现有的研究表明,增施氮肥和后期追氮均能明显地增加小麦籽粒的蛋白质含量,提高籽粒的营养品质。但在高产条件下,如何经济有效地运筹肥料,在小麦高产的同时改善品质,达到高产优质的目的,这是生产上尚待解决的问题。为此,我所于1985～1987年设置了高产条件下等量氮肥不同运筹方式的试验,品种鲁麦7号,处理方法见表1。

The existing research shows that adding nitrogen fertilizer and late-stage nitrogen can significantly increase the protein content of wheat grain and improve the nutritional quality of the grain. However, under the condition of high yield, how to economically and efficiently make fertilizer and improve the quality of wheat while achieving high yield and good quality are the problems to be solved in the production. To this end, I set in 1985 to 1987 under the same conditions of different production methods of nitrogen fertilizer different operation of the test, the varieties of Luoma 7, treatment methods in Table 1.
