以天津市培育的优质小站稻品种津川1号和隆优619为供试材料,分析了春稻和麦茬稻品质特性的差异。结果表明,津川1号作麦茬稻的整精米率明显低于作春稻,而垩白粒率显著高于春稻;津川1号麦茬稻的蛋白质含量明显偏高,食味值显著低于春稻;隆优619作春稻和麦茬稻无论在外观、加工、食味还是营养品质方面均无显著差异,是较理想的麦茬连作品种。

The differences of quality characteristics between spring and wheat stubble rice were analyzed for Jinchuan 1 and Longyou 619 varieties. The results showed that the whole rice rate and the palatability score of Jinchuan 1 as wheat stubble rice were significantly lower than that as spring rice, the chalky grain rate and the protein content were significantly higher than that as spring rice. For Longyou 619, there was no significant difference in appearance, processing, palatability and nutritional quality between spring rice and wheat stubble rice, it was an ideal variety for continuous cropping of wheat stubble.
