To address the underutilization of muddy water irrigation in agriculture, as well as the issue of water scarcity in arid and semi-arid regions, and the variability of environmental temperatures across seasons, this study examined the soil water and nitrogen transport dynamics associated with fertilized muddy water film hole irrigation under various environmental temperature conditions. The study utilized an indoor film hole infiltration device to investigate the influence of 5 muddy water sediment concentration levels (0%, 3%, 6%, 9%, 12%) and 4 environmental temperatures levels (16 degrees C, 22 degrees C, 28 degrees C, 34 degrees C) on the cumulative infiltration of fertilization muddy water film hole irrigation. It also analyzed the distance of wetting front transport, moisture content in the wetting body, and changes in soil nitrate-nitrogen (NO3--N) and ammonium-nitrogen content (NH4+-N) transport. The infiltration concentration of the fertilizer solution is 600mg L-1. An increase in sediment concentration resulted in a significant decrease in cumulative infiltration. Specifically, when the muddy water sediment concentration rose from 0 to 12%, cumulative infiltration decreased by 43.01%. Conversely, raising the temperature from 16 degrees C to 34 degrees C resulted in a 36.52% increase in cumulative infiltration. Analysis of the wetting front distance revealed that, in comparison to clear water infiltration, a muddy water sediment concentration of 12% decreased the vertical wetting front distance by 27.41% and the horizontal wetting front distance by 26.56%. Moreover, the volume of the wetting body was inversely proportional to the muddy water sediment concentration. Compared to clear water, a muddy water sediment concentration of 12% caused a 60.85% reduction in wetting body volume, whereas increasing the temperature to 34 degrees C resulted in a 138.74% increase in wetting body volume. The distribution of NO3--N and NH4+-N content was also affected by muddy water and temperature. As the temperature rose to 28 degrees C, concentrations of both nitrogen species increased; however, their levels decreased at 34 degrees C, indicating that elevated temperatures inhibited nitrogen migration.The research results can provide scientific guidance for the effective use of muddy water for irrigation.
