Study on the Infiltration Characteristics of Single Filmed Hole and Its Mathematical Model under Filmed Hole Irrigation

The paper researches single filmed hole infiltration law and the relation between filmed hole infiltration and vertical infiltration under adequate water supply based on indoor experimental data,suggests the filmed hole infiltration model based on Kostiakov infiltration equation,finds the connection between film hole infiltration parameters and vertical infiltration parameters,and determines the single filmed hole infiltration model according to vertical infiltration data.These research results have laid a foundation for further study of the theory and technology of filmed hole irrigation.
