The invention discloses the application of rice quality index in the identification of the first season rice and the regenerated rice rice. The quality indexes of the first season rice and the regenerated rice in the regenerated rice are detected by the conventional methods to determine the chalkiness, chalkiness and amylose content in the grain of the first season and the reclaimed season rice. There was significant difference between the value of the amount and the value of alkali elimination and the index value of the grain of the first season rice, and the index value of chalkiness and chalkiness was obviously lower than that of the first season rice, and the index value of amylose content and alkali elimination value was obviously higher than that of the first season rice. The invention can accurately identify the rice in the first and the second seasons of the ratoon rice, and the method is simple and the determination cost is low. The technical measures of the invention can be widely applied to different rice ecological zones to identify the first and the second season rice.

稻米品质指标在鉴别再生稻头季稻米和再生季稻米中的应用
本专利技术属于农作物领域，更具体涉及稻米品质指标在鉴别再生稻头季稻米和再生季稻米中的应用。
技术介绍
再生稻是通过相应的田间管理措施，使头季收割后稻桩上的休眠芽萌发、抽穗、开花结实而再次收获的水稻种植模式。再生稻具有投入产出率高、劳动效率高、省工、省种、节水等特点。是我国南方稻区种植一季稻热量有余而种植双季稻热量又不足的地区及双季稻区只种一季中稻的稻田提高复种指数，增加单位面积产量和经济收入的有效措施之一。因此，发展再生稻对适应当前农业结构调整、提高粮食产量、确保粮食安全和增加农民收入具有重要意义。近年来随着水稻品种改良和栽培管理措施的提高，再生稻头季和再生季产量都有了很大幅度的提高。另外，大量的研究表明，再生季稻米品质高于头季，一般可以达到国标优质米二级或者一级。基于优质再生季稻米良好的经济效益，很多农业合作社和农民都积极扩大再生稻种植。比如，湖北洪湖春露农作物种植专业合作社联合社再生稻种植面积达到8万亩，同时还向农业部申请“洪湖再生稻”地理标志。在很多再生稻产区，再生季水稻收购价格高于头季。随着再生季稻米带...

稻米品质指标在鉴别再生稻头季稻米和再生季稻米中的应用，所述的稻米品质的指标包括：垩白粒率，垩白度，直链淀粉含量和碱消值。
【技术特征摘要】
1.稻米品质指标在鉴别再生稻头季稻米和再生季稻米中的应用，所述的稻米品质的指标包括：垩白粒率，垩白度，直链淀粉含量和碱消值。2.根据权利要求1所述的应用，所述的再生稻的头季稻米和再生季稻米的判定标准为：再生季稻籽粒中垩白粒率，垩白度，直链淀粉含量和碱消值与头季稻籽粒中的指标值具备显著性差异，且垩白粒率，垩白度的指标值明显比头季稻米低，直链淀粉含量和碱消值的指标值明显比头季稻米高。...
