Abstract To explore the optimal application periodand operation mode of rice“one spray，multiple promotion” technology，thisstudyconductedfieldexperimentsinShijianTown，Wuwei City（siteA，cultivar：Weiliangyou8612）and Xuzhen Town，Nanling County （site B，cultivar： Huixiangjing 977） in Anhui Province.5treatments were established， treatment1（fullheading stage+knapsack sprayer）， treatment2（fullheading stage+plantprotectiondrone），treatment3 （grain filling stage+knapsack sprayer）， treatment 4 （grain filling stage ;+ plant protection drone），and treatment 5（control， conventional cultivation，not subjected to“one spray，multiple promotion”treatment）.The efects of each treatmenton rice growthperiod，grainquality，yield，andeconomicbenefits weresystematicalyanalyzed.Theresultsshowedhatthe application of the“one spray，multiplepromotion”technique had no significant impact on the ricegrowth cycle. Treatment4resulted insuperior grain quality traits.The effectivenumberof rice panicles in experimental sites Aand B was higher intreatment1，with 3.2502millionand3.5073 million panicles/hm，respectively.Treatment4had more grains per panicle， with181.0and121.2 grains，respectively.Yield performance varied between cultivars： Weiliangyou 8612 achieved the highest yield under treatment 1 （1 3114.8kg/hm2 ）， whereas Huixiangjing 977 achieved the highest yield under treatment 4 （9 684.0kg/hm2 ）.Economic benefitsalso differed between the two trial sites，site A showed higherreturnsunder treatment1（9 677.4 yuan/hm2），while site B showedhigher returns under treatment4 （5 231.1 yuan/hm2）.In summary，thecombinationof plant protection drone witha fixedagent mixtureappliedatthe full heading stage for indica riceand thegrain filing stage for japonicarice yielded beterresults.The findings provide a reference for optimizing the“one spray，multiple promotion” technical model in similar regions.
