In order to make full use of Shallow groundwater, reduce the amount of water used for irrigation, and improve the efficiency of agricultural water resources utilization in the water shortage area of Huaibei Plain, this paper carried out experiments on wheat groundwater use based on different soils and different groundwater depths. The typical shajiang black soil and yellow fluvo-aquic soil in Huaibei Plain were selected for the experiments. The groundwater control depth was 10 levels within the range of 0-4 m, and the experiment was carried out to measure the evapotranspiration of the crops. The variation of phreatic water evaporation with soil depth and groundwater depth at six different growth stages was summarized. The results showed that the phreatic water evaporation of wheat decreased with the increase in groundwater depth. Under the same burial depth, the evapotranspiration of yellow fluvo-aquic soil was greater than that of shajiang black soil. The above results showed that the groundwater use efficiency was the highest in the case of yellow fluvo-aquic soil and 1.0 m of groundwater depth. [ABSTRACT FROM AUTHOR]
