Abstract

Abstract

Brilliant Blue FCF was used to trace water flow in cotton field of mulched drip-irrigation using brackish water. 13 cross sections were dug before irrigation, during irrigation and after irrigation, respectively, for observation of the movement of wetting front. The soil moistures were in-situ measured at 3 120 points by using MP406 moisture probe and 1 430 soil samples were sampled to analyze soil salinity by extracting soil water with 1:5 of soil to water, while cross sections were divided as each grid 10 cm×10 cm. The meteorology data were measured by WATCHDOG. The results show that the dye tracer can trace soil water flow and salinity transport obviously. There are two infiltrating states for soil water and salinity transport characters in field under film mulched drip-irrigation: point source infiltrating in the direction vertical to drip irrigation pipe and approximate line source infiltrating along with drip irrigation pipe. The velocity of soil wetting front movement was 8cm/h under the present irrigation. The soil salinity near the dripper was leached by irrigation water; however, the salt accumulated in the surface soil without film mulch. The wetting front extended with the irrigation time, and the spreading distance was similar to that with no plants. For efficient use of soil water, the reasonable irrigation quota for the present planting pattern of one film, one irrigation pipe and four row cottons was 29.4-69.8 mm in the study area.
