摘要: 通过田间小区试验分析探讨了水稻高蛋白高产栽培综合技术体系、三壮三高栽培法、常规栽培法对湘丰早119(早稻)和培两优288(晚稻)稻米蛋白质和氨基酸含量的影响。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促进灌浆中后期水稻功能叶和籽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、赖氨酸、苏氨酸、蛋氨酸、人体7种必需氨基酸、猪11种必需氨基酸、鸡14种必需氨基酸和蛋白质含量、产量和蛋白质产量;能促进水稻功能叶、籽粒中谷草转氨酶和天冬氨酸激酶活性和提高糙米蛋白质产量。研究说明,水稻高蛋白高产栽培综合技术体系能满足高蛋白饲料稻高产优质栽培的需要。

Abstract: In order to compare influence of three different cultivation methods(integrated high yield cultivation system-IC,Sanzhuang Sangao cultivation system-SC and Conventional cultivation system-CC) on amino acid content of high protein forage rice grains,field experiments combining with laboratory analysis were conducted in 2004 in Langli County of Changsha City.The rice types provided for the experiments were Xiangfengzao119(early rice) and Peiliangyou288(late rice).and three cultivations methods were high-protein and high-yield integrative cultivation(HPHYIC),san-zhuang-san-gao cultivation(SZSGC) and conventional cultivation(CC).The Glutamicoxalacetic transaminase(GOT) and aspartokinase(AK) activity of leaves and grains,and the contents of protein and amino acid in brown rice were analyzed.The results showed that the activities of GOT and AK in functional leaves and grains,the contents of amino acid,lysine,threonine and methionine,seven kinds of essential amino acids for people,eleven of essential amino acids for pig,fourteen kinds of essential amino acids for chicken,protein and protein yield in brown rice were significantly improved by IC method compared with those of conventional cultivation and SC method.The IC method was suitable for high protein forage rice cultivation.
