Sustainable development and Oasis Ecological Environment are stable.Xinjiang is located in arid area, and little precipitation, evaporation capacity are big, the soil salinization
Problem becomes increasingly conspicuous, and causes scientist and the extensive concern of society.Although the method in improvement soil salt-soda soil is very
Many, but salinity is not departed from soil, and if agricultural is poured water, measure is unreasonable, it will re-initiation Soil Secondary
Salination.
Though farmland underground closed drainage early has application in China, but utilizes closed drainage improvement salt-soda soil to test still in limit
The stage that limit is promoted.Closed drainage salt reduction is in compliance with the moisture-salt transport rule of " salt comes, salt goes with water " with water, will fill
The water body point having dissolved soil salt and permeate the ground is drained by pipeline, thus reach effectively to reduce soil salt content,
Controlling groundwater level, improve the purpose of soil physical and chemical property.Domestic there are some researches show, closed drainage to Cl-, Na+,
SO42-plasma has preferable leaching.
