盘锦滨海盐渍土区位于辽宁省的西南部:南临渤海湾,东起辽河下游西岸,西至锦县小凌河,北抵沈山线沟邦子镇附近,面积约1,800平方公里,区内地势低平,地面高程在海拔2～5米间,土质粘重,地下水位高且矿化度大,分布有轻重不同的盐渍化土壤。这些土壤中含有多量易溶性盐类,严重地影响了 作物的生长。种稻改良盐渍土是当地群众与盐渍化作斗争的有效措施之一。种稻必须借助于开沟排水,才能达到彻底洗盐的目的,但由于此区地势低平,排水
Panjin Binhai saline soil area is located in the southwest of Liaoning Province: Bohai Bay to the south, east of the Liaohe River in the west from west, west Xiaoxinghe Jinxian, north of Shen Shan line ditch Bangzi town, an area of about 1,800 square kilometers, the area Low terrain, the ground elevation of 2 to 5 meters above sea level, soil sticky, high groundwater level and salinity, distributed in different salinity of the soil. These soils contain large amounts of readily soluble salts that severely affect the crop’s growth. Planting rice to improve saline soil is one of the effective measures for local people to combat salinization. Rice must be dredged drainage, in order to achieve the purpose of a thorough wash salt, but because of the low level of the area, drainage
