| 摘 要： | 采用不同方法模拟冬小麦缺水状况，测定冠层温度日变化过程及不同处理叶面温度变化的结果表明，水分亏缺使冠层温度升高1.5～2.0℃。长期干旱使作物生长不良，冠层温度对土壤水分亏缺敏感程度下降。

| Abstract: | Experiments to simulate effects of water deficiency on winter wheat were conduct ed and the diurnal changes of canopy temperature under different water content t reatments were observed.Water deficiency could induce canopy temperature to incr ease about 1.5～2.0℃.Crops grew poorly under long period of drought,and the sens itivity of canopy temperature to water deficiency decreased. |

| Keywords: | Canopy temperature Water deficiency |
