喷灌灌水过程中,水滴在空气中要蒸发一部分水量(应指出,喷灌水滴蒸发损失主要是喷水所形成小雾滴不能降落到地面而飞散所造成的,原文作者全归之为蒸发不恰当。),损失量受空气相对湿度和风力的影响,因地不同,也因不同机型的射程不同而有差异。因此,在灌水定额的设计中应把这个损失水量附加进去,也就是说灌水定额也有个有效利用系数问题。目前这方面的资料尚少,特将本文节译供参考。
Sprinkler irrigation process, water droplets in the air to evaporate part of the amount of water (it should be noted that the loss of spray water droplets evaporation is mainly caused by the formation of small drops of water can not fall to the ground and caused by the scattering, the original author of the evaporation as inappropriate. ). The amount of loss is affected by the relative humidity of the air and the wind force. Due to different locations, the amount of loss varies depending on the range of different models. Therefore, in the design of irrigation quota should be added to the loss of water, which means that irrigation quota also has an effective utilization factor. At present, there is still little information in this regard, especially the section translated for reference.
