The utility model discloses a field planting plate structure for
greenhouse vegetables, which comprises a floating plate, a plurality of planting ports arranged at equal intervals are arranged on the floating plate, fixing cylinders for fixing vegetables are mounted in the planting ports, a
gas pipeline is arranged in the floating plate, one end of the
gas pipeline is connected with an external gas source, and the other end of the
gas pipeline is connected with a gas outlet. And the other end of the gas pipeline extends into the
nutrient solution at the bottom of the floating plate. The roots of the vegetables are clamped and fixed through the fixing clamps at the bottoms of the fixing cylinders, the vegetables are prevented from falling into the
nutrient solution from the planting openings, meanwhile, the planting depth of the vegetables is kept consistent, and later-period management is facilitated; the gas conveying pipeline is arranged in the floating plate, and an external gas conveying device is used for providing
oxygen for vegetable roots at the bottom of the floating plate through the gas conveying pipeline, so that
necrosis of the vegetable roots due to
oxygen deficit is avoided.
