| 摘 要： | 选用蚁酸钙制剂(CFA)、氯化钙制剂(CCOA)、硝酸钙制剂(CNOA)、丙酸钙制剂(CPA)、氯化钙(CaCl2)、硝酸钙犤Ca(NO3)2犦六种钙化合物对红富士苹果进行了疏花疏果试验。结果表明,以浓度为5～10g/L的蚁酸钙制剂效果最好;喷布两次比一次效果好,第一次在顶芽中心花盛开3d后喷布,第二次在顶芽中心花盛开5d后喷布,这样可确保顶芽中心花不受影响,而使顶芽侧花和腋芽花的结果率同时降低。CFA加用1mL/L的界面活性剂KP-4714,可显著提高疏花效果。所用钙化合物的疏花喷布对幼果生长和成熟果的大小、着色程度、果实品质均无不利影响。浓度为10g/L的氯化钙和硝酸钙处理对新梢生长点和幼叶有药害发生。 |

| Abstract: | The chemical thinning of Fuji apple with6calcium compounds,including agents of calcium-formic acid com-pound(CFA),calcium chloride-organic acid compound(CCOA),calcium nitrate-organic acid compound(CNOA),calci-um-propionic acid compound(CPA),calcium chloride(CaCl 2 ),and calcium nitrateCa(NO 3 ) 2 ]were used for Fuji apples flow-er thinning.Results showed that CFA at5～10g /L was the most effective treatment,and twice spraying was better than once spraying.The first effective spraying time was on the3rd day after central flowers of the terminal buds in full bloom,and the second time was at the5th day after the central flowers of the terminal buds in full bloom.By this way,the central flowers of terminal buds were not thinned,but fruit set rate of lateral flowers in terminal buds and flowers of the axillary buds were no-tably reduced.Spraying CFA mixed with surface-active agent KP-4714at1mL/L resulted in significant improvement of flower thinning.No negative effect from all the calcium compound spraying was observed concerning growth of young fruit and size,quality,coloring of maturing fruit.But the spraying with CaCl 2 and Ca(NO 3 ) 2 at10g /L resulted in chemical injury to young leaves and growth point of current shoots. |
