金秋液肥对红富士苹果坐果及果实发育的影响

EFFECTS OF “JINQIU” LIQUID FERTILIZER ON FRUIT SETTING AND FRUIT DEVELOPMENT OF RED FUJI APPLE

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

Using the method of foliage spray in different time and with various concentrations, the effects of“Jinqiu”liquid fertilizer on fruit setting and fruit development of Fuji apple are studied The results show that one spray with 300～400-fold diluted fertilizer or 2 sprays with 400-fold diluted fertilizer in the periods of early flowering and blossm dropping could increase the rate of fruit setting by 1 6%～10 3%, singnificantly increase the size of young fruits, increase the leaf thickness by 0 6%～7 4%, increase the leaf weight per unit area by 2 6%～10 6%,and increase the photosynthetic rate by 39 5%～56 6%.Meanwhile, foliage spray of the fertilizer can also increase single fruit weight ,fruit hardness and soluble solid matters
