Soybean, corn and other crops for planting ridge land for the first time can be replaced by deep furrow ditch, the depth does not break the plow the bottom of the soil, there cited drought and seepage water seepage waterlogging two-way regulatory function, out of the trench It is also the place where the head of a shovel used for operations, such as earthwork of a top-dressing and top dressing (fertilizer) The deep furrows shown in Figure 1 can be equipped with three groups of small four-wheel tractors with a large social ownership of 16.2kW.
