摘要
通过非充分供水条件下的3种流量和4种灌水温度对SO2-4、Na+、Cl-和Ca2+的运移试验,分析了温度对盐分离子运移的影响。认为4种盐分离子在湿润土体中均受到灌水温度的影响,该研究将为膜下滴灌技术的进一步推广和探索盐碱地的改良措施提供有益的思路。
Based on the experiment of influence of four various irrigation water temperatures on four salt ions transportation (SO^(2-)_4, Na^+, Cl^-, Ca^(2+)) under insufficient water supply with three various discharges, this paper analyzed the influence of temperature on salt ion transportation. The author put forward that irrigation water temperature has effect on all the four salt ions in wet soil. The research result will help to farther spread technology of drip irrigation under plastic mulch and search improvement measure for saline-alkali land.
