摘　　要：以翡翠柚和处红柚为试材,研究洋丰复合肥(N∶P_2O_5∶K_2O=15∶15∶15,总养分≥45%)、撒可富复合肥(N∶P_2O_5∶K_2O=16∶6∶18,总养分≥40%)、黄腐酸钾豆粕有机肥和羊粪4种肥料不同配方施肥对2种柚子的生长及土壤性状的影响。结果表明:撒可富复合肥(N∶P_2O_5∶K_2O=16∶6∶18,总养分≥40%)+黄腐酸钾豆粕有机肥配方施肥对2种柚子的效果最好,其中,可溶性固形物、总糖、还原糖和维生素C含量和可食率最高,总酸含量最低,果实产量最高;土壤性状方面,有机质含量最高,p H值酸性降低,土壤容重最低。Using Citrus grandis‘Feicui’and Citrus grandis‘Chuhong’as experimental materials,4kinds of different fertilizer on the varieties of grapefruit’s growth and soil properties were studied,including Yangfeng compound fertilizer(N,P2O5,K2O=15,15,15,total nutrient≥45%),and Sakefu compound fertilizer(N,P2O5,K2O=16∶6∶18,total nutrient≥40%),fulvic acid potassium soybean meal organic fertilizer and dung.The results showed that prescription fertilization of Sakefu compound fertilizer and the fulvic acid potassium soybean meal organic fertilizer got the best effect for the two varieties of pomelo.The soluble solid,total sugar,reducing sugar and vitamin C content and edible rate were the highest,the total acid content was the lowest,and the fruit yield was the highest.The fertilization changed the soil character,which got the highest organic matter content,lower pH value,and the lowest soil bulk density.
