摘　　要：[目的]为探究花生在不同钙素水平下氮代谢特点。[方法]选用606为试验材料,钙素设4个水平,测定不同生育时期主要氮代谢酶(硝酸还原酶(NR)、谷氨酰胺合成酶(GS)、谷氨酸合成酶(GOGAT)和谷氨酸脱氢酶(GDH))活性及各叶片、茎秆和籽仁中蛋白质含量。[结果]施用钙肥不仅提高花生不同生育时期叶片中NR、GS、GOGAT和GDH活性,而且促进花生植株对氮素的吸收,增加籽仁中蛋白质含量。[结论]施钙量为300 kg/hm2时,效果最好。[Objective] The experiment aimed to study the nitrogen metabolism under different levels of calcium applying in peanut.[Method] Taken 606 as the test material,four different levels of calcium were set,and the main nitrogen metabolism enzyme （nitrate reductase （NR）,glutamine synthetase （GS）,glutamate synthase （GOGAT） and glutamate dehydrogenase （GDH）） activity at different growth stage and the protein content in leaves,stems,kernels were determined.[Result] The enzyme activity of NR,GS,GOGAT and GDH was significantly increased by the application of calcium at different growth stage.The application of calcium fertilizer improved the absorption of nitrogen in peanut and the protein content in the seed kernel.[Conclusion]300 kg/hm2 Ca had the best effect.
