摘　　要：本研究旨为探究5.8%苄氨基嘌呤·萘乙酸悬浮剂对红富士苹果树花序坐果率和产量的影响,并评估其在实际生产中的经济效益。以红富士苹果树为试材,采用茎叶喷雾法施药,5.8%苄氨基嘌呤·萘乙酸悬浮剂施药浓度设800倍液、600倍液、450倍液、338倍液4个处理,以2%苄氨基嘌呤可溶液剂500倍液、5%萘乙酸水剂1 667倍液、40%乙烯利水剂1 333倍液(当地常规药剂)、人工疏果和空白处理为对照组,比较了5.8%苄氨基嘌呤·萘乙酸悬浮剂不同浓度处理对苹果树花序坐果率、果形指数、单果重和产量的影响。结果表明:与对照组相比,5.8%苄氨基嘌呤·萘乙酸悬浮剂处理可显著提高花序坐果率、单果率、双果率,增加果实横径、果实纵径以及果形指数,进而提高单果重和产量,其中5.8%苄氨基嘌呤·萘乙酸悬浮剂450倍~338倍液处理效果较好。从经济性角度考虑,450倍液处理在提升产量和果实品质的同时,也展现了较好的成本效益。合理使用5.8%苄氨基嘌呤·萘乙酸悬浮剂可以作为提高红富士苹果品质和产量的有效手段,为农民增收提供了新的策略。The aim of this study is to investigate the effect of 5.8%benzylaminopurine·naphthylacetic acid SC on the fruit setting rate of inflorescence and yield of Red Fuji apple,and evaluate its economic benefits in actual production.Red Fuji apple trees were used as the materials.Agents were sprayed on stem and leaf.The concentration of 5.8%benzylaminopurine o naphthylacetic acid SC was 800,600,450 and 338 times,taking 500 times of 2%benzylaminopurine SL,1667 times of 5%naphthylacetic acid AS,1333 times of 40%ethephon AL(local conventional agent),artificial fruit thinning and blank treatment as the controls.The results showed that compared with the control groups,the treatment with 5.8%benzylaminopurine·naphthylacetic acid SC significantly improved the fruit setting rate of inflorescence,single fruit rate,double fruit rate,fruit transverse diameter,fruit longitudinal diameter,and fruit shape index,thereby increasing single fruit weight and yield.Among them,the treatment with 5.8%benzylaminopurine·naphthylacetic acid SC at 450-338 times had the best effect.In view of economy,5.8%benzylaminopurine·naphthylacetic SC at 450 times could not only improve the yield and fruit quality,but also has good cost-effectiveness.The reasonable use of 5.8%benzylaminopurine·naphthylacetic acid SC can be an effective mean to improve the quality and yield of Red Fuji apples,providing a new strategy for increasing farmers’income.
