The invention discloses a system for regulating the loach water quality in a high-salt planting and breeding mode. The system comprises a high-salt planting and breeding pool, a sun shield, bases, natural plant planting pots, a sandstone plate, a microbial incubator, a thermometer body, a camera body, a regulation system control panel, a connecting column, an oxygen extractor body, a regulation system control shell, a water quality sensing module, an information receiving module, an information processing module, an information storage module, a GPS positioning module and an instruction outputmodule, the sandstone plate is arranged on the inner wall of the bottom of the high-salt planting and breeding pool, a plurality of mounting grooves are formed in the top of the sandstone plate, natural plant planting pots are arranged at two sides of the top of the sandstone plate, and the microbial incubator is arranged at the center of the top of the sandstone plate. The system for regulatingthe loach water quality in the high-salt planting and breeding mode abandons traditional manual monitoring, adopts machine monitoring to achieve time and labor saving and convenient and accurate monitoring, and allows a user to regulate the water quality according to the observation result in order to facilitate user operation.
