The invention discloses a picking device for agricultural product planting. The picking device comprises a picking box fixedly provided with a handspike, a hollow structure of which the two ends are communicated with each other is adopted for the picking box, the inner wall of one side of the picking box is provided with a mounting hole, and a detachable filtering net is mounted at the other sideof the picking box; first cutting bases are symmetrically and rotatably connected to the two sides of the inner wall of the picking box through first rotary shafts, and multiple second cutting bases are fixedly connected to the inner wall of the picking box through multiple mounting rods; multiple mounting bases are further fixedly mounted inside the picking box, a second rotary shaft is rotatablyconnected to each mounting base, and an elastic structure is mounted between each mounting base and the corresponding second rotary shaft. The picking device has the advantages that flower stems withdifferent thicknesses can be quickly picked, and meanwhile, in the picking process, acting force utilized for separating the flower stems from chrysanthemum flowers is small, the probability that thechrysanthemum flowers are damaged is lowered while the flower stems and the chrysanthemum flowers are easily separated, and the picking quality is improved.
