Abstract: 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 water-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.

Key words: intelligent sprinkler irrigation, salt return, garden green space
