As shown in fig. 3, a plurality of energy dissipation blocks 3-2 which are sequentially communicated are arranged in the energy dissipation device, the energy dissipation blocks 3-2 are of a structure in which a circuitous channel is arranged, a plurality of water inlet holes are formed at the beginning of the channel so that water in the pipeline can conveniently enter the energy dissipation channel, and two water outlet holes are formed at the tail end of the channel to form an outlet. The periphery of the water outlet is provided with an anti-blocking protective net 3-1 of the water outlet. The root zone irrigation mainly supplements water for the soil of the root zone of the fruit tree through water outlet holes formed in the pipe wall, and the energy dissipation blocks 3-2 realize flow distribution and energy dissipation of irrigation water, ensure that the irrigation water flows out in a drop shape, and prevent the damage to the soil structure of the root zone due to the outflow of bunched water flows; and the anti-blocking protective net 3-1 of the root irrigation water outlet can prevent soil particles from blocking the water outlet hole.
