发明名称 No-till field implement
摘要 An implement for agricultural field work is primarily useful for preparing a field for no-till planting and comprises a wheel carried frame for carrying a massive fertilizer hopper which has apertures in its bottom portion through which fertilizer flows at a metered rate into feed tubes which carry the fertilizer to furrows formed by double-disc ground openers mounted on the frame. The openers aerate the soil and chop crop residues remaining on the ground surface from the previous crop. Hoes attached to the openers draw a portion of the soil displaced from the furrows back into the furrows after the fertilizer is deposited therein.
