田间试验研究不同氮用量对花生生长、养分吸收、产量和品质的影响。结果表明：在O～120kg／hm^2范围内，随着施氮量增加，花生荚果数增加，产量提高。120kg／hm^2用量下，花生产量最高3639．88kg／hm^2，比不施氮肥增产18．61％。0～150kg／hm^2范围内，施氮量提高促进氮磷钾吸收和植株生长及粗蛋白含量。150kg／hm^2用量下，花生蛋白质含量最高为27．00％，比不施氮肥提高了6．77％。超过150kg／hm^2，增加施氮量导致花生养分吸收减少，荚果数下降，蛋白质、粗脂肪含罱和产量随乡下隆。

Effects of nitrogen application on the growth, yield and quality of peanut were studied in field experiments. The results showed that the yield of pods increased along with nitrogen amount increases when application amount was less than 120 kg/hm^2. The highest yield was 3639.88 kg/hm^2 and increased by 18.61% as compared with control when the amount of applied nitrogen was 120 kg/ hm^2. Under 0~150 kg/hm^2 nitrogen fertilizer rate, applying nitrogen fertilizer could promote their absorption of N, P and K, regulate the transportation and distribution of nutrients in peanut plants, increase the protein content in the kernel. The highest protein content was 27.00% and increased by 6.77% when the amount of applied nitrogen was 120 kg/hm^2. The absorption of N, P, K and the yield of peanut were decreased obviously when the amount of applied nitrogen was over 150 kg/hm^2.
