美国南达科塔州大学土壤试验室主任Ron Gelderman说:“氮素是麦粒蛋白的主要来源,任何土壤含氮的水平都会影响麦粒蛋白的含量”。 Gelderman说:“过量的施氮,会使蛋白含量减少比产量减少的更多,在肥沃的田里与硝酸盐含量高的土壤施氮是得不偿失的。虽然高蛋白的小麦品种在任何氮素水平条件下,蛋白含量均高,但一些品种增加氮素会使它们增加蛋白的含量”。
Ron Gelderman, director of soil testing at the University of South Dakota, USA, said: “Nitrogen is the main source of grain protein and any soil nitrogen level affects grain protein content.” Gelderman said: “Excessive nitrogen application will reduce the protein content more than the yield reduction, in fertile fields and high nitrate content of soil nitrogen is worth the candle.Although high protein wheat varieties at any nitrogen level Conditions, the protein content are high, but some varieties increase nitrogen will make them increase the protein content. ”
