微润灌溉技术研究进展及展望

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。

Progress and Prospects of Moistube Irrigation Technology Research

Objective] The research progress of moistube irrigation technology was reviewed to investigate the future research direction and provide available bases for the formulation of water-saving irrigation system and parameters. In addition, this review would play a key role in popularizing moistube irrigation technology.Methods] The paper summarized the development history and application status of moistube irrigation technology, soil water movement under moistube irrigation, effects of moistube irrigation on crops growth, etc. and the drawbacks of moistube irrigation technology were analyzed.Results] Moistube irrigation is an underground irrigation technology, having the advantages of uninterrupted adequate water supply for plant absorption and field irrigation were synchronicity. Moistube irrigation water was matched with plant water consumption. Meanwhile, moistube irrigation can come into being no-stress irrigation. In addition, moistube irrigation plays an important role in improving crop quality and yield. The moistube irrigation technology has become a leading international bionic type continuous irrigation system, and will have broad prospect of popularization in arid and semi-arid region.Conclusion] This paper reviewed the development history and application status of moistube irrigation, the research progress of moistube irrigation technology mechanism, migration rules of soil water and the effects of moistube irrigation on crop growth, and put forward the key research fields needed to be further study, including the effects of moistube irrigation on soil nutrient migration; the effects of moistube irrigation on crop growth with different planting patterns; the effects of moistube irrigation on greenhouse gas emissions of farmland ecosystem.
