摘　　要：以坐果率较高的枣油桃为试材,研究了乙烯利、萘乙酸、S-诱抗素、木醋液等4种化学疏花剂不同浓度处理对桃坐果率和果实品质的影响。结果表明,喷施500、1000 mg/L乙烯利和喷施677 mg/L S-诱抗素处理对枣油桃果实疏除效果明显。不同处理均提高了单果重,降低了果实可滴定酸含量。喷施乙烯利、S-诱抗素处理提高了果实可溶性固形物含量。从产量和果实品质方面综合考虑,喷施500 mg/L乙烯利、667 mg/L S-诱抗素进行疏果较适宜。The effects of four chemical flower thinning agents(ethephon,naphthalene acetic acid,S-abscisic acid and wood vinegar)at different concentrations on fruit setting rate and fruit quality of‘Zaoyoutao’nectarine with high fruit setting rate were studied.The results showed that the treatments of 500,1000 mg/L ethephon and 677 mg/L S-abscisic acid had obvious effects on the fruit thinning‘Zaoyoutao’nectarine.Different treatments increased the average single fruit mass and decreased the titratable acid content.Ethephon and S-abscisic acid treatments increased the soluble solids content.From the comprehensive consideration of yield and fruit quality,spraying 500 mg/L ethephon and 667 mg/L S-abscisic acid is suitable for fruit thinning.
