利用2016—2025年锦屏县国家气象站的气温、降水、日照等气象数据，从气候角度上对锦屏县蜂糖李花期坐果率进行分析，采用数理统计等方法，系统分析气象因子与坐果表现的相关性。结果表明：锦屏县高温年份（2021年、2023年、2025年）花期日平均温度> 14℃，雨日<6 d，坐果率> 35%；低温阴雨年份（2018年、2022年）日平均温度<12.5℃,雨日>10 d，日照<20 h，坐果率<20%。出现连续降水、寡日照等天气，会进一步降低授粉率。锦屏县蜂糖李花期气象因子对坐果率的影响强度排序：日平均温度>日照时数>相对湿度>阴雨日数>风速。

Based on meteorological data including temperature, precipitation and sunshine duration from Jinping National Meteorological Station during 2016–2025, this paper analyzes the fruit setting rate of 'Fengtangli' Plum during flowering period from a climatic perspective. Using mathematical statistics and other methods, the correlation between meteorological factors and fruit setting performance was systematically analyzed. The results showed that in high-temperature years(2021, 2023, 2025) in Jinping County, the average daily temperature during flowering was >14 ℃, rainy days <6 d, and fruit setting rate >35%; in low-temperature and rainy years(2018, 2022), the average daily temperature <12.5 ℃, rainy days >10 d, sunshine duration <20 h, and fruit setting rate <20%. Continuous precipitation and less sunshine further reduced the pollination rate. The order of influence intensity of meteorological factors on fruit setting rate of 'Fengtangli' plum during flowering period in Jinping County was: average daily temperature > sunshine duration > relative humidity > rainy days > wind speed.
