采用不同时期、不同浓度进行叶面喷施的方法 ,研究了金秋液肥对红富士苹果坐果及果实发育的影响。结果表明 ,初花期、落花期叶面喷施 1次 30 0～ 4 0 0倍及 2次叶面喷施 4 0 0倍金秋液肥 ,可使红富士苹果花朵坐果率提高 1 6 %～ 10 3% ,幼果显著增大 ,叶片厚度增加0 6 %～ 7 4% ,单位面积叶片重增加 2 6 %～ 10 6 % ,叶片光合作用速率提高 39 5%～ 56 6 % ,各处理均可显著提高单果重 ,坐果后处理可提高果肉硬度 ,2次及 3次处理可提高果实可溶性固形物含量 The effects of Jinqiu liquid fertilizer on the fruit setting and fruit development of Red Fuji apple were studied using foliar spraying at different periods and different concentrations. The results showed that the flower setting rate of red Fuji apple flower increased by 16% ~ 10 3 at the first flowering stage and at the stage of flowering and once at the flowering stage by 30 0-4 0 0 folds and twice foliar spray at 400 foliage. %, The young fruit increased significantly, the leaf thickness increased by 0.6% ~ 74%, the unit area increased by 26% ~ 106%, the leaf photosynthesis increased 39 5% ~ 56 6%, the treatment can be significant Improve the fruit weight, post-processing fruit can improve the hardness of the fruit, 2 and 3 times to improve fruit soluble solids content
