英文摘要	为给再生水在农业上的利用提供依据,采用盆栽试验的方法,通过对冬小麦主要生育期形态和生理指标的测定以及产量构成因素的分析,研究了再生水(二级水、三级水)灌溉对冬小麦形态及光合特性的影响.结果表明,再生水灌溉下冬小麦的株高及叶面积要高于清水灌溉处理,且三级水灌溉的促进作用更明显;在产量构成因素中,三级水灌溉处理各项指标较清水灌溉处理略高,二级水灌溉处理在千粒重指标上要高于清水灌溉处理,其余指标较清水灌溉处理低;在光合和蒸腾速率方面,三级水灌溉处理冬小麦较其他处理表现较高.由此可见,再生水对冬小麦的生长有一定的促进作用,且三级水灌溉对冬小麦有一定的增产作用,但二级水灌溉增产效果并不显著.; The effect of reclaimed water (secondary effluent, tertiary effluent) irritation on winter wheat was studied through pot experiments. The morphologic and photosynthesis indicators at key growth period and yield components were analyzed. The result show that the stem height and leaf area of wheat irrigated by reclaimed water are higher than those by fresh water, and the performance treated by tertiary effluent is better than that of secondary effluent. For the yield composition of wheat, each yield components of the wheat irrigated by tertiary effluent are higher than that by fresh water. For secondary effluent, only 1000-grain weight of wheat irrigated by secondary effluent is heavier than fresh water while others are lower. Wheat irrigated by tertiary effluent has highest photosynthetic rate and transpiration rate after elongation stag among the treatments. In condusion, the reclaimed water produced by current process in Beijing can benefit winter wheat growth in some extent, the tertiary effluent could promote the yield of winter wheat while the effect of the Secondary effluent is not remarkable.
