Aiming to study the effects of different biochar species and their application amounts on soil water infiltration in newly reclaimed area, a vertical one-dimensional water infiltration experiment was conducted with two biochar species (corn stalk biochar A and rice husk biochar B) and three application amounts gradients (2%, 4% and 8%) and no biochar application (CK) in seven treatments. The results showed that except for low-application amount of rice husk biochar treatment (B2), the addition of biochar delayed the process of soil water infiltration in the newly reclaimed area, and corn stalk biochar was superior to rice husk biochar. The infiltration time of the treatments (A2, A4 and A8) with the addition of 2%, 4% and 8% corn straw stalk biochar was gradually increased with the application rate, and compared with that of CK, the infiltration time was increased by 35.0%, 46.0% and 59.1%, respectively. However, only the 4% application amount treatment (B4) in the rice husk biochar group delayed water infiltration, and the infiltration time was increased by 28.5% compared with that of CK. Meanwhile, the addition of biochar reduced the initial infiltration rate of soil and the migration distance and cumulative infiltration of wetting fronts within the same infiltration time, and the effects of biochar species and its application amounts on these three indicators were similar to the effects on infiltration time. Both biochar additions increased the soil surface water content by percentages ranging from about 2.2% to 20.3%, and the soil water retention capacity of both biochar was significantly better under the high application amount treatment conditions than the medium and low application amounts. The distance and time of wetting front migration were in accordance with the power function, and the Philip model can better simulate the water infiltration process of newly reclaimed soils under different species and application amounts of biochar treatment. In general, the treatment of corn stalk biochar addition at 8% was beneficial to improve the problem of rapid soil water infiltration and weak water retention capacity in newly reclaimed areas, which was a more recommended choice for rapid maturation and utilization of newly reclaimed areas.
