吉林省西部低洼易涝盐碱化耕地的分类管理技术研究

Systematic Techniques for soil management in Low land and Waterlogging regions

吉林省西部的盐碱涝洼耕地，多属于盐化或碱化土壤，本 文指其盐渍化及涝害程度划分为重度碱化涝洼弃耕地、中度碱化易涝耕地、轻度碱化易涝耕 地及盐碱集中分布的涝洼耕地群等４类，因地制宜地实施分类的技术管理，获得良好的效果 ，增产增收，土壤肥力逐步提高．

Because of low land and waterlogging,the main soils in the western Jilin are either Salinized or alkalinized or both with different degrees.We therefore classified the soils four types according to their properties.In this context,differ- ent measures and approaches could be used to manage the soils in o lder to increase productivity and improve soil fertility.
