- 摘要:
- 为筛选出高产、优质、适合浏阳稻作区种植的水稻新品种，加快地域性优质稻的推广步伐。对2022年引进的5个水稻新组合进行品种比较试验，鉴定各品种的丰产性、抗逆性及适应条件。结果表明，参试品种中野香优莉丝、悦两优2646全生育期为133 d，乾两优馥香占全生育期为132 d，冠两优华占全生育期为131 d，云两优2118全生育期为129 d；所有参试品种叶姿直立或挺直，没有发生稻叶瘟病、稻穗瘟病和水稻纹枯病等病害；冠两优华占产量居首位，产量达597.83 kg·（666.67 m2）-1，其次是云两优2118，产量达582.33 kg·（666.67 m2）-1。悦两优2646、乾两优馥香占的产量分别达578.67和576.67 kg·（666.67 m2）-1，均显著高于对照。野香优莉丝的实际产量为542.83 kg·（666.67 m2）-1，与对照差异不显著。综上所述，这5个参试品种产量除野香优莉丝外，其余品种较为理想，可在浏阳市沿溪镇推广种植
- Abstract:
- In order to screen new rice varieties with high yield, high quality and suitable for planting in Liuyang rice planting area, and accelerate the promotion of regional high-quality rice. A variety comparison test was conducted on five new rice combinations introduced in 2022 to identify the high yield, stress resistance and adaptability of each variety. The results showed that the whole growth period of the tested varieties Yexiangyoulisi and Yueliangyou 2646 were all 133 days; The total growth period of Qianliangyoufuxiangzhan, Guanliangyouhuazhan and Yunliangyou 2118 was 132 days ,131 days and 129 days. All the tested varieties had upright or straight leaves, and there were no disease spots such as rice leaf blast, rice ear blast and rice sheath blight; Guanliangyouhuazhan ranks the first with the yield of 597.83 kg·(666.67 m2)-1, followed by Yunliangyou 2118 with the yield of 582.33 kg·(666.67 m2)-1; The yield of Yueliangyou 2646 and Qianliangyoufuxiangzhan respectively reached 578.67 and 576.67 kg·(666.67 m2)-1, both of them all significantly higher than the control; The actual yield of Yexiangyoulisi was 542.83 kg·(666.67 m2)-1, which was not significantly different from the control. To sum up, except for Yexiangyoulishi the yield of the five varieties tested is ideal, which can be popularized and planted in Yanxi Town, Liuyang City.
