Abstract: Drought is the key restricting agricultural development, using water-saving agent to achieve the purpose of watersaving and crop production.h is a effective way for agricultural water saving research. This paper aimed to study the effect of water-saving agent on soil water content, traits and yield of wheat on tillage field . The results showed that the use of watersaving agent can improve the botanical traits of wheat, increase soil moisture and yield. Botanical traits of wheat under different treatment showed： conservation tillage was better than conventional tillage and water irrigation was higher than dry land and seed dressing higher than deep application. Soil water content of conservation tillage was greater than the conventional tillage.Under conservation tillage conditions, soil water content of irrigation treatment was higher than the dry land treatment. Under the condition of conservation tillage soil water content of seed dressing was greater than the deep application and 1.66% higher than that of deep application. Conservation tillage yield was higher than that of conventional tillage and yield of irrigation higher than that of dry land and yield of seed dressing in different treatment was higher than 2.4 -6.3 kg/667m^2 than deep application.
