一种农作物拔除和栽培装置，包括至少一个杆，该杆上具有至少一个倾斜边缘，该倾斜边缘从支撑件延伸，至少部分地穿过待栽培的行或从其上拔除农作物和/或叶子。杆由支撑结构以悬臂方式可旋转地支撑，使杆的外端自由。杆可以在大致横向于设备沿着作物行的移动方向的方向上延伸穿过作物行，或者可以相对于作物行向后倾斜以提供自清洁作用。杆在土壤表面下旋转，并且当杆沿着移动时将农作物和树叶连根拔起，旋转方向与设备的行进方向相反。可以提供一对杆，一个杆位于正在耕作的行的每一侧或作物将被连根拔起的位置，其中至少一个杆延伸超过行宽度的50%的距离。该对杆的外自由端可以重叠。液压缸或类似物可以与一个或所有杆相关联，以使杆水平地移动远离作物行的中心，并使杆返回到其正常的拔根、耕作位置。通过这种布置，该装置可以用于栽培方法中，在看到或自动感测到植物的存在时，杆或多个杆沿着行远离农作物植物移动，从而将叶子连根拔起并仅在农作物之间对土壤进行耕作。
Crop uprooting and cultivating apparatus which includes at least one bar having at least one angled edge thereon that extends from a support at least partially across a row to be cultivated or from which crops and/or foliage are to be uprooted. The bar is rotatably supported by a support structure in cantilever fashion, leaving an outer end of the bar free. The bar may extend across a crop row in a direction generally transverse to the direction of movement of the apparatus along the row, or may be angled rearwardly with respect thereto to provide a self-cleaning action. The bar rotates beneath the surface of the soil and uproots crops and foliage as it moves along, the direction of rotation being in a direction opposite the direction of travel of the apparatus. A pair of bars may be provided, one being located on each side of a row being cultivated or where crops are to be uprooted with at least one of the bars extending a distance of more than 50 percent of the width of the row. The outer free ends of the pair of bars may overlap. A hydraulic cylinder or the like may be associated with one or all bars to move same horizontally away from the center of the crop row and return same to its normal uprooting, cultivation location. With this arrangement, the apparatus may be utilized in a method for cultivation, the bar or bars being moved away from crop plants along the row upon sight or automatic sensing of the presence of the plant and thus uprooting foliage and working the soil only between the crop plants.
