摘要： 为研究氮磷钾不同比例配施对温室番茄产量和品质的影响，试验设5个施肥配比处理，不施肥、氮磷钾配比1：0.7：1，0.7：0.7：1，1：0.49：1，1：0.7：0.7，测定不同处理对番茄产量、品质及对养分的吸收情况，为日光温室番茄氮磷钾合理施肥提供理论依据。结果表明，与CK相比，氮磷钾配施整体上可使番茄产量提高4.1%~9.9%，其中氮磷钾配比为1：0.7：0.7时产量为92.92 t/hm²，显著高于其他处理（P <0.05）；处理4中番茄果实Vc、可溶性糖和可溶性固形物含量较CK分别提高了62.5%，16.8%，6.1%；与CK相比，处理4中氮素含量为28.71 mg/g，较其他处理高出14.24%~20.38%，处理2中磷和钾含量较高，分别为3.85，27.00 mg/g，与其他处理差异性显著（P <0.05）；综合考虑产量、品质等，在本试验条件下，氮磷钾配比1：0.7：0.7时为最适配比。

Abstract: In order to investigate the effects of NPK fertilization on the yield and quality of tomato,provide theoretical basis for reasonable fertilization of N,P and K in tomato. There were five fertilization ratio treatment,no fertilizer,NPK ratio was 1:0.7:1,0.7:0.7:1,1:0.49:1 and 1:0.7:0.7,to determine the different treatments on tomato yield,quality and absorption of nutrients. The results showed that,compared with CK,N,P and K fertilization ratio treatment could increase tomato yield by 4.1%-9.9%,When the ratio of N,P and K was 1:0.7:0.7,the yield was 92.92 t/hm²,significantly higher than other treatments(P <0.05); The content of Vc,soluble sugar and soluble solids of tomato fruit in treatment 4 increased by 62.5%,16.8%,6.1%; Compared with CK,the nitrogen content in Treatment 4 was 28.71 mg/g.,14.24%-20.38% higher than other treatments,treatment 2 had higher phosphorus and potassium content,was 3.85,27.00 mg/g,significantly different from other treatments(P <0.05); Considering the yield,quality and so on,under the experimental conditions,the optimum ratio of N,P,K was 1:0.7:0.7.
