DEVICE FOR MAGNETIC STIMULATION OF PLANT GROWTH Russian patent published in 2023 - IPC A01G7/04 

FIELD: crop production.

SUBSTANCE: devices for magnetic stimulation of plant growth. The device for magnetic stimulation of plant growth is a frame consisting of a lower, middle and transparent upper shelves, racks, a control unit with measuring instruments, and a magnetic stimulation unit. The magnetic stimulation unit consists of a telescopic electromagnet mounted in a rack. The electromagnet includes a lower coil wound on a lower branch pipe with a lower core inside, and an upper coil wound on an upper branch pipe with an upper core inside. The coils are connected by wires to the control unit, which in turn is connected to the network. The upper branch pipe with a wound coil enters the gap between the core and the lower branch pipe, and is attached to the upper shelf in the upper part. The upper and lower cores are assembled from alternating short and long plates made of electrical steel, the difference in length of which is equal to half the total length of the upper and lower coils, which, as a result, form gaps between the long plates on one side of the core. On the reverse side, the plates of each core are fastened together and attached to the middle and upper shelves, respectively, while the long plates of one core enter the gap of the second core. A square stand with mounting holes is installed on the outer side of the central post, in which conical containers with soil and plants are located in a suspended state. On the lower side of the upper shelf and the upper side of the middle shelf, plates made of electrical steel sheets are located radially relative to the central post so that the bent ends fall into the area of the container with the soil and the plant.

EFFECT: increase in the efficiency of using a magnetic field when stimulating plants.
