Why Use Carbon Dioxide Detector

Apart from the need for sunlight and water, photosynthesis also requires sufficient carbon dioxide. The most suitable crop for carbon dioxide concentration is 1‰-1.5‰. The concentration of carbon dioxide in the air is 0.4 ‰. In greenhouses and greenhouses, due to the constant absorption of vegetables, the concentration of carbon dioxide is only 0.1 ‰, which is far from meeting the needs of crops. Therefore, adding carbon dioxide gas fertilizers will become an important measure for increasing production in greenhouses and greenhouses.

Different plants in different climate conditions, the demand for carbon dioxide is different, there is an optimal value and ceiling. If the content of carbon dioxide in the air exceeds the limit, crops will reduce production. Therefore, use an instrument to measure the concentration of carbon dioxide in the air and instruct the application of gas fertilizer so that it reaches its optimum value without exceeding the limit. In general, carbon dioxide gas fertilizer should be used in addition to sunny noon and high temperatures in the shed. In the early morning and early evening, when the shed temperature is low, it must be applied less; In short, it depends on the sunshine, the temperature, and the type of crop. As to how much it is appropriate to apply, it should be measured with a carbon dioxide meter. Otherwise, it can only be estimated by experience, and carbon dioxide is a colorless and odorless gas, it is difficult to grasp, will affect the effect of increasing production.
