适宜宁化县作烟后稻栽培的优质新品种筛选

Screening of the New Varieties with High Quality Suitable for Being Plantedas Post-tobacco Rice in Ninghua County

为筛选出适宜宁化县种植推广的烟后稻新品种,2022年宁化县引进华浙优223、平两优丝苗、乾两优馥香占、榕夏两优676等18个优质水稻新品种,以晶两优534为对照品种(CK),开展品种筛选试验,考察各水稻品种的生育期、产量、主要农艺性状、抗逆性等指标。结果表明:荃两优087产量为10543.5 kg·hm^(-2),比对照增产14.1%;晶两优8612产量为10437.0 kg·hm^(-2),比对照增产13%;明兴两优164产量为10384.5 kg·hm^(-2),比对照增产12.4%;荃两优1606产量为10312.5 kg·hm^(-2),比对照增产11.6%;冠两优华占产量为10012.5 kg·hm^(-2),比对照增产8.4%;榕夏两优676产量为9891 kg·hm^(-2),比对照增产7.1%;雅5优明占产量为9811.5 kg·hm^(-2),比对照增产6.2%;这7个品种综合性状表现突出,适宜在宁化县作为烟后稻进行示范推广种植。

In order to screen out the new varieties of post-tobacco rice which were suitable for being planted in Ninghua County,18 new varieties of rice with high quality,such as Huazheyou 223,Pingliangyousimiao,Qianliangyoufuxiangzhan,and Rongxialiangyou 676,were introduced into Ninghua County in 2022.By taking Jingliangyou 534 as the control variety(CK),the variety screening test was carried out to investigate the indicators of each rice variety,such as the growth period,yield,main agronomic characters and resistance,etc.The results showed that:The yield of Quanliangyou 087 was 10543.5 kg·hm^(-2),which was 14.1%higher than that of the control group.The yield of Jingliangyou 8612 was 10437.0 kg·hm^(-2),which was 13% higher than that of the control group.The yield of Mingxingliangyou 164 was 10384.5 kg·hm^(-2),which was 12.4% higher than that of the control group.The yield of Quanliangyou 1606 was 10312.5 kg·hm^(-2),which was 11.6% higher than that of the control group.The yield of Guanliangyouhuazhan was 10012.5 kg·hm^(-2),which was 8.4% higher than that of the control group.The yield of Rongxialiangyou 676 was 9891.0 kg·hm^(-2),which was 7.1% higher than that of the control group.The yield of Ya 5 Youmingzhan was 9811.5 kg·hm^(-2),which was 6.2% higher than that of the control group.These seven varieties had outstanding comprehensive characters and were suitable for demonstration and promotion planting as the post-tobacco rice in Ninghua County.
