【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。更多还原

【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.更多还原
