Abstract: Drip irrigation under mulch (DM) has been widely promoted and applied in arid regions. The process of crop growth and surface water and energy transfer will change significantly under the dual control of mulch and drip irrigation compared with those under the traditional border irrigation under mulch (BM) method, which will further affect the regional eco-hydrology process. The Hexi Corridor has become the largest seed maize production base in China due to its abundant solar radiation, and heat resources and large diurnal temperature difference. Unlike grain maize, seed maize can be divided into female and male parent plants. The growth conditions of the parent plants differ; male plants are planted 7–14 d later than female plants to produce preferable fertilization conditions, which distinctly influences the energy transfer process between the different parent plants and the soil and ultimately leads to significantly different plant water consumption in the maize field.
