在毛主席革命路线指引下,东方红灌区灌溉面积已经发展到128.6万余亩。几年来,在抗旱夺丰收的斗争中发挥了巨大的作用。粮棉产量不断提高,支援了国家社会主义革命和建设。但随着灌溉面积的扩大和农业生产水平的提高,水的供需矛盾日益突出。夏灌缺水达一亿七千余万立米,全年缺水二亿立米以上。为了解决这一矛盾,除加强灌溉管理工作外,必须充分利用本灌区的地下水。为此,我们曾经对本灌区地下水作了普查。按地下水含盐量的多少分成四级。矿化度小于1.7克/升的面积有四十七万二千九百余亩,占全灌区面积百分之三十六点八;矿化度1.7克/升至2.9克/升的面积有三十三万三千七百余亩,占全灌区面积百分之二十六点零;矿化度3克/升至5克/升面积有二十二万
Guided by Chairman Mao’s revolutionary line, irrigated area in the Dongfanghong Irrigation Area has grown to more than 1,286,000 acres. In recent years, it has played a huge role in the fight against drought and harvesting. The output of grain and cotton has been continuously increased, supporting the national socialist revolution and construction. However, with the expansion of irrigation area and the improvement of agricultural production, the contradiction between supply and demand of water has become increasingly prominent. Summer irrigation shortage of more than 170 million cubic meters, more than 200 million cubic meters of water throughout the year. In order to resolve this contradiction, we must make full use of the underground water in this irrigation area besides strengthening irrigation management. For this reason, we conducted a general survey of the groundwater in this irrigation district. According to the amount of groundwater salinity divided into four. The area of salinity less than 1.7g / L is 472,900mu, accounting for 36.8% of the total irrigated area. The salinity ranges from 1.7g / l to 2.9g / l 333,700 acres, accounting for 26.0% of the entire irrigation area; salinity 3 g / l to 5 g / l, with an area of 220,000
