Water fixing device for land reclamation sloping field and terraced field

In order to overcome the defects in the prior art, the invention provides a land reclamation slope terrace water fixing device which comprises a T-shaped hard support buried at the bottom of a terrace pit through a gravel soil layer. The upper portion of the gravel soil layer is filled with planting matrixes after geotextile is laid, and terrace planting pits are formed. A drainage channel is arranged on one side edge of the terrace pit from top to bottom along the sloping field, and an adjusting drainage device is arranged between the terrace planting pit and the drainage channel. The drainage device comprises a movable baffle and a fixed baffle. The lifting device is in signal connection with the control end, and after the control end conducts drainage control analysis, the control end controls the movable baffle to ascend and descend by sending a control instruction to the lifting device. Through the special structural design, the slope terrace water fixing device has good water fixing and retaining capaci
