随着小麦产量水平的不断提高，对如何适应高产栽培、系统合理科学运筹肥料的要求更高。本试验从高产栽培要求出发，研究氮肥运筹的科学性、合理性，前、中、后期不同调氮技术以及磷钾配施对小麦生长的影响，以期为大面积小麦高产栽培积累科学依据。１试验设计１．１供试品种“
With the continuous improvement of the level of wheat production, it is more demanding to systematically and rationally develop fertilizer to adapt to high-yielding cultivation. Based on the requirements of high-yielding cultivation, this study studied the science and rationality of nitrogen fertilizer operation, the effects of different nitrogen application technologies in the early, middle and late stages and the effects of phosphorus and potassium on the growth of wheat, in order to accumulate scientific basis for high-yielding cultivation of large-area wheat. A trial design 1.1 test varieties "
