PROBLEM TO BE SOLVED: To provide a lime sower, which has high spraying accuracy and facilitates sliding operation of a shutter plate.SOLUTION: A lime sower B is configured to perform fertilization by slidably disposing a shutter plate S outside a bottom plate V of a hopper K, and dropping and spraying a fertilizer easy to fly within the hopper K onto an agricultural field by rotating an agitator A disposed at the bottom of the hopper K. The shutter plate S and an overlap portion with the shutter plate S in the bottom plate V are bent respectively at a plurality of positions which are identical with each other in a cross sectional view, and a portion defined by each bending line L, L, L(L', L', L') is formed in a planar shape. Each spray hole H, H2 is formed in each planar portion on both sides of the specific bending line L(L') in the shutter plate S and the bottom plate V. |
