| [目的]探讨陕西渭北苹果产区红富士苹果树改形过程中,不同树形的光照分布及其对产量品质的影响,为红富士苹果改良筛选优质树形.[方法]试验以13年生改良的自由纺锤形、小冠疏层形和中干开心形红富士果树为试材,测定了不同树形冠层的光照分布、果实产量和相关品质指标.[结果]自由纺锤形、小冠疏层形和中干开心形3种树形无效光区占整个树冠的比例分别为30.16%,26.54%和24.38%,单株产量分别为34.2,37.5和40.7 kg,其中中干开心形树冠的无效光区最低,其产量较自由纺锤形和小冠疏层形高19.0%和8.5%,且其果实单果质量、果面着色指数、花青苷含量、可溶性固形物含量均高于自由纺锤形和小冠疏层形.[结论]在陕西渭北苹果产区,中干开心形树形冠层光照分布良好,有利于提高果实的品质和产量,果实大、着色好,品质优,优质丰产效果好于自由纺锥形和小冠疏层形,是优质苹果生产优先选择的树形. |

| Abstract: |
| 【Objictive】 This passage discusses the effects of modifying between light distribution and yield and quality of different shapes on "Fuji" apple in the Weibei of Shanxi,to select good quality shape for "Fuji" apple.【Method】 With freed spindle shape,small and sparse canopy shape and open stem and middle center shape as trial trees,these shapes trees are 13-yesrs,and mensures between light distribution and yield and quality of different shapes' canopy for apple wese tested.【Result】 The freed spindle shape,small and sparse canopy shape and open stem and middle center shape's proportion of inefficacy light region were 30.16%,26.54% and 24.38% respectively,and the output were 34.2,37.5 and 40.7 kg of respectively per tree,the inefficacy light region of open stem and middle center shape is low,but the output in open stem and middle center shape is higher than freed spindle shape and small and sparse canopy shape's by 19.0% and 8.5%,and fruit quality,color,anthocyanidinn contents and soluble solids are better than freed spindle shape,small and sparse canopy shape.【Conclusion】 In apple production areas of Weibei of Shaanxi province,the open stem and middle center shape's light distribution is beneficial to improve fruit of quality and yeild,fruit size,good colouring,and quality excellent,good qualityand abundant production better than freed spindle shape,small and sparse canopy shape.So open stem and middle center shape is priorior selection of tree shape high quality apples production. |
