摘要
对毛乌素沙地喷灌条件下蒸发漂移损失进行了试验研究,经数据分析,得出风速和空气相对湿度是影响当地灌水损失的重要因素,当风速<3 m/s时,喷灌水的利用率可达80%以上,此气象条件下适宜进行灌溉。
Based on the tentatively study on vaporing- drift loss of spray irrigation in Maowusu sandlot, we draw a conclusion that wind speed and the relative humidity of air are the important factors to influnce loss of spray irrigation in there. The utilization of water can be above 80% when wind speed is less than 3 m/s, it is feasible to irrigate under this weather condition.
