摘要：

为推进江西省“籼改粳”战略,满足赣北地区种植粳稻的生产需求,增加农民收入和农业生产效益。本试验选择江西省农业科学院水稻研究所选育的4个常规粳稻品种,以赣宁粳1号为对照品种,在相同田间管理条件下,综合比较生育期、分蘖性、农艺性状、产量构成因素和产量。试验结果表明,21Q251各种生产表现不佳,不建议推广种植;21Q216表现出分蘖力强、成穗率高、结实率高、熟期转色好、抗病性较强,产量水平略低的特点,建议继续进行栽培实验时,应有足够的基本苗,早施分蘖肥,以确保有足够的有效穗数;赣晚粳688有较好的高产稳产表现,具有分蘖力强、成穗率高、结实率高、熟期转色好、抗倒伏性强、抗病性较强的特点,建议在赣北地区推广种植。

Abstract:

In order to promote the strategy of “change from indica to japonica”in Jiangxi Province, meet the production demand of japonica rice in northern Jiangxi Province, and increase farmers' income and agricultural production efficiency, in this experiment, four conventional japonica rice varieties bred by the Rice Institute of Jiangxi Academy of Agricultural Sciences were selected, and Ganningjing 1 was selected as the control variety. Under the same field management conditions, the growth period, tillering, agronomic traits, yield components and yield were comprehensively compared. The results showed that 21Q251 had poor production performance and was not recommended to be popularized. 21Q216 showed the characteristics of strong tillering ability, high heading rate, high seed setting rate, good color transformation at ripening stage, strong disease resistance, and slightly low yield level. It is suggested that basic seedlings should be inserted enough and tillering fertilizer should be applied early to ensure sufficient effective panicle. Ganwanjing 688 has good high yield and stable yield performance, showing strong tillering ability, high heading rate, high seed setting rate, good color transformation at ripening stage, strong lodging resistance and disease resistance, so it is recommended to be popularized in northern Jiangxi Province.
