2025年黑龙江夏季高温特征及其对春玉米生长的影响
Characteristics of summer high temperatures in Heilongjiang in 2025 and their impact on the growth of spring corn
摘要
Abstract
To analyze the impact of high temperatures in Heilongjiang in 2025 on agriculture,this study introduces the critical threshold of daily maximum temperature tmax≥35℃ to identify high temperatures based on the daily temperature data of ground meteorological observing stations in Heilongjiang between June and August from 1981 to 2025.Methods such as Pearson correlation analysis are used to analyze the frequency,concentrated periods,the number of days,spatial-temporal distribution characteristics and evolution laws of high temperatures.The study reveals the impact of high temperatures on the growth and development of spring corn.The results are shown below.(1)The extreme high-temperature weather processes in the study area in the summer of 2025 are divided into three periods,and the number of high-temperature days is 4 d more than normal years.(2)The spatial variation of daily average maximum temperature in the summer of 2025 features a distribution pattern of lower in the north and higher in the south,and the number of high-temperature days shows a trend of gradually increasing from the central part to the north and south.The temperature is close to abnormally warm only in July,and the stations are mainly distributed in the southeast of Heilongjiang,overlapped with the area where the growth stage of spring corn is shortened.(3)The number of days in the growth stage presents a trend of decreasing with the increase in the maximum temperature,which to some extent indicates that high temperatures promote the growth of spring corn.The overall meteorological conditions in 2025 are relatively favorable for the growth and development of spring corn.关键词
