摘要
水资源严重短缺已经成为制约我国经济社会可持续发展的瓶颈,而且受生态环境用水不断加强的影响,农业用水变的愈加紧张,再生水的农业利用是缓解这种紧张局势的重要举措之一。现详细总结了国内外再生水的农业利用现状,从再生水灌溉水质标准、再生水灌溉对作物生长、土壤及作物生长环境的影响、再生水灌溉技术及灌溉制度等几个方面论述了其研究进展;最后对再生水灌溉存在的问题及今后的重要研究方向进行了分析。
Water shortage has already become the bottleneck for restraining the sustainable socioeconomic 1 development in China. As one of the important actions for solving water problem,the reclaimed wastewater utilizations at agriculture in China and overseas were described in this paper. The research advances were discussed from water quality criterion of reclaimed wastewater irrigation, the influences of reclaimed wastewater irrigation on crop growth and soil environment,irrigation techniques and schemes of reclaimed wastewater. Finally, the present problems on reclaimed wastewater irrigation and the future research aspects were analyzed.
