文章对不同工作条件下喷灌系统的蒸发及漂移损失量的确定进行了研究,试验是在Nebraska大学设于Nead东南的大田试验场燕麦荏地上进行。在该试验条件下,用电导率方法确定的蒸发损失范围为喷洒总量的1.5～16.8％。风速和水汽压差是影响蒸发损失最重要的因素,探明蒸发损失与风速和水汽压差之间是一种指数关系。(其他影响
In this paper, the evaporation and drift loss of irrigation and sprinkler irrigation system under different working conditions were studied. The experiment was conducted on the oatmeal land of the University of Nebraska at the field test field in the southeast of Nead. Under this test condition, the evaporation loss, as determined by the conductivity method, ranges from 1.5 to 16.8% of the total spray volume. Wind speed and water vapor pressure difference are the most important factors affecting evaporation loss. It is an exponential relationship between evaporation loss and wind speed and water vapor pressure difference. (Other effects
