Abstract
[目的]对近年来国内外关于微润灌溉技术的研究成果进行综述,探讨微润灌溉的未来研究方向, 为微润灌溉制度和灌溉参数的制定及该节水技术的推广提供依据。[方法]总结微润灌溉的发展历程和应 用现状,微润灌溉条件下土壤水分运动规律,微润灌溉对作物生长的影响,并分析微润灌溉技术的不足之 处。[结果]微润灌溉是一种新型地下灌溉技术,以连续灌溉方式不间断地向作物根系供应适量水分,使植 物吸水过程与田间灌溉过程具有同步性,灌水量与植物耗水量相匹配,实现无胁迫灌溉,改善作物品质和 产量。该技术已成为国际领先的仿生型连续灌溉系统,在干旱半干旱地区具有广阔的应用前景。[结论] 今后应加强的研究领域主要包括:微润灌溉对土壤养分运移的影响;微润灌溉对不同种植模式作物生长的 影响;微润灌溉对农田生态系统温室气体排放的影响。</p
