提高沙糖桔的产量;株施有机肥料6 kg、化肥N 0.45 kg、P2O50.2 kg、K2O 0.4 kg可显著提高沙糖桔的产量、极显著提高沙糖桔果实的蔗糖含量和糖酸比;各处理沙糖桔的Vc含量均高于对照。[结论]综合考虑各方面因素,沙糖桔的最佳施肥方案为:株施有机肥料6 kg、无机肥料纯N 0.45 kg、P2O50.2 kg、K2O 0.4 kg。[Objective ] The study was to provide the theoretical guidance for cuhivation of citrus shatangju with high yield and quality. [ Method] With 3 years old citrus shatangju fruit trees as the materials and traditional custom fertilization as CK, the effects of different fertilizing schemes with organic and inorganic fertilizer on yield, contents of Vc, total sugar and reducing sugar and total acidity of citrus shatangju were studied. [ Result ] It could significantly increase the yield of citrus shatangju when 6 kg organic fertilizer, 0.3 kg pure N, 0.1 kg P2O5 and 0. 55 kg K2O were applied for each plant. It could significantly increase the yield of citrus shatangju and very significantly increase its sucrose content and sugar-acid ratio when 6 kg organic fertilizer, 0.45 kg pure N, 0.2 kg P2O5 and 0.4 kg K2O were applied for each plant. The Vc content of citrus shatangju in all treatments were all higher than that of CK. [ Conclusion] Comprehensively considering the factors in many aspects, the optimum fertilizing scheme for citrus shatangju was applying 6 kg organic fertilizer, 0.45 kg pure N, 0.2 kg P2O5 and 0.4 kg K2O for each plant.
