Improved fruit tree root three-dimensional irrigation device

The utility model relates to an improved fruit tree root three-dimensional irrigation device which comprises an annular irrigation assembly and a water supply assembly, the annular irrigation assembly is buried in the surface layer of the land and arranged around the root of a tree, the annular irrigation assembly comprises an annular water distribution section and a water inlet pipe section, and the annular water distribution section further comprises an arc-shaped water distribution pipe and a C-shaped water distribution pipe. The arc-shaped water distribution pipe and the C-shaped water distribution pipe are connected into a closed annular water distribution pipe through threads at the opening parts; and the lower part of the water inlet pipe section is communicated with an inclined pipe section which extends downwards to the lower part of the annular water distribution section. According to the device, first-time three-dimensional fertilization and irrigation are realized, so that for straight growth of t
