摘要
为研究不同施氮量对红米杂交稻金农3优3号产量形成及氮肥利用的影响,2022年在延平区王台镇开展了氮肥不同用量田间试验。结果表明:金农3优3号的稻谷产量随着施氮水平的提高而增加;不同氮肥水平处理对有效穗数、每穗粒数与结实率等主要农艺性状均有影响;氮肥农学效率在施肥量之间的变幅较大,其中每667m^(2)施氮量12 kg处理的最高,达11.9,而施氮量10 kg处理的最低,为9.12。综合考虑产量、氮肥农学效率、经济效益等因素,金农3优3号在延平区种植推荐每667m^(2)施氮量以12 kg为宜。
Field experiment was conducted in Wangtai Town,Yanping Distract in 2022 to survey different nitrogen application effect on yield components and nitrogen utilization of Jinnong 3 You 3.The results showed that grain yield increased with the increase of nitrogen application,all of different nitrogen application treatments effect effective panicle number,spikelets number per panicle and seed setting rate.Nitrogen agronomic efficiency vary largely with nitrogen application treatmnets,the maximum treatment was nitrogen application 12 kg per 667m^(2),and reached 11.9,the minimum treatment was 10 kg per 667m^(2),and reached 9.12.The recommendation nitrogen rate was 12 kg per 667 m^(2)with comprehensively considered of yield,nitrogen agronomic efficiency and economic benefits.
