2019年永定区杂交水稻晚季新品种筛选试验

摘 要：为了筛选出适宜福建省龙岩市永定区种植的晚稻品种，2019年永定区引进了韶优766、万象优111、万象优982、昌两优8号、粳香优巴丝等5个杂交水稻新品种，在金砂乡西田村围屋段进行品种筛选试验，以中浙优8号为对照，考察各水稻品种的生育期、适应性、产量、抗逆性、株叶形态等农艺性状。结果表明：韶优766产量显著高于对照，粳香优巴丝和昌两优8号产量略高于对照，这3个品种建议继续扩大示范面积，进一步观察各品种农艺性状、适应能力及抗逆性等;万象优111和万象优982产量不及對照且抗病能力较弱，生育期较短、熟期早，不建议在永定区推广种植。

Abstract： In order to screen out the varieties of late rice suitable for being planted in Yongding District of Longyan City in Fujian Province， five new varieties of hybrid rice， including Shaoyou 766， Wanxiangyou 111， Wanxiangyou 982， Changliangyou 8 and Jingxiangyoubasi， were introduced into Yongding District in 2019. Then， the variety screening test was carried out in the round house section of Xitian Village in Jinsha Township， and Zhongzheyou No.8 was used as the control group to investigate the agronomic traits of various rice varieties， such as the growth period， adaptability， yield， stress resistance， plant and leaf types， etc. The results showed that the yield of Shaoyou 766 was significantly higher than that of the control group， and the yield of Jingxiangyoubasi and Changliangyou No.8 was slightly higher than that of the control group. Therefore， the three varieties were suggested to continue to expand the demonstration area， in order to further observe the agronomic traits， adaptability and stress resistance of each variety. The yield of Wanxiangyou 111 and Wanxiangyou 982 was lower than that of the control group， and had weak disease resistance， short growth period and early ripening period， so they were not recommended to be planted widely in Yongding District.

永定区地处福建省西南部，位于东经116°25′～117°05′，北纬24°23′～25°05′，海拔高度69～1547 m，年平均日照2024.6 h，年降水量1606.9 mm，境内各地气候主要受海拔和地形地势的影响，地势东南低，西北高，垂直变化较为明显。全区耕地面积约2.2万hm2，大都属于丘陵山地，以种植水稻为主。主要栽培模式六月红芋-稻、烟-稻、菜-稻-稻及高海拔山区的单季稻或中稻;水稻主栽品种为中浙优8号[1]。中浙优8号在永定区种植已近10年，近年来，种植过程中出现了严重的白叶枯病，急需品种更新换代。为筛选出适合永定区域范围内生产条件和市场需求的主导品种，促进永定区水稻新品种推广应用，优化品种布局，促进种植业结构调整[2]。2019年晚季永定区引进了韶优766、万象优111、万象优982、昌两优8号、粳香优巴丝等5个晚稻新品种，以中浙优8号为对照进行品种筛选试验。……
