METHOD FOR CONTROLLING AND REGULATING OF PLANT GROWING PROCESS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2006 - IPC A01G7/00 A01G9/24 

FIELD: agriculture, in particular, commercial plant growing.

SUBSTANCE: method involves determining radiation energy absorbed by plants, said energy being used during photosynthesis process and corresponding to average spectral sensitivity of the given kind of plant; growing plant of the given kind by defining design value of total exoergy, with optical radiation wavelength values being taken into consideration; controlling during growing process actual resulting exoergy; ceasing plant growing process when actual resulting exoergy reaches said design value of total exoergy. Apparatus has photosynthesis irradiance sensor, plant kind setter, comparator, unit for calculating design value of total exoergy, actual resulting exoergy indicator, total exoergy design value setter, signaling unit, and controlled switch. Output of photosynthesis irradiance sensor is connected to first input of unit for calculating design value of total exoergy, whose output is connected to first control input of comparator and to input of actual resulting exoergy indicator. Plant kind setter is connected via total exoergy design value setter to second input of comparator, to output of which comparator are connected second input of total exoergy design value calculating unit and inputs of signaling unit and controlled switch. Apparatus is further provided with amplifier whose input defines first input of total exoergy design value calculating unit, and whose output is switched to first input of integrator. Output of said integrator is connected via peak detector and multiplication unit to output of total exoergy design value calculating unit. Connection of zeroing inputs of integrator and peak detector defines second input of total exoergy design value calculating unit.

EFFECT: increased efficiency and reduced operating costs for growing of farm plants.
