| 英文摘要 | A field experiment was carried out to investigate the effect of sprinkler irrigation on field microclimate under dry-hot wind condition during later winter wheat growing period in the North China Plain. Results indicated that canopy temperature decreased sharply after sprinkling. Past 50 - 60 minutes, canopy temperature came back and was near to that in the field without sprinkling. Water surface evaporation (E-20(20)), as an "integrator" of the change of filed microclimate measured using standard 0.2m diameter pan installed on the top of canopy, was lower than that in the field without sprinkling about 0.8mm. A model was developed to describe the relationships of the change of canopy temperature and air temperature, relative humidity and wind speed. It was found that the estimated value of canopy temperature using the model was well fit to the measured value in 2002. Another model was also developed to express the relationships of the change of E to sprinkler water amount, air temperature, relative humidity and wind speed. Winter wheat yield in the field with sprinkler was higher than that in the field without sprinkler about 291 kg/ha. In general, sprinkling a small amount of water (about 1.0 - 1.5mm for one time) is a useful method to regulate field microclimate, decreasing the canopy temperature and field evaporation potential, under dry-hot wind condition. |
