| Abstract: | Using contractors to test the main technical parameters of the market commonly used ZY-2 impact sprinkler head in layout with 18 m×18 m and in a combination of different meteorological conditions,The results show that the uniformity coefficient of sprinkler irrigation,application efficiency both arrive 0.8 above,sprinkler evaporation and drift loss range from 0.8% to 14.28%,main concentrated in 4% to 10%;Building the regression equation between the main technical parameters of sprinkler irrigation and meteorological factors,work pressure,analyze the most important factor to the application efficiency and sprinkler evaporation and drift loss is the wind velocity,followed by the temperature,relative humidity is the worst.The main factors effected application efficiency are air temperature and wind speed. |
