摘　　要：在田间试验条件下研究不同氮肥用量对辐射选育的仁秆两用型花生叶片生理特性及产量、品质的影响。结果表明:氮肥的不同用量均可不同程度地提高仁秆两用型花生叶片光合速率和叶绿素含量,且在花生饱果期的作用大于结荚期,以N150、N300和N450处理效果最显著。不同的施氮量对提高叶片CAT酶活性、降低MDA积累量和增加可溶性蛋白质含量均有明显的作用,N300、N450处理的作用大于其他处理。合理的施氮肥量可明显提高花生荚果和花生秆的产量,以N300处理产量最高,其次为N150处理。施用氮肥150kg·hm-2可增加花生籽仁的赖氨酸、蛋氨酸等的含量,从而改善花生营养品质。The field experiment was conducted with peanut ＇shan G＇ as material, in the experimental station of Agricultural Ecology Institute, Fujian Academy of Agricultural Sciences to study the effects of N application amount on physiological characteristics, yield and quality of dual-purpose peanut. The results showed that different nitrogen fertilizer treatments increased chlorophyll content and photosynthetic rate in peanut leaves, with greater increasing extent at middle-later stage （pod filling stage） than that at the middle stage （pod setting stage）. Nitrogen application enhanced the activities of catlase （CAT） and the contents of soluble protein, but reduced malondialdeyde （MDA） content in peanut leaves, especially treated by N300 and N4s0. Nitrogen application led to the highest yields of peanut and peanut vine, and reached the highest when applying N 300 kg hm-2 level. In addition, the application of nitrogen fertilizer also increased the contents of lysine and methionine, which were inadequate in the protein fractions of peanut kernel, to improve nutritional quality of peanut.
