| 中文摘要: |
| 马家柚是我国柑橘地方良种，但品质易受环境影响。为进一步明确气象因子对马家柚品质的影响，本研究测定并分析了2013-2023年的气象数据和马家柚品质数据，为下一步通过栽培措施或者设施条件等技术提升马家柚品质提供依据。结果表明：①8月至11月中旬的气象条件对马家柚影响最大，其9月是最关键月份。②有效积温高，日较差大，日照时数多，有利于提升马家柚品质，而降水量多会显著降低马家柚品质。③根据综合评比，正常管理条件下，有利于马家柚达到可溶性固形物为10 %以上的气象指标：8月-11月中旬的有效积温1545.9 ℃以上，日较差9.5 ℃以上，日照时数616.3 h以上，降水量163.1mm以下。④关键月份9月的气象指标为有效积温481.1℃以上，日较差8.9 ℃以上，日照时数累计180.5 h以上，降水量小于97.6 mm以下。 |
| 英文摘要: |
| The Majiayou pomelo is a local superior variety of citrus in China, the fruit quality of Majiayou pomelo is easily affected by environmental factors. To further clarify the impact of meteorological factors on the quality of Majiayou pomelos, this study measured and analyzed the meteorological data and quality data of Majiayou pomelos from 2013 to 2023, aiming to provide a basis for improving the quality of Majiayou pomelos through cultivation measures or facility conditions and other techniques in next steps. The results are as follows: firstly, the meteorological conditions from August to mid-November have the greatest impact on Majiayou pomelos, and September is the most critical month; secondly, high effective accumulated temperature, large diurnal temperature range, and long sunshine duration are conducive to improving the quality of Majiayou pomelos, while excessive precipitation will significantly reduce the quality of Majiayou pomelos; thirdly, according to the comprehensive evaluation, under normal management conditions, the meteorological indicators conducive to the Majiayou pomelo reaching a soluble solid content of more than 10% are as follows: the effective accumulated temperature from August to mid-November is above 1545.9 °C, the diurnal temperature range is above 9.5 °C, the sunshine duration is above 616.3 h, and the precipitation is below 163.1 mm; fourth, the meteorological indicators for the critical month of September are as follows: the effective accumulated temperature is above 481.1 °C, the diurnal temperature range is above 8.9 °C, the cumulative sunshine duration is above 180.5 h, and the precipitation is below 97.6 mm. |
