摘要
通过对津川1号的不同播种期试验,比较分析了处理间产量、产量构成要素及品质食味的差异性,以期为优质水稻品种津川1号选择合理的播种时期提供理论指导。结果表明:津川1号的适宜播种期为4月中下旬,过晚,不仅产量会显著降低,而且会增加直链淀粉含量、降低粘性,进而降低其食味品质。
Through the different sowing date experiments on Jinchuan No.1, the differences of the yields, the yield composition elements and the eating qualities are compared and analyzed among the different treatments, and thus to provide theoretical guidance for choosing reasonable sowing period for high quality rice Jinchuan No.1. The results indicate that the suitable sowing time for Jinchuan No. 1 is in mid to late April, and the significant yield decrease, the amylose contents increase and the viscosity decrease can be induced because of the too late sowing time, and thus the eating qualities are reduced.
