AbstractThe planting performance of Zhuliangyou 5298 was combined in Anqing City,Anhui Province area,and its high yieldcultivation techniques weresummarized.From2022 to2024,this variety was plantedin12demonstration sites,including Wangjiang County in Anqing City,withan upright and upward curved plantshape;thegrowth period was l30-136 days,with an average seed setting rate of 85.77% ,a thousand grain weight of 24.1 g,and a yield of 8 280- 9000kg/hm2 ; good polishedrice yield and excellent ricequality;stronganti lodgingability.Itshigh yield cultivation techniques include early sowing (sowing and seedling cultivation from late April to mid May),timelytransplanting, cultivating strong seedlings，keeping thesoil of the seedling field moist，applying“weaning fertilizer”(urea 60- 75kg/hm2 ）according to the growth of the seedlings,and timely prevention and control of seedling diseases and pests such as ricethrips and bakanae disease; select high speedrice transplanter operation basedonseedling quality,planting time,etc.,inspectanddebugthe transplanting machineryaccording tothesetings,determinetheplantingdistance, seedling amount,and depth; timely weed control (spraying pesticides such as butachlor for soil sealing，spraying pesticides such as butazone for stemand leaf control during the seedling stage,and spraying pesticides such as 30% （202 propiconazole for sealing throughout the field after the seedlings);heavy application of base fertilizer ( 45% compound fertilizer 450-600kg/hm2 ),early application of tillering fertilizer (high nitrogen and high potassium compound fertilizer 225-300kg/hm2 ),and supplementary application of ear fertilizer (potassium chloride 112.5-150.0kg/hm2 ); shallow water seedling planting,deep water live planting,alternatingdryand wetconditions to promote tilering;appropriate pesticides should be usedduring the growth period of the field to prevent and control diseases and pests such as rice blastandsheath blight.Thisarticle providesareference for further promotionand plantingofthisvarietyin similar regions.
