ZY-2摇臂式喷头组合喷灌技术参数田间试验研究

A Study on the Main Technical Parameters of ZY-2 Impact Drive Sprinkler Head

采用承雨筒测量法,对目前市场上常用的ZY-2摇臂式喷头采用18 m×18 m布置方式在不同气象条件下的组合喷灌主要技术参数开展田间试验研究。结果表明,组合喷灌均匀系数、喷洒水利用系数均在0.8以上,蒸发漂移损失的测试值为0.8%~14.28%,主要集中在4%~10%。构建了组合喷灌主要技术参数与主要气象因素、工作压力的回归模型,分析得出影响喷洒水利用系数、蒸发漂移损失的最主要因素是风速,其次是温度,相对湿度的影响最小。影响组合喷灌均匀系数的主要因素依次为空气温度和风速。

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.
