【摘要】 叶温是植物重要的生理指标,测量了试验地棉花的叶温,分析了其与当地气象因素的关系。棉花叶温与气象因素的相关性从高到低排列顺序依次为:气温、日照时数、风速、空气相对湿度、空气饱和水汽压差。此外,建立了棉花叶温与气温的拟合方程。该方程的相关系数为0.935 26,拟合效果较好,其拟合方程可以用来预测棉花叶片温度。以便用于指导棉花生产和灌溉,具有很好的实用价值。更多还原

【Abstract】 Leaf temperature is a critical physiological index of plant.In this paper,the cotton leaf temperature of the experimental land is measured and the relation between leaf temperature and local meteorological factors is analyzed.The order of correlation between cotton leaf temperature and local meteorological factors from high to low is air temperature,sunshine duration,air velocity,air relative humidity and air saturated water vapor pressure deficit.In addition,the fitting equation for the relation between cotton leaf temperature and air temperature is established.Its correlation coefficient is 0.935 26.The equation has good fitting result and can be used to forecast the cotton leaf temperature to guide the production and irrigation of cotton crop.So it has good practical value.更多还原
