Abstract: A hydroponic apparatus includes a cultivation tank and planting containers. The cultivation tank includes an inner space and a top planting groove. Each of the planting containers includes a container body and a container brim The planting containers can be arranged on the planting groove along a width direction of the planting groove, and the planting containers can be moved along a length direction of the planting groove. A hydroponic method includes: placing the planting containers at n positions arranged along the planting groove, wherein each position corresponds to a plant growth and development stage, and is consistent with an order of the plant growth and development stages; and harvesting the plant at the position n at a specified time point, and moving the planting containers at other positions one by one to the positions corresponding to the next plant growth and development stages.

Abstract: The present invention provides a transplanting equal-dividing mechanism which includes a driving mechanism, a module fixing plate, a robot connecting rod, a linkage and a clamping jaw device, wherein the driving mechanism is disposed above the module fixing plate, a bottom of the module fixing plate is provided with a guide rail, the guide rail is provided with a plurality of sliders thereon, the clamping jaw device is connected below each slider, each clamping jaw device is provided with two linkages on its back surface, and the linkage is rotationally connected to a back of the clamping jaw device. The clamping jaw device is driven by the drive mechanism to achieve automatic separation and aggregation, and the clamping and placing works of plants in the transplanting process are realized by utilizing the clamping and retracting functions of the clamping jaw devices.
