从1980-1982年,我们在孔集公社旱涝碱综合治理实验区,对土壤盐分高,改造难度大,以钠镁为主的氯化物盐土(群众叫万年湿)进行淋盐种稻试验和示范,特别是雨季种稻,对改良“万年湿”盐土取得了显著的效果.孔集公社位于宁陵县东北,黄河古堤南侧背河洼地,土壤母质为石灰性黄泛沉积物.全社有盐碱耕地18080亩,占总耕地55.3%,另有盐碱荒地7740亩.盐碱类型主要有臭碱(苏打盐化潮土)、盐碱(硫酸盐氯化物盐化潮土)和瓦碱(表层碱化潮土),各种类型和轻重不同的盐渍土呈云状复区分
From 1980 to 1982, we experimented in the comprehensive management of droughts and alkalis in Kongji Commune to test the effects of high salinity, transformation difficulty and sodium chloride-based chloride salt soil (the masses called wet years) And demonstration, especially the rice planting in rainy season, has achieved remarkable results in improving the “wet years” of saline soil.Kongji Commune is located in the northeast of Ningling County, the back river depression in the south of the Yellow River ancient embankment, and the soil parent material is yellowish yellowstone Sediment. The whole community has 18,080 acres of saline-alkali soil, accounting for 55.3% of the total arable land, and another 7,740 acres of saline-alkali wasteland. Saline types are mainly soda (soda saline), saline (saline salt chloride tide Soil) and tile base (surface alkalized alluvial soil), different types and severity of salty soil cloud complex subdivision
