摘 要 ：试验研究玉米-花生混作对系统内N营养的影响结果表明，种植密度花生∶玉米=5∶3混作对玉米、花生单株生物量、植株全N及单株吸N量均无明显影响，但显著降低混作花生根际土壤NO^-₃-N浓度，同时显著增加混作花生根瘤数，提高单株根瘤固N酶活性。

Abstract:Effects of mixed cropping of maize and peanut on the N nutrition in cropping system were studied.The results indicate that mixed cropping density of maize and peanut(peanut∶maize=5∶3)has no significant effects on biomass,total N and N uptake per plant of maize and peanut,but can obviously reduce NO^-₃-N concentration in the rhizosphere of peanut and improve peanut nodule number and peanut nodule nitrogenase activities(ARA)per plant peanut.
