| Abstract: |
| Through indoor soil bin experiment, straw row application depth was studied in a one-dimensional vertical infiltration under the influence of soil water infiltration and distribution. The results showed that straw row application depth affected the cumulative infiltration amount, in the same infiltration time under different row application the depth, the cumulative infiltration amount order was 6 cm deep 4 cm wide > 4 cm deep 4 cm wide> 2 cm deep 4 cm wide >don’t put the straw; Straw row application transport rate of the vertical wetting front was the same with that of the cumulative infiltration; The depth of straw different row application distribution regularity of soil moisture content was similar, the soil moisture content contour lines were approximate semicircle near the straw row application and was straight near the wetting front, the greater the distamce at the straw row application farther， soil moisture distribution curve were more intensive; With the same infiltration time, the highest average soil moisture content was 6 cm deep 4 cm wide, the second was 4 cm deep 4 cm wide. Straw row application depth has influence on the soil water movement and distribution |
