The invention discloses a method for counter-slope surface soil thickness increasing,permeation increasing and soil preparing of slope croplands, and relates to a method for permeation increasing and soil preparing of slope croplands. The method aims at solving the technical problems that at present, through a method for preventing and controlling water and soil loss of slope croplands, the height equality is hard to achieve, the occupied cultivation area is large, surface soil layers are disorganized, and the output reduction is caused. The method includes the steps of conducting shoveling in the direction opposite to the water running direction of a furrow and upwards pushing topsoil to form an inner channel, digging a groove in the pit bottom of the inner channel, filling the groove with a mixture of straw, fine sand and topsoil, placing deep soil dug out of a water storage permeation increasing groove on the lower portion in the water running direction of the furrow, and conducting backfill on the surface of the inner channel and the surface of a counter-slope surface soil ridge so that the bottom of the inner channel can be located on the same horizontal line. The method has the advantages that the rainfall water level can be reduced, the water and soil conservation effect is improved, the soil and nutrient loss of slope cropland surface layers is reduced, the ridge directions of the slope croplands are not changed, no land area is occupied, and the method is particularly suitable for slope croplands in black soil regions in the Northeast with vast territory, sparse population and shallow topsoil.
