摘　　要：为研究不同播期下功能肥对直播水稻产量的影响,探索功能肥在不同播期下的最佳增产效应,筛选出最合适的播期和功能肥组合,以C两优919和川作6优178为试验材料,设置3个播期,播期分别为B1(5月16日)、B2(5月23日)、B3(5月30日),4种功能肥分别用T1、T2、T3、T4表示,以喷施清水为对照进行试验。结果表明,2个水稻品种的全生育期随着播期延迟缩短,不同功能肥对不同播期的C两优919的产量、有效穗数、穗粒数、千粒重、结实率有显著影响;对川作6优178的产量、有效穗数、穗粒数有显著影响,而对千粒重和结实率无显著影响。C两优919在播期B2和功能肥T3组合下的增产效果最明显,产量最高,为12.09 t/hm^(2);而川作6优178在播期B3和功能肥T3组合下增产明显,产量最高,为12.59 t/hm^(2)。综上所述,T3功能肥对2个品种都有显著的增产效果,是因为T3处理主要增加了杂交稻的穗粒数,说明功能肥有利于水稻增产。In order to study the effect of functional fertilizers on the yield of direct-seeded rice at different sowing dates,explore the best yield increasing effect of functional fertilizers at different sowing dates,screen the most suitable sowing date and functional fertilizer combination,and use C Liangyou 919 and Chuanzuo 6 You 178 as experimental materials.Three sowing dates were set,namely B1(May 16),B2(May 23),and B3(May 30),and the four functional fertilizers were represented by T1,T2,T3,and T4,respectively.Spraying water was used as a control for the experiment.The results showed that the full growth period of the two rice varieties shortened with the delay of sowing date.Different functional fertilizers had an impact on the yield and effective number of panicles of C Liangyou 919 at different sowing dates.The number of grains per spike,thousand grain weight,and seed setting rate had a significant impact;there was a significant impact on the yield,effective number of spikes,and number of grains per spike of Chuanzuo 6 You 178,while there was no significant impact on thousand grain weight and seed setting rate.The yield increase effect of C Liangyou 919 was most significant under the combination of sowing date B2 and functional fertilizer T3,with the highest yield reaching 12.09 t/hm^(2);Under the combination of sowing date B3 and functional fertilizer T3,the yield of Chuanzuo 6 You178 increased significantly,reaching the highest yield of 12.59 t/hm^(2).In summary,T3 functional fertilizer has a sig-nificant yield increasing effect on both varieties,because T3 treatment mainly increases the number of grains per panicle in hybrid rice,indica-ting that functional fertilizer is beneficial for rice yield increase.
