摘　　要：通过田间试验,对比分析不同氮肥追施再生水灌溉处理下番茄产量、氮肥偏生产力、番茄携出氮、番茄果实维生素c、有机酸、蛋白质、可溶性糖及糖酸比,研究减量追氮对再生水灌溉设施番茄产量和品质的影响。结果表明,与清水灌溉相比,适量减施追肥再生水灌溉处理显著增加了番茄果实产量,促进了番茄植株对土壤氮素吸收利用,显著提高了番茄营养品质。适量减量追氮及再生水灌溉交互作用保证了番茄产量、促进了番茄果实品质改善。Field experiments were carried out to analyze tomato yields, partial factor productivity for N, nitrogen in plant and fruit, vitamin c, organic acid, soluble sugar and sugar-acid ratio in order to study the effects of reducing nitrogen topdressing under reclaimed water irrigation on quality and yield of greenhouse tomato. The results indicated that reducing nitrogen topdressing moderately under reclaimed municipal wastewater irrigation increased tomato yield significantly, promoted soil nitrogen utilization of plant, and improved nutritional quality of tomato compared with tap irrigation. Interaction of reducing nitrogen topdressing moderately and reclaimed municipal wastewater irrigation ensured the tomato yietd and improved the fruit quality.
