And slope planting survival rate of plants is increased

The utility model relates to the technical field of slope greening. The saving type ecological irrigation device capable of improving the slope planting survival rate of the plants comprises a water blocking piece and an irrigation mechanism which are arranged in the slope inclination direction at intervals, and the water blocking piece comprises a horizontal water blocking face and two side plates which are arranged at the two ends of the water blocking face respectively and extend in the slope upward inclination direction; a water storage area is formed between the two side plates and the water blocking surface; the water blocking face and the side plates are provided with bottoms inserted into soil and tops exposed out of the surface of the soil, and water seepage holes are formed in the surfaces of the bottoms of the water blocking face and the side plates. The surfaces, facing the water storage area, of the water blocking faces and/or the side plates are connected with a pluralityof nutrition columns, ea
