Combined application of N, Zn, Mn could not only increase the content of protein and total amino acid, but also raise the rate of the total essential amino acid in protein and improve the nutrition quality of wheat grain. N、Zn、Mn平衡施用既能增加小麦子粒蛋白质和氨基酸总含量,又提高了蛋白质中必需氨基酸的比例,改善了小麦子粒的营养品质。
The total amount of amino acid and essential : total ( EA / TA ) amino acid rations could be increased by spraying nitrogen with appropriate quantity at appropriate stage, thereby, the nutrition value of protein is raised. 适期适量叶面喷氮可以提高氨基酸总量及必需氨基酸含量与氨基酸总量的比率(EA/TA).从而提高蛋白质的营养价值。
