The invention discloses drip irrigation equipment for plants in a hydro-fluctuation belt and relates to the field of water conservancy and hydropower engineering, in particular to the drip irrigationequipment which is used for plants in the hydro-fluctuation belt, can realize automatic water supplementing and meets irrigation of the plants in the hydro-fluctuation belt. The drip irrigation equipment is arranged above the plants in the hydro-fluctuation belt and is characterized by comprising a water storage barrel, a water inlet pipe, a drip irrigation pipe and an exhaust pipe, wherein the water inlet pipe is arranged at the top of the water storage barrel, the drip irrigation pipe is arranged at the lower part of the water storage barrel, the exhaust pipe is vertically arranged at the top of the water storage barrel, the water storage barrel, the water inlet pipe, the drip irrigation pipe and the exhaust pipe are communicated. Water is stored at a high water level, drip irrigation isperformed at a low water level, the drip irrigation equipment can adapt to water level change of the hydro-fluctuation belt, the equipment does not require artificial maintenance, the treatment costis reduced, water in a reservoir is used for irrigation, and water is saved; through reasonable calculation, applicable sizes are designed, the water level changed cyclically when the reservoir operates normally, and after the water level lowers, water stored in the drip irrigation equipment can meet demands of plants.
