CONTROL METHOD OF FORMING HARVEST IN GREENHOUSE AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC A01G7/00 A01G9/24 

FIELD: agriculture.

SUBSTANCE: method comprises growing plants in the optimisation biotechnological full-scale model with its placement in the greenhouse with plants of the same culture and breed. At that the terms of planting crops in the greenhouse are shifted by a time interval relating to the terms of planting crops in the optimisation biotechnological full-scale model, depending on the culture and breed of plants, consisting not more than 10% of the ripening period. The crop development process in the greenhouse is monitored by a productive biotechnological full-scale model with terms of planting crops similar to the terms of planting in the greenhouse. The crops in the greenhouse, the optimisation and productive biotechnological full-scale models are provided with a system of microclimate, irrigation and mineral nutrition of plants, common for all areas of the greenhouse, and equal conditions are provided on natural solar insolation all three areas. Areas of the main crop of the greenhouse and the productive biotechnological full-scale model are irradiated from the common system of irradiation, and the area of the optimisation biotechnological full-scale model - from the local system of irradiation. The parameters of microclimate, irrigation and mineral nutrition of plants are taken as non-optimised, and the parameters of irradiation of plants - as optimised. The optimisation of control actions for plants in the optimisation biotechnological full-scale model is carried out with the formation of an optimised program of development of plants, which is transferred with the time shift to the greenhouse crop, and the productive biotechnological full-scale model. The system comprises a greenhouse with plants of one crop and breed, optimisation biotechnological full-scale model, the means of measuring the physiological processes of plants in the optimisation biotechnological full-scale model, the means of measuring the parameters of irradiation of plants in the optimisation biotechnological full-scale model, the first comparison device, and the device of optimisation. Additionally it comprises a productive biotechnological full-scale model, the means of measuring physiological processes of plants, and the means of measuring parameters of irradiation of plants in the production biotechnological full-scale model, a storage device of programs of plant growth, a program setpoint of plant growth, the first device of formation of the program of plant growth, the first device of plant irradiation mode control, the first system of plant irradiation, the time synchronisation device, the device of the time delay formation, the second device of formation of the program of plant growth, the second comparison device, the second device of plant irradiation mode control, the second system of plant irradiation, the system of controlling the microclimate of the greenhouse.

EFFECT: increased productivity, reduction of period of growing production, reduction of complexity and labour intensity of the process of controlling the formation of the crop under conditions of protected ground.
