| 中文摘要: |
| 本研究以巨峰葡萄为研究对象，探索在高海拔山区运用不同断根方式对旺树枝叶生长及物候期的影响。结果表明：不同断根处理较对照组（未断根），其物候期、生长势、果实品质均有显著差异。其中离植株40 cm处挖30 cm宽环状沟，沟深40 cm处理，萌芽期推迟16 d、新梢粗度下降39.4 %、叶面积下降66.5 %、小果率下降47.5 %，显著低于对照；可溶性固形物提升至21.9 %，花色苷提升1.2 %，总糖提升至122.2 mg/ml，显著高于对照。断根处理可有效推迟物候期，削弱地上部生长，提高果实品质。本试验结果可为高海拔山区种植的巨峰葡萄在控制长势，推迟物候期以及提高果实品质提供理论依据。 |

| This study took Kyoho grape（Vitis vinifera）as the research object, and explored the influence of different root cutting methods on the growth and phenological period of vigorous branches in high-altitude mountainous areas. The results showed that: compared with the control group (non-cutting roots), different root cutting treatments had significant differences in phenology, growth vigor, and fruit quality. Among them, a 30 cm wide ring trench was dug 40 cm away from the plant and the trench depth was 40 cm. The germination period was delayed by 16 days, the shoot thickness decreased by 39.4%, the leaf area decreased by 66.5%, and the small fruit rate decreased by 47.5%, which was significantly lower than Control; soluble solids increased to 21.9%, anthocyanins increased by 1.2%, total sugar increased to 122.2 mg/ml, significantly higher than the control. Root cutting can effectively delay the phenological period, weaken the growth of the above-ground part, and improve the quality of the fruit. The results of this experiment can provide a theoretical basis for controlling the growth of Kyoho grapes grown in high-altitude mountainous areas, delaying the phenological period and improving fruit quality. |
