The utility model discloses an automatic wheat seedling hydroponic device, and relates to the technical field of wheat seedling hydroponic equipment, the automatic wheat seedling hydroponic device comprises a plurality of incubators stacked up and down, four corners of the top of the incubators are provided with support cylinders, the inner walls of the support cylinders are provided with support rods with adjustable positions, and four corners of the bottom of the incubators are provided with threaded cylinders; by adopting the automatic wheat seedling hydroponic culture device, three-dimensional and efficient culture of wheat seedlings is achieved, a plurality of culture boxes are stacked up and down, the ground space is greatly saved, the wheat seedling yield in unit area is increased, meanwhile, by means of the design of a transfer pump and a discharge pipe in the device, cyclic utilization of a culture solution is achieved, resource waste is reduced, and the cost is reduced. And by using the filter plate, the cleanliness of the culture solution is further ensured, and a stable nutrition source is provided for the growth of wheat seedlings. Under the combined action of the designs, the production efficiency and the resource utilization rate of the hydroponic wheat seedlings are remarkably improved, and the production cost is reduced.

A system for hydroponically growing plants, comprising an upper seed tray (100, 1401) configured to sit on a bottom tab (200, 1445). The upper tray includes a plurality of openings for holding soil and germinating seeds in the soil. The plurality of openings have contours that allow the roots of the growing plant to extend into the bottom tab. The tab is configured to hold an aqueous mixture of water and nutrient solution for the growing plant and comprises a lip around the top perimeter and at least one aeration device (240) for causing turbulence in the aqueous mixture that comes into contact with the roots of the growing plant. A method for growing plants using such a container is also disclosed.

This invention discloses a method for off-season hydroponic cultivation of Aralia elata buds based on plant hormone regulation, belonging to the field of hydroponic culture technology. This off-season hydroponic method optimizes the concentration ratio of indolebutyric acid (IBA), gibberellin (GA3), and salicylic acid through orthogonal experiments, combined with standardized branch pretreatment, hormone immersion, and ozone water culture management, to achieve efficient off-season cultivation of Aralia elata buds. This off-season hydroponic culture uses exogenous hormone regulation, optimized for the off-season dormancy characteristics of Aralia elata and the physiological needs of bud growth. It effectively activates the physiological metabolic pathways within the branches, quickly breaking the natural dormancy state, while providing suitable hormone guidance for bud differentiation and growth. This results in uniform bud sprouting and robust growth, solving the problems of late bud break from dormancy, slow bud growth, and large differences in growth vigor among different plants, laying a solid foundation for efficient off-season hydroponic production.

A method of increasing at least one of the chlorophyll-a concentration and the chlorophyll-b concentration in the leaves of a plant of the genus Hordeum which has been hydroponically grown from seed over a 2 to 4 week duration, including germinating the seed at from 20 to 40° C.; transferring the germinated seed into an aqueous hydroponic dispersion having a temperature of from 20 to 40° C. and containing NPs of magnesium aluminate (MgAl2O4) having a cubic spinel structure; for the duration of 2 to 4 weeks after transferring, maintaining the aqueous hydroponic dispersion at from 20 to 40° C. under dark period-to-light period cycling; and, for the duration of 2 to 4 weeks after transferring, periodically adding NPs of MgAl2O4 having a cubic spinel structure to the aqueous hydroponic dispersion to maintain the concentration of the NPs in the aqueous hydroponic dispersion at from 20 to 200 mg / L.

This invention provides a cultivation method for fruit and vegetable plants that enables harvesting at higher yields than conventional methods. [Solution] A method for cultivating fruit and vegetable plants, comprising the step of cultivating fruit and vegetable plants using a flooded hydroponic cultivation method, wherein the roots of the fruit and vegetable plants are not exposed to air during the seedling stage, and after the first flowering is confirmed, at least a portion of the roots are exposed to air during the dark period.
