摘　　要：采用L9(34)正交试验设计,研究田间不同水肥管理技术3因素(品种、施肥量、灌溉强度)对葡萄柚果实单果重、硬度、果皮厚度、可食率、横径和纵径等外观品质的影响。采用直观分析和方差分析进行综合评价,结果表明,田间不同水肥处理对葡萄柚果实硬度和果实横、纵径变化具有显著影响。其中,品种因素对果形指数的影响最大。施肥因素是影响果实硬度、可食率和果实横、纵径的关键因子,对果实硬度和果实横、纵的影响分别达到显著(P=0.023)和极显著(P=0.002,P=0.003)水平。本试验中,葡萄柚果实外观品质最佳处理为星路比施肥1 kg灌溉2次/株/月。In order to study the effect of different field water and fertilizer managements on grapefruit fruit exterior quality,three factors（ variety,fertilizing amount and irrigation intensity） were employed to study difference of fruit weight,firmness,peel thickness,edible rate,transverse diameter,vertical diameter and fruit shape index by using orthogonal experimental design of three level three factors L9（ 34）. According to visual and variance analyses,the results indicated that the contents had significantly difference in fruit firmness,transverse diameter and vertical diameter with different field water and fertilizer managements. Variety had the greatest influence on fruit shape index. Fertilizing had the greatest contribution to fruit firmness,edible rate,transverse diameter and vertical diameter. It contributed significantly or extremely significantly difference to fruit firmness（ P = 0. 023）,transverse diameter and vertical diameter（ P = 0. 002,P = 0. 003）,respectively. In this study,the optimal treatment had highest fruit exterior quality was‘Star Ruby＇variety with 1 kg compound fertilizer and 2 irrigation per plant per month.
