山西翼城县利民渠灌区在去年以0.7个流量灌溉农田73,000亩,平均一个流量10万亩,今年计划在这个基础上,进一步大挖水源潜力,加强渠系防渗,使滴水归田,再扩大灌溉面积25,000亩。平均一个流量保浇14万亩,誓夺全专冠军。这个灌区有清水0.7秒立方米,全年出水量2,207万立方米,按渠系利用率85％计算,实用水量可达到1,867万立米,以麦田5万亩浇水四次,灌溉定额160立方米,棉田48,000亩浇水三次,灌溉定额120立方米,夏播5万亩浇水三,每亩灌溉用水90立方米计算,共需水量1,826万立方米,尚余50余万立方米水,以济有无,以补不足,全年可保证98,000亩的土地适时用水。其具体办法是:
Last year, the Limin Canal Irrigation District in Yicheng County, Shaanxi Province, irrigated 73,000 mu of farmland with an average flow rate of 100,000 mu at a flow rate of 0.7. Based on this plan, this year plans to further tap the potential of water resources and enhance the seepage control of the canal so that the drip water can be returned to the field. Expand irrigation area of 25,000 mu. An average of a flow Paul pouring 14 acres, vowing full championship. The irrigation area has 0.7 seconds of clean water and 20.27 million cubic meters of water per year. According to the utilization rate of 85% of the canal, the actual water volume can reach 18.67 million cubic meters and the watering of 50000 acres of wheat fields is carried out four times. The irrigation quota is 160 cubic meters , 48,000 acres of cotton watering three times, irrigation quota 120 cubic meters, summer sowing 50000 acres of water three, 90 cubic meters per acre of irrigation water, a total of 18260000 cubic meters of water, there are more than 500000 cubic meters of water to Whether or not there is enough money to make up for the deficiencies, 98,000 mu of land can be guaranteed timely water supply throughout the year. The specific method is:
