摘　　要：为了筛选出适宜在宁夏银北灌区种植的优良直播水稻品种,加速水稻品种的更新换代,以9个水稻品种为材料,在宁夏农垦南梁农场采用大区对比法进行比较试验,分别对各品种的生育期、出苗率、茎蘖动态和成穗率、主要经济性状、产量、品质等指标进行考察。结果表明:在相同管理条件下,宁粳41、京宁32的生育期适中,成穗率较高,经济性状突出,产量较高,生产潜力大,具有很好的推广应用价值。G19虽然农艺性状较对照品种差,但其加工品质和外观品质都远远优于其他供试品种,作为优质稻米品种推广有较大潜力。The purpose of this experiment was to screen good rice cultivars for direct seeding and promote the cultivar replacement and update in Yellow River irrigation region, The comparative experiment for nine direct seeding nce was carried out through interlaboratory comparison in Nanliang farm, and the growing stage, germination situation, tiller number, earing percentage, main economic character, yield and quality were recorded. The results showed that under the same management condition, the Ningjing 41 and Jingning 32 with proper growing period, high earing percentage, outstanding economic character, high yield and great potential productivity were fit for extension in this area. For G19, although the agronomic character was worse than control, the processing quality and appearance quality were superior to other test varieties, which had great promotional potential as good rice variety.
