盐碱地膜下滴灌土壤水盐变化规律试验分析

Experimental Analysis on Saline-alkali Soil Drip Irrigation Soil Water and Salt

膜下滴灌技术是一种既节约水资源又能适时调控土壤水盐运移的灌溉技术,在新疆已得到普及推广。在田间情况下,研究盐碱地膜下滴灌土壤水盐变化规律,对合理控制盐碱地土壤盐分具有重要的指导意义。试验结果表明,随着灌水时间和灌水量的增加,盐碱地上层土壤水盐整体呈现下降趋势,待灌水期结束后,盐分又逐步回升。

Drip irrigation technology is a Method that save water resources but also regulation of soil water and salt transport in irrigation technology in a timely manner which has been Universaled and Promoted in Xinjiang. Field case, the experimental Analysis on saline -alkali soil drip irrigation is an important reasonable guiding significance to control Soil Salinity. The results showed that：With the increase in the amount of irrigation time and irrigation , saline upper soil water and salt as a whole show a downward trend after the end of the pending irrigation period , salt and gradually picked up.
