河南省镇平县南部井灌区共有九个乡(镇)35.5万人。总耕地50.6万亩,其中宜井面积44万亩。灌区地势平坦,土质肥沃,是该县粮棉油集中产区。自1964年以来累计打井4700眼,配套4100眼,效益面积曾达24.6万亩,在发展农业生产中发挥了巨大作用。但由于原来配套标准低,又经过多年运行,设备老化,工程失修,效盖面积严重衰减,到1985年底,配套机井只剩下2 598眼,效益面积减为14.5万亩。 1986年,镇平县被确定为粮食基地建设重点县,在制订总体规划时,该县把南部井灌区建设列为一项重点工程。县政府成立以主管县长、农经委主任,水利局长等主要领导

Since 1964, a total of 4,700 wells have been drilled, 4100 have been matched and the benefit area has reached 246,000 mu, which has played a significant role in the development of agricultural production. However, due to the low standard of supporting facilities and years of operation, equipment aging, project disruption and serious decay of effective cover area were completed. By the end of 1985, there were only 2 598 eyes of supporting machine wells, reducing the benefit area to 145,000 mu. In 1986, Zhenping County was identified as the key county in the construction of the grain base.
