METHOD FOR PHOTOELECTRIC STIMULATION OF PLANT GROWTH AND DEVELOPMENT Russian patent published in 2024 - IPC A01G7/04 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely to the means of plant vital activity stimulation. Method comprises exposing a plant to a pulsed light flux of a certain radiation spectrum with given parameters of the pulse sequence, required radiation spectrum of which is obtained by superimposing radiations generated by sources of blue, green and red colours, in different proportions of intensity of their radiation with possibility of independent adjustment of parameters of each of said light sources, along with which the density of the photosynthetic photon flux of the irradiated plant is measured. Synchronously with irradiation of the ground part of the plant with pulses of light flux, the root part of the plant is exposed to pulses of electric current flowing through the soil. Shape of the pulses of both the light flux and the electric current is set in the form of a trapezoid, thus providing the possibility of independent control of the parameters of the pulse sequence of both the light flux and the electric current. Signal from the output of the density sensor of the photosynthetic photon flux is used for automatic control of the intensity of the light flux, and the signal from the output of the current sensor is used for automatic control of the level of electric current. Along with this, the effect on the plant with the light flux and the effect on the plant with electric current are synchronized with the plant watering schedule so that before each watering the plant perceives the synchronous effect of the light flux pulse and the electric current pulse, while during the whole watering period the effect of light flux and electric current on the plant was minimal. General control of the process of photoelectric stimulation of plant growth is carried out by the signal from the output of the sensor for measuring intensity of photosynthesis.

EFFECT: method provides higher intensity of plant photosynthesis with low power consumption of equipment used for plant cultivation.
