Abstract:
      Based on experiments of fertile solution infiltration,the main effects of irrigation quota on infiltration rate were studied with a 150 cm groundwater table.The results indicate that the average infiltration rate reduces with the increase of the irrigation quota.The average infiltration reduction rate increases with the increase of the irrigation quota.The changing of the soil water content increases with the increase of the irrigation quota.The wetting front transport distance and the water enternce in the groundwater increase with the irrigation water quota increasing.
