摘　　要：本文对白城市水稻种植区灌溉用水的物理和化学特征进行了系统研究。结果表明 :白城市水稻种植区的灌溉用水水源可以分为地表自流灌溉水、浅井灌溉水、深井灌溉水三种 ;不同水源的灌溉用水水质存在一定差异 ;灌溉用水的水质成分与土壤的元素组成存在着一定关系 ,且影响水稻的产量。The article systemically studies the physical and chemical characteristics of the irrigated water in Baicheng paddy planting area indicates that the irrigated water in the paddy planting areas can be divided into three types (1.surface water 2.shallow water 3.deep-well water). There are some differences in different types of irrigated water in physical and chemical properties, and the chemical components of irrigated water have the relation with the elements of soil; the paddy yield is influenced by the physical and chemical characteristics of irrigated water.
