稻米蛋白质含量比较低,一般为8%左右。近年来,通过杂交选育、辐射诱变等方法,培育出了一些蛋白质含量较高的品种。但是,稻米蛋白质含量受环境因素的影响很大,氮肥施用量、施肥时间、水分管理等栽培技术以及土壤、气候条件均影响蛋白质含量。因此,提高稻米蛋白质含量,不仅与育种 Rice protein content is relatively low, usually about 8%. In recent years, through breeding methods such as hybridization, radiation mutagenesis and other methods, breed some higher protein varieties. However, the protein content of rice is greatly affected by environmental factors. The nitrogen application rate, fertilization time, water management and other cultivation techniques and soil and climatic conditions all affect the protein content. Therefore, improving rice protein content, not only with breeding
