摘　　要：作物冠层温度是作物遗传特性和环境条件共同作用的结果,它不仅影响叶片的功能期、蒸腾速率和光合能力,也影响籽粒蛋白质含量和淀粉合成。作物花后特别是灌浆中后期的冠层温度对产量具有较大影响。本文概述了冠层温度对作物产量的影响机理和影响因素的研究进展,并指出优良基因型的选育和合理的栽培管理措施是降低冠层温度、提高产量的有效途径。Crop canopy temperature is the outcome of the interactions of crop＇ s genetic characteristics and environmental conditions, which not only affects leaf functional period, transpiration rate, and photosynthetic capacity, but also affects grain protein content and starch synthesis. Crop yield is strongly affected by the canopy temperature after flowering, especially at mid-late grain-filling stage. This paper reviewed the research advances on the effects of canopy temperature on crop yield, related mechanisms, and the factors affecting canopy temperature, and pointed out that to breed superior genotypes and to implement reasonable agronomic practices should be the effective ways for improving crop yields and reducing canopy temperature.
