淮阴专区有碱地244万余亩,约占总耕地面积的12.8%,且有扩展趋势,严重影响着棉产量的跃进。因之我所于1957年进行花碱地植棉技术研究。该地土壤疏松,系盐渍化浅色草甸土,地面较平,排水尚好,地下水位在1米以下,有机质含量0.4—0.7,酸碱度7.8—8.2,表土层全量0.035—0.061%,盐份(氯化钠)含量0.05—1.06%。经过两年培育,均获得丰产,1957年1.2亩单产籽棉391斤,比隣地机场公社繁荣大队同类型碱地籽棉单产
There are more than 2.44 million mu of alkali in Huaiyin area, accounting for 12.8% of the total cultivated area, and there is an expansion trend that seriously affects the leap in cotton production. Because of my plant in 1957 Huaian cotton technology research. The soil is loose, salinized light-colored meadow soil, the ground is relatively flat and the drainage is still good. The groundwater level is below 1m, the organic matter content is 0.4-0.7, the pH value is 7.8-8.2, the topsoil is 0.035-0.061% (Sodium chloride) content of 0.05-1.06%. After two years of cultivation, have received high yield, 1957 1.2 acres of seed cotton yield 391 pounds, adjacent to the airport commune prosperity brigade of the same type of alkali seed cotton yield
