水稻属于低蛋白作物,稻米的蛋白质含量与氨基酸组成受遗传基因的控制,但环境条件与栽培措施的影响也不容忽视.采用田间小区试验和室内分析相结合的方法,以湘早籼31(早稻)和培两优210(晚稻)组合为材料,探讨了水稻高蛋白高产栽培技术体系、三壮三高栽培法、常规栽培法对稻米氨基酸含量的影响及其作用机理.结果表明,与常规栽培法相比,水稻高蛋白高产栽培综合技术体系能明显提高灌浆中后期水稻功能叶和子粒中谷草转氨酶和天冬氨酸激酶的活性,明显提高糙米氨基酸、人体7种必需氨基酸和蛋白质含量、产量和蛋白质产量;除早稻蛋白质产量外,其他指标与三壮三高栽培法之间差异不显著.水稻高蛋白高产栽培技...

Rice is a low protein crop, and the protein content in rice grain is determined not only by its inherent gene, but also by environment factors （such as temperature, light and fertilization） and cultural methods. In this paper, the effects of 3 cultivation methods （high-protein and high-yield integrative cultivation method, San-zhuang-san-gao cultivation method and conventional cultivation method） on amino acid content of rice grains and preliminary study on its mechanism were conducted using the rice type of Xiangzaoxian 31 （early rice） a...
