摘　　要：利用湖北省孝昌县丰山镇桃(Amygdalus persica Linn.)品种孝昌血桃品质数据和同期气象资料,基于文献研究和实地调查分析了关键期气象因子对品质的综合贡献以及气候品质与果实品质之间的关系,构建了孝昌血桃气候品质评价模型,并对模型进行了验证和区划应用。结果表明,果实迅速膨大期至成熟期是孝昌血桃品质形成的关键期,该时段的温度、光照、降水和湿度是影响其品质的主要气候因子;气候品质指标为果实膨大期前3候的平均气温、气温累计日较差、日照时数以及果实成熟期前3候的日照时数、降水量、相对湿度;模型计算的气候品质指数与果实综合品质指数高度相关,相关系数为0.944;模型对主产区2011—2022年的孝昌血桃气候品质评价结果中,有11年与果实综合品质等级基本相符,比例高达90%以上;应用模型对孝昌县近5年的孝昌血桃气候品质等级区划结果中,有4年气候品质为“优”和“特优”的面积超过了85%。Using the quality data of peach(Amygdalus persica Linn.)variety“Xiaochang Xue Peach”from Fengshan Town,Xiaochang County,Hubei Province,and the meteorological data in the same period,the comprehensive contribution of meteorological factors to quality in the critical period and the relationship between climatic quality and fruit quality were analyzed based on literature research and field investigation,the climatic quality evaluation model of“Xiaochang Xue Peach”was constructed,and the model was verified and applied in regionalization.The results showed that the key period of quality formation of“Xiaochang Xue Peach”was from fruit rapid expansion to fruit maturity,and the temperature,light,precipitation and humidity during this period were the main climatic factors affecting its quality.The climate quality indexes were the average temperature,cumulative daily temperature range,sunshine hours in the first three periods of fruit rapid expansion,and the sunshine hours,precipitation and average relative humidity in the first three periods of fruit maturity period.The climate quality index calculated by the model was highly correlated with the fruit comprehensive quality index,and the correlation coefficient was 0.944.The climate quality evaluation results of“Xiaochang Xue Peach”in the main production area from 2011 to 2022 by the model were basically consistent with the comprehensive quality grade of fruits in 11 years,with a proportion of more than 90%.In the division results of the climate quality grade of“Xiaochang Xue Peach”in Xiaochang County in recent 5 years using the model,the area with“excellent”and“super excellent”climate quality in 4 years exceeded 85%.
