摘　　要： ＮａＮＯ３作基肥或始花后７天喷施５００ｍｇ／Ｌ调节膦均能提高花生叶片的呼吸速率、硝酸还原酶活性和根瘤固氮活性，增加叶片全氮含量．基肥施用（ＮＨ４）２ＳＯ４却降低了叶片硝酸还原酶和根瘤固氮活性，但叶片呼吸速率与全氮含量仍高于对照．处理的单株荚果产量和种子蛋白质含量均高于对照． Abstract Application of NaNO3 as base fertilizer or spraying Fosamine in 500mg/L. after peanut blossoming 7 days could promote nitrate reductase activity (NRA), respiration rate of leaves and nitrosen fixation of root nodules,and the nitrogen content in leaves increased.Although application of (NH4)2SO4 as base manure inhibited NRA of leaves and nitrogen fixation of root nodules, it raised the respiration rate and increased the nitrogen content of leaves. All treatments could increase individual plant productivity and protein content of seed.
