To improve the high temperature resistance of citrus in Wusheng County, Sichuan Province and promote high and stable yield of the citrus industry, this study took Daya citrus as the research object, selected the temperature observation data from 2016 to 2024 and the statistical data at the same time of high temperature days from meteorological stations, and focused on analyzing the variation characteristics of the maximum temperature and high temperature days during the growth period of Daya citrus. The results showed that from 2016 to 2024, the maximum temperature during the flowering period and fruit expansion period of Daya citrus in the study area showed an increasing trend to varying degrees, with the change rates of 2.867 ℃/10 a and 0.683 ℃/10 a respectively, and the maximum temperature during the flowering period increased more obviously. High temperature weather occurred to varying degrees during both the flowering period and fruit expansion period of Daya citrus, with the highest frequency of high temperature in the fruit expansion period (297 days) and relatively fewer in the flowering period (18 days). Therefore, targeted and precise prevention and control technical measures were proposed from the dimensions of constructing a refined agricultural meteorological monitoring and early warning system, carrying out artificial precipitation enhancement operations in a timely manner, and establishing a multi-departmental linked prevention and control system, so as to provide a reference for the stable and high quality production of local Daya citrus and the scientific response to high temperature disasters.
