When the root growth rate is between 3~10%, a first rotating mechanism is triggered to drive the turntable to rotate to a low water level to make the nutrient liquefied The water mist presents a low water level in the plant tube; when the root growth rate is lower than 3, the first rotating mechanism is triggered to drive the turntable to rotate to a high water level angle, so that the liquefied nutrient water mist is in the plant There is a high water level in the pipe. The smart water-fog crop monitoring and cultivation system according to claim 1, wherein an image capturing unit is also provided on one side of the transparent plant tube to capture images of the junction between the roots of the plant and the surface of the liquid nutrient water in the plant tube; When the ratio of the width of the root of the plant at the junction of the water surface of the liquid nutrient water in the plant tube to the maximum width of the plant root is greater than 50%, a drain valve set on the plant tube is controlled to open to Drain the liquefied nutrient water in the plant tube until the ratio of the width of the plant root at the junction of the plant root and the water surface of the liquid nutrient water in the plant tube to the maximum width of the plant root is less than 30%. The intelligent water fog farming crop monitoring and cultivation system as described in claim 1, which further includes a second rotating mechanism that can be controlled by the arithmetic processing device to output rotational power and a second rotating mechanism for tracking the position of real-time sunlight to generate a position Signal light source tracking module; the planting tube includes a first tube section extending in the opposite direction, a second tube section, and a plurality of plantings connected between the first tube section and the second tube section and provided with a plurality of planting holes Pipe section; the planting carrier further includes a base, the first pipe section and the second pipe section are rotatably pivotally connected with the two support rods of the base, the second pipe section is linked with the second rotating mechanism; the calculation processing device interpretation After processing the position signal, a position driving signal for driving the second rotating mechanism to perform a corresponding operation is generated, so that the second rotating mechanism drives the planting pipe section to rotate to the angular position that can receive the sunlight. The smart water-fog crop monitoring and cultivation system according to claim 7, further comprising a conveying pipe, one end of the conveying pipe is connected with an outlet of the mixing tank, and the other end forms an enlarged pipe section with a larger pipe diameter. The inner peripheral surface of the enlarged pipe section is provided with a ring concave edge, and the outer peripheral surface of the first pipe section is provided with a ring The ring concave edge forms a rotatably fitted and positioned ring flange for the nutrient mist generated by the mist generating device to pass through the delivery tube and the first tube section to be rotatably transported into the plant tube . The intelligent water-fog crop monitoring and cultivation system according to claim 1, which further includes a plurality of planting structures filled in the plurality of planting holes, and each planting structure includes a planting structure for covering the supply A support bracket on the periphery of the planting hole and a planting net group, the support bracket includes a lower abutment sheet and at least one support connected to the lower abutment sheet for supporting the planting net group, the planting net group includes an upper abutment Sheet and a plurality of meshes connected to the upper yoke, the plurality of meshes are densely arranged with a plurality of meshes and are connected to each other and are stacked in the supporting bracket; the upper yoke ring is provided with a ring flange, and the lower The yoke ring is provided with a ring groove for the ring flange to be fitted and positioned, so that the upper yoke of the planting net group is positioned on the lower yoke of the support bracket.
