摘要
芒果花期高温对授粉受精影响特别大,2020年3月攀枝花晚熟芒果花期遭受10年来高温,最高气温达到37.4℃,给攀枝花的芒果产量造成相当程度的减产。通过对四川省攀枝花市2020年芒果花期气象要素资料、气候特点进行统计分析,结合芒果的生物学特性、物候发育期及农业气象灾害指标,着重分析攀枝花市仁和区、盐边县、米易县3个国家气象站2020年2、3月的基础气象资料(温度、湿度),并与2010—2019年同期进行对比得出2020年3月最高气温升温趋势明显,相对湿度下降趋势明显,3月中旬和下旬形成严重的干热风,探讨此次芒果花期高温天气(干热风)对攀枝花市芒果生产的影响,并提出相应的生产防御对策,以达到趋利避害。
The high temperature during the flowering period of mangoes has a particularly great impact on pollination and fertilization.In March 2020,Panzhihua’s late-ripening mangoes suffered a 10-year high temperature during the flowering period,with the highest temperature reaching 37.4℃,which caused a considerable reduction in Panzhihua’s mango production.Through statistical analysis of meteorological element data and climatic characteristics of mango flowering period in Panzhihua City of Sichuan Province in 2020,combining mango biological characteristics,phenological development period and agricultural meteorological disaster indicators,this paper focused on the basic meteorological data(temperature,humidity)of the three national weather stations(Renhe District,Yanbian and Miyi County in Panzhihua City)in February and March 2020.Meanwhile,the result was compared with the same period data from 2010 to 2019,it was found that the maximum temperature in March 2020 increased significantly,the relative humidity decreased significantly,and severe dry and hot winds were formed in the middle and late periods in March.The impact of the high temperature weather(hot and dry wind)during the flowering period of the mangoes on the mango production in Panzhihua was discussed,and corresponding production defense countermeasures were proposed to achieve benefits and avoid disadvantages.
