Abstract: Water shortage is a major challenge to the agricultural irrigation. However, reclaimed water will effectively ease the current situation. Because nutrient concentration and organic matter content are higher in reclaimed water, its improper use will bring adverse effect on crop growth and soil environment, may lead to agricultural non-point source pollution. Research status and existing problems in reclaimed water irrigation at home and abroad are summarized according to the effects of reclaimed water on crop growth, soil nutrient and soil enzyme activities in this paper. The following aspects should be researched deeply in the future: the effect of characteristics of soil nitrogen supply in crucial crops growth periods, response characteristics of soil enzyme activities on long-term reclaimed water irrigation, soil nitrogen nutrition diagnosis and threshold value range with reclaimed water irrigation, the effect of reclaimed water irrigation on fruit ultrastructure.
