Abstract:: For improving irrigation water utilization efficiency of clay loam in arid and semi arid region, using biochar as soil conditioner to reformed cultivated soil at Hetao irrigation area, we simulate water infiltration process with three classical infiltration models to seek a suitable infiltration model to describe cultivated soil infiltration process and select a most effective proposal to improve the irrigation efficiency in semiarid climate area. There were four biochar application rates (10 t/hm², 20 t/hm², 30 t/hm², 50 t/hm²) and we carried out the double loop infiltration test under irrigated condition to measure soil moisture content, infiltration rate and cumulative infiltration amount during the crop growing period for the four applications. The Green-Ampt model, Philip model and Kostiakov empirical formula were used to simulate the infiltration process of experimental group and control group (CK). The results show that the effect of group of 30 t/hm² was most significant and application layer (0 to 40 cm) infiltration rate increased by 44.6%, soil moisture content increased by 8.9% and cumulative infiltration volume increased by 45.45%. Compared with the infiltration process fitting results of three models, the Kostiakov empirical formula fitting presented better tendency and was close to the testing values, which could provide the theory basis for soil improvement in the study area.
