摘　　要：以天津市港城大道园林绿地土壤为研究对象,研究不同灌水量情况下,采用智能化喷灌对盐碱地返盐的抑制作用,并提出抑制园林绿地土壤返盐的建议。结果表明,采用智能化喷灌在2.7 mm/d的灌水条件下,0~20 cm的水溶性盐含量整体呈下降趋势,降盐率为16.1%,并能较好地抑制表层土壤返盐。同时,节水效果最佳,浇水成本最低。Taking Tianjin Gangcheng road garden green soil as the research object,the effects of intelligent sprinkler irrigation on salt return in saline-alkali soils under different irrigation conditions were studied,the suggestions to inhibit soil salinity in garden green land were put forward.The results showed that,using intelligent sprinkler irrigation under the condition of 2.7 mm/d irrigation,the wa⁃ter-soluble salt content of 0~20 cm showed a downward trend overall,the salt reduction rate was 16.1%,and it could well inhibit the return of salt in topsoil.At the same time,the effect of water saving was the best,and the cost of watering was the lowest.
