赵紫阳总理视察我省工作时指出:“搞灌溉农业,必须十分注意节约用水。到底采用什么灌溉方法,大水漫灌,既浪费水量,效果也不好,搞得不好,还盐碱化”。指示切中灌溉农业的要害问题。我省大部分地区降雨偏少,永资源比较缺乏,农业生产受干旱威胁较大,灌溉增产效益显著。据1950～1979年统计资料分析,全省已成灌区粮田面积累计为23500万亩,总产1200亿斤,棉田面积累计为4700多万亩,总产棉花2780万担。按同期旱地产量水平扣除后,三十年来水地净增产粮食770亿斤,棉花1160万担。按每斤粮食0.15元,每斤棉花1.5元
During his visit to our province, Zhao Ziyang pointed out: "In irrigating agriculture, we must pay great attention to saving water. In the end, what irrigation methods are used to flood large amounts of water is not only a waste of water but also ineffective and badly salinized. . Indicate the key issue of cutting irrigation agriculture. Rainfall in most parts of our province is less than normal, the lack of permanent resources, the greater threat to agricultural production by drought, irrigation yield significantly. According to statistical data from 1950 to 1979, the province has become irrigated area has accumulated 235 million mu of grain, with a total output of 120000000000 jin, an area of cotton totaling more than 4700 mu, 27.8 million total cotton production. After deducting the output level of dry land in the same period, the net increase of output of grain in the past 30 years was 77.0 billion kg and 11.6 million tons of cotton. 0.15 yuan per kilogram of grain, 1.5 yuan per catty of cotton
