抄録
The field performances of slot openers and residue handling devices have been studied experimentally in conjunction with the role of micro-managed surface residues which are advantageous for seeding and moisture conservation. Hairpinned residues and the area of soil disturbance were identified as the key factors in evaluating drill performance. The drill operations of four slot openers including a bubble coulter, a V-shaped, a VRA- and a VRB-slot openers were demonstrated. Regarding of hairpinned residues, a VRA- and a VRB-slot openers showed practically significant results to prevent from incorporation of hairpinned residues whereas a residue handling device acted to push the residues away from the slots. A bubble coulter and a V-shaped slot openers pressed the surface residues into the slots. A minimal area of soil disturbance occurred with a V-shaped and a VRB-slot openers. On the contrary, a bubble coulter disturbed a relatively wider area under bare soil (0t/ha) or lower level of residue density (2t/ha). A VRA-slot opener similarly disturbed a wider area under the given conditions. It can be concluded that a VRB-slot opener showed an acceptable practicability under the setting conditions. This unit could perform an ideal seedbed making actions in terms of the compressed slot, soil penetration resistance, hairpinned residues, and minimal area of soil disturbance so as to secure a higher percentage of seed germination and soil moisture conservation.
