喷洒水滴的大小是衡量喷灌质量的重要指标,同时也是喷灌设备运用经济合理性的反映。因为,从一般常识来说,水滴越小,对土壤和作物的影响越小,但是对目前常用的旋转式喷头来说就意味着能源消耗越大,况且,水滴越小蒸发损失越大。当然大水滴又由于具有较大的动能,容易造成土壤入渗 The size of sprayed water droplets is an important indicator of the quality of sprinkler irrigation, but also reflects the economic rationality of sprinkler irrigation equipment. Because, from the common sense, the smaller the water droplets, the smaller the impact on the soil and crops, but for the current spin-on jets means that the greater the energy consumption, Moreover, the smaller the smaller the evaporation loss. Of course, due to large water droplets have greater kinetic energy, easily lead to soil infiltration
