摘 要:采用随机区组设计,研究了再生水(Reclaimed Water)灌溉黑麦草(Lolium perenne L.)、早熟禾(Poapratensis)、高羊茅(Festuca arundinacea)、结缕草(Zoysia japonica)、野牛草(Buchloe dactyloides)、麦冬(Radix liriopes)6种草坪草对土壤质量的影响,结果表明:(1)再生水灌溉能增加土壤养分,但根据养分在土壤中迁移的难易程度及不同草坪的根系分布特征,再生水灌溉输入的养分在土壤剖面分布不同;(2)再生水灌溉后的土壤虽然碱化度处在5%~10%弱碱化范围,但与自来水灌溉相比,其在土壤剖面中的分布有扩大的趋势;(3)在6种供试草坪草中,再生水灌溉后黑麦草和结缕草土壤质量最好,可见黑麦草和结缕草比较适宜进行再生水灌溉。As the shortage of water resource is seriously,reclaimed water has been used on turf as substitute of fresh.Two types of water(fresh water and reclaimed water) were used to irrigate 6 common turfgrasses(Poa pratensis,Festuca arundinacea,Zoysia japonica,Buchloe dactyloides,Radix liriopes,Lolium perenne L.) during 2006-2008.The research results showed that(1) Irrigation by reclaimed water increased nutrients of the turf soil in comparison to fresh water,at the same time,the content of the different nutrient elements was different in the different soil layer due to nutrient transporting in the soil and the root growth of turf.(2) ESP was in the range of 5%~10% of the soil irrigated by reclaimed water,but the alkalescence soil layer was enlarged.(3) After irrigating by reclaimed water,the soil quality of perennial ryegrass and Korean lawngrass was the best among six turfgrasses,So the two turfgrasses were adapt to be irrigated by reclaimed water.
