The utility model discloses a
system capable of switching
spray irrigation and infiltrating
irrigation. A water collecting tank is horizontally arranged at the corresponding position of the lower edge of a photovoltaic panel unit; the water collecting well is arranged below the water outlet end of the water collecting tank; the buried
pool is connected with the water-collecting well through a water-collecting pipeline; the
water storage tank is arranged on the ground; an inlet of the water suction pump is connected with a water suction
pipe extending to the bottom of the buried water tank, and an outlet of the water suction pump is connected with a water inlet pipeline communicated with the
water storage tank; the sprinkling
irrigation unit is connected with a water outlet pipeline extending out of an outlet of the
water storage tank, so that sprinkling
irrigation can be performed on a soil body below the photovoltaic panel unit; the infiltrating irrigation unit is connected with a water outlet pipeline extending out of an outlet of the
water storage tank, and therefore infiltrating irrigation can be conducted on the soil body below the photovoltaic panel unit. According to the invention, occupation of limited space on the ground is greatly reduced, balanced sprinkling irrigation is realized through unified collection and distribution, and switching of irrigation
modes can be carried out.
