不同灌溉蒸发比对土壤水盐分布的影响分析
Different Irrigation Evaporation Ratios on Soil Water and Salt Distribution
摘要
Abstract
Investigating the influence of environmental factors on soil water and salt transport is crucial for the scientific improvement and efficient utilization of saline-alkali land.This study used numerical calculations to explore the effects of different irrigation-evaporation ratios and groundwater salinity on soil water and salt transport.The results showed that:different irrigation-evaporation ratio treatments had little effect on deep soil moisture content;the smaller the irrigation-evaporation ratio and the higher the groundwater salinity,the more significant the accumulation of salt in the soil profile.When the groundwater salinity increased from 1 g/L to 10 g/L,the maximum salt content increased from 12.20 g/kg to 67.60 g/kg.The cumulative salt content of each soil layer decreased with increasing depth,and the higher the irrigation-evaporation ratio and the lower the groundwater salinity,the less the cumulative salt content in the soil.关键词
