摘要：
In accordance with the present invention, there is provided a tillage conservation plow (100) for plowing the earth and exposing, on the surface of the earth, weeds and past harvest residue. The plow includes a hitch frame (1) and a framework (2) connected to the hitch frame. A support (10) is connected to the framework. The support is operable to allow the earth to pass unturned. A blade (4) is connected to the moldboard support. The support, in combination with the blade, is operable to place the weeds and past harvest residue on the surface of the earth without turning over the soil.
