摘要
通过粳稻新品种机插种植比较试验研究,结果表明,扬粳687、大粮203全生育期131～133 d,早熟;其余品种全生育期141～150 d,比扬粳687、大粮203迟熟10 d以上。早熟比迟熟品种产量相对要低,中稻1号产量最高,大粮203产量最低。中稻1号、淮稻5号、宁粳4号综合表现较好,适宜大面积推广,其余品种需扩大示范或再示范。
The test were made on the new varieties of mechanical transplanting japonica rice, and the results indicated that Yangjing687 and Daliang203 belonged to the early maturity varieties which whole growing period were 131-133 d, the other varieties can achieve 141-150 d. the yield of early maturity varieties is relatively lower, so Zhongdaol had the highest yield and Daliang203 were lowest. Zhongdaol, Huaidao5 and Ningjing4 had better comprehensive performance and suitable for large-area popularization and application.
