入渗水矿化度对点源滴灌土壤水盐运移特征的影响
Effects of Water Salinty on Soil Salt and Water Movement under a Point Source Drip Irrigation
摘要
Abstract
This paper studies initially on salt and water movement affected by mineralization degree of infil-tration water under a buried trickle source through laboratory test. The results show that, at the same depth of soil,the higher the salinity of water,the greater for soil moisture and soil salinity profiles. At the same infiltration time,the higher the salinity of water,the greater for the migration distance of moist in the horizontal direction; Under point sources drip irrigation, the distance of wetting front transport is related drip time with a nonlinear correlation.关键词
