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。
In order to screen good direct seeding rice varieties planted in Yinbei Irrigation Area of Ningxia and accelerate the replacement of rice varieties, 9 rice cultivars were used as materials in the comparative study of large areas in Nanliang Farm of Ningxia Land Reclamation Bureau. The growth period, the emergence rate, the dynamic of stem and tillering, the percentage of spike, the main economic traits, the yield and the quality were investigated. The results showed that under the same management conditions, Ningjing 41 and Jingning 32 had moderate growth period, high spike rate, prominent economic traits, high yield and large production potential, which had a good popularization and application value. Although the agronomic traits of G19 were worse than those of the control varieties, the processing quality and appearance quality of G19 were much better than those of the other tested varieties. As the promotion of high quality rice varieties, G19 had great potential.
