小麦是人类植物蛋白质最重要的来源之一,约占人类食物结构中热量和蛋白质总量的20％左右。目前小麦籽粒蛋白质含量较低,其蛋白质中对人体和非反刍动物必需的氨基酸组成很不平衡,尤以赖氨酸缺乏,为第一限制性氨基酸。 农产品品质的优劣,一方面取决于作物品种的遗传性,另一方面也取决于外界环境。小麦籽粒蛋白质含量的差异主要是环境的影响,在遗传上的差异只占较小的部分。因此,改善作物生长的环境条件,是可以从同样数量的收获物中得到营养价值较高的农产品;施肥的作用是改善植株的营养条件,目的在于增加农作物的产量,提高产品品质。在影
Wheat is one of the most important sources of human plant protein, accounting for about 20% of the total calories and proteins in the human food structure. At present, the grain protein content of wheat is relatively low, and the essential amino acid composition of the protein in human and non-ruminant animals is very unbalanced, especially the lack of lysine, which is the first limiting amino acid. The quality of agricultural products, on the one hand, depends on the heredity of crop varieties, on the other hand also depends on the external environment. The differences in the protein content of wheat grains are mainly environmental influences, with only minor differences in the genetic differences. Therefore, improving the environmental conditions of crop growth is to obtain the agricultural products with higher nutritional value from the same amount of harvests; the role of fertilization is to improve the nutritional conditions of the plants with the purpose of increasing crop yield and improving product quality.
