This thesis points out three conditions of favorable soil-returning volume,and gets the critical water-content coefficient of bed-irrigating sowing, andthinks that water volume, soil—returning in volume and initial soil water contentcoefficient affects differently the course and the result of infiltration, and revealsthe laws of variations of soil moisture content, and shows the different effect onsoil - wedded states of water volume, depth of seed ditch, soil apparent density,soil-covering depth,initial soil moisture content, width of seed ditch and soil-wedding states, and suggests that the soil-wedding state watering after sevendays is use to evaluate the quality of bed-watering seeding.
