Abstract：Using 6 year-old Cerasus humilis cultivar ‘Nongda 4’ as material, different concentrations of 3 kinds of chemical flower thinning agents were sprayed at full -bloom stage .The fruit setting rate , yield and quality (sugar and acid content) were determinated.The results showed that spraying 1.0 Be°lime sul-phur significantly increased the mean single fruit weight and soluble solid content .Meanwhile , the mean fruit weight per branch and titrable acid content were also increased .Spraying 20 mg/L NAA or 10 .0 g/L Shiyile also had better effects.In conclusion, spraying 1.0 Be°lime sulphur at full -bloom stage was suitable for flower thinning of Cerasus humilis.
