泾惠渠灌区三原县安乐乡西毛村群众,1985年以来采用间歇灌水法(群众叫改灌)。所谓间歇灌水,就是两个灌水畦用同一流量轮换灌溉,即先灌甲畦,当水流到一定距离时,将水改入乙畦;同样,水流到一定距离又改回甲畦,直至灌到畦尾,再改到乙畦浇灌的一种灌水方法(国外叫涌流灌或波涌灌),由于灌水效率高,质量好,省水省时省投资,深受群众欢迎。三原县安乐乡西毛村属泾惠渠北干分渠14斗管辖,是渠井双灌区。前几年因渠道失修,单靠井水灌溉,又因采补失调,近年来地下水位大幅度下降,造成井水量不足。灌水时,不光是单井,即使两井并流,要灌完一个300m 长畦,往往需用三四个小时, Jinghuiqu Irrigation District Saitama Village, Anle Township, Sanyuan County, since 1985, intermittent irrigation method (the masses called irrigation). The so-called intermittent irrigation, that is, two irrigation 畦 rotation with the same flow of irrigation, that is, the first irrigation armor 当, when the water flow to a certain distance, the water into the B 畦; Similarly, the water flow back to a certain distance and return 甲 畦 until irrigation At the end of the tail, a watering method (such as gushing irrigation or surge irrigation) is applied to water irrigation of B & B. Because of its high irrigation efficiency, good quality and saving water and time and investment, it is well received by the public. Sanyuan County, An Lok township Ximaocun Jing Hui River north of the canal divisions under the jurisdiction of 14 doubles, irrigation wells is double irrigation. A few years ago due to disrepair channels, water alone irrigation, but also due to imbalances in mining, groundwater level dropped significantly in recent years, resulting in insufficient well water. When irrigating, not only is a single well, even if the two wells co-current, to irrigate a 300m long 往 often takes three or four hours,
