摘要:

为探究河北省南部核桃冠层温度与大气温度的关系,本研究以河北南部沙河市康源核桃基地为研究对象,监测不同海拔核桃关键生育期冠层温度变化特征,并运用统计分析方法对冠层温度与大气温度数据进行回归分析。研究结果表明,不同海拔的冠层温度与大气温度均呈高度正相关,其相关系数为0.91~0.98,决定系数均大于0.75;当大气温度为35~39℃时,大气温度与核桃冠层最高温度差异较小,而当大气温度高于40℃时,冠层温度最高可高于大气温度2.8℃;冠层最低气温受海拔影响最为敏感,低温时段为4:00—6:30,核桃冠层最低温出现时间日期比大气温度出现时间滞后,冠层最低气温低于大气温度2.7℃左右。本研究可为农业气象服务中核桃低温冻害和高温日灼的风险预警提供科学依据。

Abstract:

To explore the relationship between canopy temperature of walnut and atmospheric temperature in southern Hebei province, this study took Kangyuan Walnut base in Shahe City, southern Hebei Province as the research object, monitored the characteristics of canopy temperature changes in key growth stages of walnut at different altitudes, and used statistical analysis methods to conduct regression analysis on the data of canopy temperature and atmospheric temperature. The results indicated that the canopy temperature at different altitudes was highly positively correlated with the atmospheric temperature, with correlation coefficients ranging from 0.91 to 0.98 and coefficients of determination all exceeding 0.75, showing high positive correlation. When the atmospheric temperature is 35-39℃, there is little difference between the atmospheric temperature and the maximum canopy temperature of walnut. When the atmospheric temperature is higher than 40℃, the maximum canopy temperature is 2.8℃ higher than the atmospheric temperature. The minimum temperature of the canopy is most sensitive to the influence of altitude, and the low temperature period is from 4:00 to 6:30. The time and date of the minimum temperature of the walnut canopy are lagging behind that of the atmospheric temperature, and the minimum temperature is about 2.7℃ lower than the atmospheric temperature. The research will provide scientific support for the early warning of low temperature freezing damage and high temperature sunburn risk in agricultural meteorological service.
