以豫农202为材料,在大田条件下,研究氮锌配施对冬小麦不同生育时期氮吸收的影响,并探讨氮锌配施对冬小麦氮素利用率、产量以及子粒蛋白质含量的影响。结果显示,氮锌配施能够促进冬小麦对氮素的吸收,与单施氮肥相比,氮锌配施的冬小麦在开花期、灌浆期吸收的氮素较高,成熟期小麦
The effects of nitrogen and zinc fertilizers on nitrogen uptake by winter wheat at different growth stages were investigated under field conditions, and the effects of nitrogen and zinc fertilization on the nitrogen use efficiency, yield and grain protein content of winter wheat were studied. The results showed that the combination of nitrogen and zinc could promote the nitrogen absorption of winter wheat. Compared with the single application of nitrogen and nitrogen, winter wheat with nitrogen and zinc application had higher nitrogen uptake during the flowering and filling stages and the mature wheat
