A snow melting system for greenhouse comprises sensors for measuring an accumulation of snow on or at the greenhouse. A snow melting processor unit comprises an accumulation rate calculator for calculating an accumulation rate of the snow from the measured accumulation, and a heating prioritizer for actuating at least one of at least two different heating systems of the greenhouse as a function of at least the accumulation rate. A rooftop greenhouse system comprises a greenhouse adapted to be mounted to a rooftop surface. Two or more different heating systems mounted to the greenhouse to heat a roof of the greenhouse, and controlled by the snow melting system.

An installation evaluation apparatus 10 for a greenhouse includes an input device 11, an insolation evaluation unit 12, and a presentation device 13. The input device 11 is configured to receive input of position information relating to a planned location for installing the greenhouse. The insolation evaluation unit 12 is configured to determine variation, according to the date and time, in an insolation amount in the planned location by performing a computer simulation using the position information input into the input device 11. The presentation device 13 is configured to visualize and present the variation in the insolation amount according to the date and time, determined by the insolation evaluation unit 12.
摘要:
A greenhouse growing environment has a distributed control system for selecting, monitoring, and administering hydroponic nutrient solution mixtures that are tailored to crop varieties of the greenhouse. The crop varieties are preselected based on location characteristics of the greenhouse and analysis results of source water. The analysis results indicate a nutrient composition of the source water. A predefined nutrient formulation is then automatically combined with the source water by a nutrient dispensing subsystem, to achieve a desired nutrient solution mixture that is applied to a hydroponic bay. A computational system automatically monitors the state of a hydroponic environment and directs input modules as programmed, in order to increase plant growth, plant quality, and volume of plant yield.

There are provided a cultivation control system, a cultivation control program, and a cultivation control method that can independently set growth conditions in a plurality of divided cultivation spaces and that can perform control by changing growth environments in the individual cultivation spaces. In a cultivation apparatus 300, each of the internal environments of a plurality of shielded spaces is shielded from the internal environments of the shielded spaces adjacent thereto and from an external environment of the cultivation apparatus 300. A portable communication communication terminal 200 performs remote control of environment control apparatuses 350a to 350f such that at least one of the internal environments of the plurality of shielded spaces is independently controlled.
摘要:
The invention relates to a method for controlling the atmosphere in a closable space filled with agricultural or horticultural products. The method comprises directly detecting the respiration of the agricultural or horticultural products and adjusting an oxygen content, a carbon dioxide content and/or a nitrogen content in the space subject to the detected respiration. The respiration is detected here periodically, in each case for a determined time, and the space is sealed off from external influences during detection of the respiration. A very good control is achieved by taking the actual respiration as starting point, and a highly reliable detection forms the basis of this control when the detection is performed periodically for some time in a completely isolated atmosphere. The invention also relates to an installation for performing the method, and to a closable space provided with such an installation.

An embodiment includes an enclosure having a nutrient bed for retaining and providing nutrients to plants grown therein. An adjustment mechanism provided for adjusting the level of one or more environmental variables therein so as to at least partially simulate the growing conditions found at a specific altitude. Exemplary environmental variables include water levels, broad-spectrum light intensity, UV light intensity, pH, nutrients, air temperature, soil temperature, atmospheric carbon dioxide, atmospheric oxygen, atmospheric pressure and combinations thereof. The adjustment mechanism may include one or more broad-spectrum/full spectrum lights, UV generating lights, skylights, vacuum/pressure pumps, hypoxicators, oxygen generators, carbon dioxide regulators, heaters, air conditioning units and so forth.
摘要:
A crop protection device that is designed to cover a number of citrus fruit trees during periods of cold weather. The device is a heated canopy system that is made from a lightweight, high strength fabric that is supported by a number of ground-mounted frame members. The ends of the fabric are attached to one another by a drawstring, which is wound through a series of eyelets on the fabric. The device also includes a heater and blower unit that continuously blows hot air within the confines of the fabric after the fabric has been mounted over at least one citrus plant.
