93.71%。嫁接栽培及增施肥料还可显著增强土壤氮、磷、钾供应能力。关键调：番茄；嫁接栽培；施肥；产量；养分利用效率

Abstract: In order to investigate the effects of grafting cultivation on tomato yield, characteristics of nutrients up take and utilization, the relationship between cultivation methods and fertilization to tomato yield, NPK uptake and use efficiency was studied using split plot design. The results showed that compared to self-rooted tomato, the yield of grafted tomato was increased by 30. 76% , the absorption of N, P,O, and K,0 increased by 27. 88% , 28. 21%%%e Meanwhile, combined application of N, P and K could increase the yield, absorption and utilization rate of N, P and K compared to single element fertilizer application, the yield of tomato under the treatment of NPK wa8 42. 52% , 68. 62% and 50. 10% higher compared to that under single application of N, P and K, consequently the utilization efficiency of N, P and K increased by 103.16%,181.58% and 93.71%,respectively.In addition，
grafting and adding fertilization could enhance the soil N, P and K supply capacity significantly Key words: tomato; grafted cultivation; fertilization; yield; utilization efficiency of nutrients
