Abstract

The invention belongs to the technical field of planting industry, and discloses an automatic adjusting device and a method for concentration of CO2 in a greenhouse environment. The device comprises a CO2 gas control module, wherein an input end of the CO2 gas control module is respectively connected with a light intensity sensor and a CO2 concentration sensor; an output end of the CO2 gas control module is connected with a CO2 gas generating module; the light intensity sensor is used for collecting light intensity of the greenhouse environment; the CO2 concentration sensor is used for detecting CO2 concentration in the greenhouse environment; and the CO2 gas control module controls the CO2 gas generating module to discharge CO2 gas according to the light intensity and the CO2 concentration. According to the technical scheme of the invention, the feeding quantity of CO2 required by plants can be controlled accurately, the structure is simple, and the implementation is easy.

Description

technical field [0001] The invention belongs to the technical field of planting, and more specifically, relates to a CO 2 Concentration automatic adjustment device and adjustment method. Background technique [0002] In greenhouses, greenhouses and closed plant factories, etc., apply CO 2 Air fertilizer is an effective way to increase yield. Under certain conditions, with CO 2 As the concentration increases, photosynthesis increases. CO at maximum photosynthetic rate 2 Concentration is the saturation point when CO 2 If the concentration exceeds the saturation point and is too high, it will cause abnormal growth of crops, chlorosis and yellowing of leaves, curling deformity or necrosis, etc. [0003] In the process of cultivation, people hope to produce CO in reasonable demand 2 gas, and can automatically adjust CO according to the results of environmental detection 2 Give air volume. Manufacture of CO by physical or chemical methods 2 , the method of open-loop cont...
