摘要： 探讨了MCPB-ethyl的喷布时期、喷布浓度对富士苹果的疏花效果、果实发育和果实品质的影响.试验证明,MCPB-ethyl是一个良好的苹果疏花剂,有效喷布期是中心花盛开后1～5 d,最适喷布期是中心花盛开后1～3 d:最适喷布浓度为15 mol/L,对果实发育、果形、果实着色和果实品质无不利影响.

Abstract: In this study, thinning flowers effect, time and concentration of spraying, and influence on fruit growth and quality in Fuji apple were tested with MCPB-ethyl. It was proved that MCPB-ethyl is a qualified flower thinner of apple. In addition, the follow problem were known:Effective spraying time is at 1-5 days after king flower full bloom, optimum spraying time is at 1-3 days after king flower full bloom.
