Abstract:
      Based on lab experiment under film hole single-line interference infiltration with different fertilizer solution concentration,cumulative infiltration volume,wetting front transport distance and the distribution of soil water content with different fertilizer solution concentration were studied.The laws of cumulative infiltration volume and transport distance of wetting front increased with the increase of solution concentration were presented,mathematical models for cumulative infiltration volume under film hole infiltration and wetting front transport distance were developed,the models were verified by measured data,wetting front transport distance in the same time and the soil water content at the same depth increased with the increase of solution concentration.
