试验以6年生‘农大4号’欧李为试材，于盛花期分别喷施不同浓度的3种疏花剂，测定植株坐果率、成熟期果实产量及糖酸含量。结果表明：喷施1．0 Be°石硫合剂可显著提高平均单果重和可溶性固形物含量，平均单枝果重和可滴定酸含量也有提高。喷施20 mg/L萘乙酸或10．0 g/L的施易乐效果较好。建议在欧李盛花期喷施1．0 Be°石硫合剂进行疏花。

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.
