[0037] The fixing assembly includes a fixing sleeve 61 for limiting the position of the lysimeter sensor 3. The inner sides of the fixing sleeves 61 are connected to each other by metal plates. Multiple fixing sleeves 61 are connected to each other by metal plates and can be adjusted together by a pull rod 62. The bottom of the placement plate 51 is slidably connected to the pull rod 62. The bottom end of the pull rod 62 is connected to the top of the fixing sleeve 61. The pull rod 62 can drive the fixing sleeve 61 to move inside the fixing cylinder 2. The surface of the lysimeter sensor 3 is threadedly connected to a push ring 63. The inner side of the push ring 63 is circular. The push ring 63 slides inside the fixing sleeve 61.
