AbstractBased on rice seedling monitoring data during 2O21-2O23 from Shouxian，Anhui Province，the effects of diffrentcultivation methodsonricegrowth，yield，and economic benefitswere analyzed.Theresults showed that in 2022 the rice growing season exhibited higher temperatures，less rainfall，which was conduciveto the accumulation of photosynthetic products，butthere might bearisk of high-temperature heat damage.Interms of planting structure，the areaof wheat-stubblericeincreasedannualy，whilethearea of vacant-stubblerice decreased.Mechanical transplanting anddirect seeding expanded continuously，whereas manual transplanting declined significantly.Variety selection became more concentrated and high quality，with a reduced number of main varieties and increased planting concentration.Theperennial sowing period ocurred around June 5.Seedling monitoring revealed that interannual meteorological conditionsand sowingdates significantlyinfluenced rice growth.In 2O22，optimal temperatureand light conditions resulted in higher stem and tiler numbers and leaf age，shortening the growth period by5-7days.In 2023， constraied by climateand waterresources，seedling indicators were generally weaker.In terms ofeconomic traits， mechanical transplantingachievedthehighest theoretical yield（ 11076.2kg/hm2 ），whiledirect seedingyielded the lowest （8 .Benefit analysis indicated that mechanical transplanting generated higher returns （12 249.1yuan/hm2）than manual transplanting （12 004.0 yuan/hm2），while directseeding （6 558.0 yuan/hm2） performed poorly.Inconclusion，optimizing crop succession layouts，promoting mechanical transplanting and high qualityvarieties，and adapting field management are efective strategies for enhancing rice yield and economic benefits in this region.
