Effects of 5.8％Benzylaminopurine·Naphthylacetic Acid SC on Fruit Setting Rate of Inflorescence and Yield of Red Fuji Apple
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 ac-tual 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％ethep-hon 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 trans-verse 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 im-prove the yield and fruit quality,but also has good cost-effectiveness.The reasonable use of 5.8％benzy-laminopurine·naphthylacetic acid SC can be an effective mean to improve the quality and yield of Red Fuji ap-ples,providing a new strategy for increasing farmers'income.
