【摘要】 依据国家标准GB/T1 7891 -1 999《优质稻谷》中的 8项涉及品种特性的品质性状指标 ,江西省主栽的杂交籼稻中 ,没有 1个组合达到国家标准 ,其主要原因是胶稠度、垩白度和垩白率不合格。主栽的常规稻品种中 ,只有一个早稻品种 (“湘早籼 31号”)和两个晚稻品种 (“赣晚籼 30号”和“赣晚籼 1 9号”)分别达到国家 3、3、2级优质稻谷标准 ,但没有一个达国家一级标准 ,差距表现在直链淀粉含量不是偏高就是偏低。因此 ,提出了加速江西优质稻开发的对策 ,即建立优质稻生产基地 ,发挥龙头企业的作用 ,实施优化栽培技术。更多还原

【Abstract】 On the basis of the quality indexes being related to varietal characteristics in the national criteria GB/T17891-1999 "High Quality Rice", none of main cultivated hybrid rice varieties (combinations) in Jiangxi reaches the national criteria, for their gel consistency, chalky degree and chalky rate are not qualified. Among main cultivated conventional rice varieties, only one early rice variety ("Xiangzaoxian 31") and two late rice variety ("Ganwanxian 30" and "Ganwanxian 19") reach Ⅲ,Ⅲ and Ⅱ grade of the national criteria respectively, but none of them reaches Ⅰ grade due to higher or lower amylose content. Therefore, the author put forward the following countermeasure for accelerating the development of high quality rice in Jiangxi province: constructing the base of high quality rice production, bringing the role of handlebar enterprise into play and carrying out superior cultural practices.更多还原
