Soil water accumulation time for different soil’s initial water content, bulk density, sprinkler application rate and soil texture were derived by the finite element method, and these data were used as a training database for the neural network. In this study, a mathematical model of soil infiltration for sprinkler irrigation with water and fertilizer integration machines was developed. Therefore, it is necessary to provide a feasible scientific and theoretical basis for developing a reasonable application rate. If the value is too large, the equipment will produce runoff if it is too small, the equipment will run too long and waste energy. ![]() ![]() The application rate for sprinkler irrigation of water–fertilizer integration machines is an important technical parameter for efficient operation.
