Spraying pipeline for planting of peonies under walnut forest

The invention discloses a spraying pipeline for planting of peonies under a walnut forest. A water outlet groove (10) and a water inlet groove (7) are formed in the upper surface and the lower surface of a spraying pipeline main body (1) respectively, then two separating plates (6) are arranged in a cavity of the water outlet groove at an interval, three rectangular cavities are formed in the water outlet groove, a water passing hole (11) is formed in the bottom of the right end of the water outlet groove between the two separating plates, and water distributing holes (12) are formed in the left ends of the two separating plates, so that front water spraying nozzles (2) and back water spraying nozzles (5) which are arranged on two side surfaces of the water outlet groove can realize uniform water feeding effectively. With the spraying pipeline, walnuts and the peonies can be sprayed simultaneously, and the spraying pipeline has the characteristics of being simple in structure, convenient to operate and the li
