A positioning device for a plant container having a lip. The positioning device has an extension arm with a hook rigidly connected at one end and a handle rigidly connected at the other end. The positioning device is utilized to move a plant container by engaging the hook with the plant container's lip and then dragging the plant container to a predetermined position. In a preferred embodiment the plant container is a nursery pot.

A device for spreading liquid and/or solid active agents comprises a carrier vehicle, at least one pivotable boom, and sensors for detecting an angular velocity and/or an angular position of the boom. A control unit processes output signals of the sensors to control signals for an actuator to adjust the boom. The actuator produces an actuating connection between the carrier vehicle and the pivotable boom, and has one active pressure side, which is engageable by fluidic actuating pressure, for each of the two adjustment directions of the boom. An approximately equal pressure prevails on the active pressure sides of two actuators operating in opposition or of a double-acting actuator, respectively, when the boom is stationary or moves only slightly in relation to the carrier vehicle. A defined differential pressure is adjustable between the active pressure sides of the two actuators or of a double-acting actuator, when the boom is shifted.

The present invention relates to a method for determining a growth status of a plant comprising chlorophyll, the method comprising the steps of: illuminating the plant (102) with input light including a light intensity modulation component (205, 206, 207, 208); detecting light emitted from the plant; determining (S702) an offset light intensity (204) surrounding the plant, the offset light intensity being a static component of the input light; determining (S718) a phase and a gain between the input light and the detected light, determining (S720) a growth status of the plant based on a predetermined relationship between input light and detected light, and on the phase and the gain. The invention also relates to a corresponding system and to a computer program product.

A shield for protecting a plant having; a stem having an upper end and a lower end; a first plurality of sticks having a proximal end and a distal end; and a pad associated with the upper end of the stem, the pad having a second plurality of holes distributed all around the pad and oriented at various angles in relation to a horizontal plane, the holes being configured for removably receiving the proximal ends of the entire first plurality of sticks or a portion thereof and securing the same therein through friction-based insertion; the second plurality of holes distribution and orientation allowing the formation of a support structure for a protective cover in which the entire first plurality of sticks or a portion thereof extends in a circular arrangement above the plant at an angle conforming to the shape or size of the plant.

A fluctuation belt ecological slope protection system that responds to hydrological variation includes a runoff treatment system and an ecological floating island system. The runoff treatment system includes a grass planting side ditch and a water accumulation pit-pond. The ecological floating island system includes an ecological floating island and an ecological gabion base. The ecological floating island includes a flexible substrate, and aquatic plants. The ecological gabion base is positioned below the ecological floating island. The ecological protection system is suitable for a fluctuation belt and consists of a runoff treatment system and a separable ecological floating island system. Rain water on bank slope is purified and collected as wet soil is stabilized, the protection system responds to backwater water level variation in fluctuation belt, providing growing space for plants, organisms, and fish, following variation in water level, enriching the ecological environment of the fluctuation belt, and improving scenic effect.

A light trolley system for vertical-plane growing that maximizes the coverage area, quality of light, and useable growing area is provided. The light trolley system comprises a support structure and a first C rail secured to the support structure. The first C rail has a first end and a second end. A first brace is mounted to the first C rail and a first light trolley secured to the first brace. The first light trolley has at least one bar light mounted within a light manifold. The first brace supports and stabilizes the first light trolley. The combined first brace and first light trolley is moveable along the first C rail between the first end and the second end of the first C rail allowing the first light trolley to be moved to various locations increasing labor efficiency in the growing area.

A system for growing plants includes an elevated track circuit comprising two straight track sections and two arcuate track sections, with the straight track sections each including a cavity. A plurality of wheeled trolleys that each include a wheel configured to roll within the cavities and each include a shaft extending downwardly form the wheel. A drive system is configured to move the wheeled trolleys along the track circuit with the wheeled trolleys connected together by a cable, and with the shafts of the trolleys configured to support plants coupled thereto to selectively move the plants along the track circuit. Uses of the system include for growing produce of vine plants in a lean-and-lower manner, or transporting hanging plants through an irrigation device of the system.
