不同土壤与海拔高度对谷子(粟)蛋白质氨基酸组成的影响

Effects of different soils and altitudes on the composition of amino acids in foxtail millet

  • 摘要: 用红土、黄土和红黄土3种土壤在不同海拔高度进行谷子优质栽培试验。结果表明,与红黄土相比,红土和黄土地种植的谷子籽粒蛋白质质量较高,主要氨基酸含量分别高25.4%和21.4%;必需氨基酸含量高23.2%和21.6%;除赖氨酸外其余氨基酸含量基本接近人体的需求量;氨基酸指数高21.5%和21.9%。在较高海拔高度种植的谷子蛋白质品质较优,1100~1200m比900~1100m海拔高度种植的谷子主要氨基酸含量高8.7%,氨基酸指数高7.8%。因此,谷子优质栽培适于在1100~1200m海拔高度的红土或黄土地种植为宜.

     

    Abstract: In order to develop the cultivation techniques for high quality of foxtail millet,the experiments were accomplished in red soil,loess soil,red-loess soil and different elevations.The results have proved that the quality of protein for millet grains grown in red soil and loess soil was high.The contents of main amino acid in grain of millet grown in red and loess soils were 25.4% and 21.4% highter than those in red-loess soil,the contents of essential amino acid were 23.2% and 21.6% highter.The essential amino acid indexes(EAAI) were increased 21.5% and 21.9%,respectively.The quality of protein for millet grains grown in high elevation was superior.The content of main amino acid for the millet grown at the altitude of 1100~1200m was 8.7% highter than that at 900~1100m,EAAI was increased 7.8%.Therefore,millet ought to be cultivated in red soil and loess soil at the altitude of 1100~1200m for getting high quality.
