选用北方地区简易日光温室及大棚内生长的常见蔬菜黄瓜为试验材料,建立植物的叶片温度生理信息模型。研究了环境温度对叶片温度一天内的变化规律,分析了叶片温度的生理适应性机理,并进行环境温度与叶片温度拟合,决定系数R2=0.9128;阐述了叶片水分利用效率对于叶片温度的影响,并建立了基于叶片水分利用效率修正下的叶片温度模型,其模型的决定系数达到R2=0.9360,经检验,模型具有较高的精确度。
The simple greenhouse and the common vegetable cucumber grown in the greenhouse were selected as the experimental materials to establish the plant leaf temperature physiological information model. The change rule of the temperature on the leaf temperature was studied in one day. The physiological adaptability mechanism of the leaf temperature was analyzed, and the temperature was fitted to the leaf temperature to determine the coefficient R2 = 0.9128. The effect of leaf water use efficiency on leaf temperature , And established a blade temperature model based on leaf water use efficiency amendment, the determination coefficient of the model reached R2 = 0.9360, after testing, the model has a higher accuracy.
