中文摘要	通过田间小区试验,研究在甜瓜配方施肥中减少化肥用量、添加肥料长效剂NAM对甜瓜生长、养分吸收和甜瓜产量、品质及经济效益的影响,以期为河西走廊沙漠绿洲灌区甜瓜栽培化肥减施提供依据。结果表明,与常规施肥相比,氮磷钾肥料纯养分用量减少20.6%~49.2%、配施NAM,不仅可以实现甜瓜生育期无追肥、一次性施肥,甜瓜平均产量及干物质累积量与常规施肥无显著差异,且甜瓜的可溶性固形物含量(SSC)显著增加,氮肥养分利用率提高1.23%~ 10.92%,经济效益也显著提高;其中氮磷钾肥料用量N 200 kg hm~(-2)、P_2O_5 100 kg hm~(-2)、K_2O 70 kg hm~(-2)、NAM0.6%处理(SF2)效果最佳,该配方可在河西走廊沙漠绿洲灌区甜瓜种植过程中推广应用。
英文摘要	A field experiment was carried out to study the effects of adding long-acting fertilizer NAM and reducing fertilizer application rate on the growth, nutrient absorption, yield, quality and economic benefit of melon in the desert oasis irrigation area of the Hexi Corridor.The results showed that there was no significant difference in the average yield and dry matter accumulation of melon between the treatments of reducing the pure nutrient input amount of NPK fertilizers by 20.6%-49.2% combined with adding NAM without top dressing and conventional fertilization treatment.And these treatments significantly increased the soluble solid content (SSC)of melon, the nutrient utilization rate of N fertilizer by 1.23%-10.92%, and its economic benefit compared with the conventional fertilization treatment.The best application effect was found in the treatment of SF2 formula fertilizer with the ratio of N: P: K of 1: 0.50: 0.35, and the amounts of N, P, and K fertilizers and NAM were N 200 kg hm~(-2), P_2O_5 100 kg hm~(-2), K_2O 70 kg hm~(-2)and NAM 0.6%.This formula fertilization should be promoted in the melon planting in the desert oasis irrigation area of the Hexi Corridor.
