The device has the advantages of low construction cost, low maintenance costand good carbon-rich cultivation effect.

Description

technical field [0001] The invention relates to the technical field of cultivation greenhouse design, in particular to a low-cost carbon-rich closed cultivation device based on the Internet of Things. Background technique [0002] Carbon-enriched cultivation refers to the cultivation of crops under high carbon dioxide concentration environmental conditions. The atmospheric carbon dioxide concentration is about 400ppm, while the suitable carbon dioxide concentration for most crop growth is 1000ppm. Carbon dioxide is the substrate for photosynthesis of crops. Increasing carbon dioxide in the cultivation environment can significantly increase the intensity of photosynthesis, thereby speeding up the growth rate of crops, and at the same time improve the disease resistance and stress resistance of crops themselves, reduce the occurrence of diseases and insect pests, reduce the stomatal conductance, and reduce the crop growth rate. Transpiration consumes water, so in actual produc...

AI Technical Summary

Problems solved by technology

Carbon-enriched cultivation requires a certain closed cultivation environment. At present, this technical measure can only be applied in facility agriculture (greenhouses, sheds, etc.), but the relevant application technology is still blank in the wider open field cultivation. For carbon-rich cultivation, the cost of large-scale construction of greenhouses, sheds and other facilities is too high, and it is obviously not feasible. It is necessary to build a low-cost carbon-rich cultivation closed cultivation technology; The design of the rain requires a large number of skeleton structures, and its construction cost is extremely high
