1973年秋,我们在河北省曲周县建立了一个耕地面积6,000亩的旱涝碱成综合治理试验区。试区属黄淮海平原黑龙港流域,春早少雨,地上水缺乏,井灌面积只有7%;由于地势低洼,排水不良,百十毫米降雨就受涝成灾;盐碱土(主要是 SO_4—Cl 型)占总面积的83%;浅层地下水均为矿化度在7克/升左右的咸水。在旱涝碱咸的严重危害下,产量低而不稳,群众吃粮靠国家,花钱靠救济。四年多来,在省地县各级党委领导下,在根治海河工程的基础上,采取以浅机井和深沟为主的“井组沟网结合,农林水并举”的综合治理旱涝碱咸的方法,已取得初步成果,产量有了较大幅度提高。治理前,张庄大队历史最高亩产264斤,总产30万斤,治理的第
In the autumn of 1973, we established a 6,000-acre droughst and alkali into a comprehensive pilot area in Quzhou County, Hebei Province. The test area belongs to the Heilonggang valley of the Huang-Huai-Hai Plain, where rainfall is scarce in the early spring and lacks in groundwater. The well irrigation area is only 7%. Due to the low lying and poor drainage, the precipitation of one hundred and ten millimeters is affected by flooding. Saline-alkaline soil (mainly SO 4 -Cl ) Accounted for 83% of the total area; shallow groundwater salinity of salinity of about 7 g / l. Under the serious damage caused by drought, flood and salina, the output is low and unstable, and the masses eat food by the country and spend money on relief. In the past four years or so, under the leadership of party committees at all levels and under the leadership of the provincial and county governments, and based on the Haihe River project, we have taken the comprehensive control of Drought and Waterlogging Salinity The initial results have been achieved and the output has been greatly improved. Before the management, Zhang Zhuang Brigade, the highest yield 264 pounds, a total output of 300,000 catties, the governance of the first
