矮化富士苹果树冠不同部位果实品质分析

Analysis of Fruit Quality of Different Parts of Dwarf Fuji Apple Crown

以矮化富士苹果树为试材,采集不同树冠方位果实,对品质进行测定及分析。研究了苹果矮化栽培模式对不同树冠方位果实品质的影响。以期明确矮化苹果不同树冠方位果实品质性状差异,为进一步改造老果园及优化树体结构提供参考依据。结果表明:外在及内在品质中上部优于下部,东南部优于西北部;大量及微量元素中下部优于上部,水平方向无明显规律。

Dwarf Fuji apple tree was taken as the test material, fruits of different crowns were collected and the quality was tested and analyzed. The influence of dwarf apple cultivation mode on the quality of fruits of different crowns was studied to clarify the difference in the quality of dwarf apples with crowns at different positions to provide scientific basis for further transformation of old orchard and the optimization of tree structure. The results showed that the external and internal quality of the middle and upper part were superior to that of the lower part, and the quality of the southeast was better than that of the northwest; massive and microelements at the middle and upper part were superior to that at the upper part without obvious laws in the horizontal direction.
