| 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1～5d，最适喷布期是中心花盛开后1～3d；最适喷布浓度为15mol／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. Optimum concentration of spraying is 15 mol/L. It has no negative effect on fruit growth, fruit shape, fruit coloring and fruit quality. |
