【摘要】 活化水技术可使水的理化性质发生显著改变,提升水分子活性,其中磁化、去电子、增氧等灌溉水活化技术能够改良土壤理化性质,提高水肥利用效率,促进农田作物生长及增产,并且因其具有低耗能、无毒无害且高效快速的特点已受到广泛关注。本文介绍了磁化、去电子、增氧三种较常见的灌溉水活化技术对普通水理化性质的改善效果,及其应用于农业生产过程中对土壤理化性质的改良作用;同时着重介绍了磁化水灌溉对作物生长的影响以及对土壤盐渍化的改良效果,并指出其中存在问题,以促进活化水灌溉技术在农业中的推广应用,这对正处于淡水资源短缺、土地质量下降的我国干旱半干旱区实现农业节水增效、可持续发展具有重要的理论和实践意义。更多还原

【Abstract】 Activated water technology can significantly change the physicochemical properties of water and enhance the activity of water molecules. Magnetization, de-electronation, and oxygenation techniques can improve the physicochemical properties of soil, promote wateruse efficiency, and soil nutrient-utilization efficiency, and increase the growth and yield of farmland crops. Activated water technology has attracted the attention of many researchers for its low energy consumption, innocuity, and high efficiency. This paper introduced the benefits of three common irrigation water activation technologies—magnetization, de-electronation, and oxygenation—and their effects on the physicochemical properties of soil in agricultural production. We described the influence of magnetized water irrigation on crop growth and improvements in soil salinization. In addition, we highlighted existing problems in the popularization and application of activated water irrigation technology in agriculture. This study was of considerable theoretical and practical significance for the realization of agricultural water conservation, efficiency, and sustainable development in arid and semi-arid areas where freshwater resources were scarce and land quality was declining.更多还原
