田间试验结果表明,增施氮肥提高了小麦籽粒粗蛋白,各种氨基酸和湿面筋的含量,增加小麦容重。等量氮肥分期施用,降低了小麦籽粒产量,却提高了籽粒粗蛋白含量。增施磷肥,则降低籽粒粗蛋白含量。在高产施肥的基础上,适当增加氮肥用量和加大后期施氮比重,可达到高产优质. The results of field experiments showed that increasing nitrogen fertilizer increased the content of crude protein, various amino acids and wet gluten and increased the bulk density of wheat. The same amount of nitrogen application staged, reducing wheat grain yield, but increased grain crude protein content. Adding phosphate fertilizer, then reduce the crude protein content of grain. On the basis of high-yield fertilization, appropriate increase in the amount of nitrogen fertilizer and increase the proportion of late nitrogen, can achieve high yield and quality.
