The present invention provides a system for managing a plant of a plant cultivation apparatus. According to one embodiment, a plant management system may comprise steps in which: a processing unit acquires a picture including plant information by means of a user terminal; the processing unit recognizes the plant information included in the picture; the processing unit generates a plant management method in a plant cultivation apparatus on the basis of the plant information; and the plant management method is presented to a user through the user terminal.

A plant growing system having a growing chamber containing an aqueous growing medium and a growing atmosphere in which a plant is grown, a compound delivery system configured to deliver one or more compounds including nutrients mixed with surfactant into the growing atmosphere for plant stomatal uptake, an acoustical stimulation system configured to increase stomatal uptake, a growing medium oxygenation system configured for oxygenating, preferably hyperoxygenating or oxygen supersaturating, the growing medium which plant roots immersed therein take up oxygen longer before needing oxygen replenishment, and a plant lighting system configured to deliver ultraviolet wavelength filtered solar light to the plant for photosynthesis. The chamber preferably is a hyperbaric chamber, the growing atmosphere contains at least 0.06% carbon dioxide, the compounds are delivered in the form of atomized droplets, and the growing medium contains at least 2 mg/L oxygen in the form of nanobubbles diffused or dissolved therein.

A tray for a tray assembly for cultivating horticultural crops. The tray includes a reservoir to contain water and to receive a float in the reservoir to shield water contained in the reservoir from the external environment. The float is configured to receive a plant. A water inlet section is arranged adjacent the reservoir and comprising a water flow guide. The water flow guide defines a downward sloping guide surface configured to guide water received on the water flow guide into the reservoir under a level at which the float is arrangeable in the reservoir, and/or includes a throughflow opening to guide water into a chamber of the water inlet section in fluid connection with the reservoir. The throughflow opening includes a water permeable membrane to shield water within the water inlet section from the external environment. A horticultural method comprising using the aforementioned tray.

The current disclosure relates to a water level monitoring system for monitoring a water level in a hydroponic system, such as a LECA system being a lightweight expanded clay aggregate system or any other semi-hydroponic system or passive hydroponic system. The disclosure further relates to a corresponding method to monitor the water level in a hydroponic system, like for instance a LECA system or any other semi-hydroponic system or passive hydroponic system.

A plant cultivation device (1) which is an embodiment of a plant cultivation device includes: a cultivation bed (10) having a bottom surface (10a) on which a plant is placed and which is inclined; a first solution supply member (20); and a second solution supply member (30) extending along a direction (F1) in which the bottom surface (10a) is inclined. The second solution supply member (30) includes a plurality of nutrient solution discharge holes disposed along the direction (F1).

The invention discloses an application method of medium and trace nutrient elements for wrapper hydroponic system. The application method includes the following steps: providing a nutrient solution cultivation system as well as medium and trace element nutrient solutions for facility-based cultivation of wrapper; the medium and trace element nutrient solutions are applied in the cultivation of wrapper; wherein the medium and trace element nutrient solutions contain modulated components, 65-420 ug/L boric acid and 230-1600 ug/L manganese salt, the modulated components contain at least two of 310-690 mg/L calcium salt, 400-1300 mg/L magnesium salt and 40-250 mg/L ferric salt. The present invention can obviously improve yield, appearance quality and leaf tensile force of the wrapper by applying the nutrient solution with specific components in different stage of the wrapper cultivation, respectively, thereby greatly improving the industrial availability of the wrapper raw materials.

The present invention relates to a dual-use solar vortex greenhouse with a clamshell-shaped roof comprising a plurality of multi-paned, paired trapezoidal chutes (1) configured to capture and concentrate solar-heated air. Heated and moistened air flows through vanes (32, 33) into a swirl chamber (27), forming a vortex that spins an electric wind turbine (10) to generate electricity. A cone (2) and stack (16) assembly stabilize the vortex and directs exhaust upward. The interior of the greenhouse (55) supports hydroponic plant cultivation with integrated climate control systems, including shutters and/or orifice closure doors (11,42,35), dampers (23,30,31) misters (34), and radiators (43), which are electronically regulated by a plurality of thermostats (41) including a humidistat, anemometers (41), actuators (24) including a photocell sensor. The structure is modular and latitude-adjustable for maximizing solar capture, and can be prefabricated. The invention integrates renewable energy generation with sustainable food production, providing efficient use of land, water, and solar resources.
