Different plants have different requirements for CO2 under different climatic conditions. If the concentration of CO2 exceeds the limit, crops will be reduced. Therefore, the instrument must monitor and control the concentration of CO2 in the air and make it reach the optimum value. At present, the existing carbon dioxide detectors at home and abroad are expensive and are not suitable for use by Chinese farmers. To this end, as soon as possible to develop cheap carbon dioxide detector to solve the urgent needs of vegetable production.
The stronger the sunlight, the higher the humidity, the stronger the photosynthesis of the plant. So the more CO2 gas is needed. Therefore, when the sun is strong at noon on a sunny day, the plastic stays within the barrel. The CO2 gas fertilizer should be applied at a concentration of 1,000 to 1,500 ppm. In the morning or in the afternoon, the sun is weak. When the temperature is low in the big urn, CO2 gas fertilizer should be less applied. The concentration should be between 500 and 800 ppm. Cloudy or rainy days. No sunshine. CO2 gas fertilizer should not be added. According to the demonstration results of the CO2 side-viewer across the country in the past two years, the effect of vegetable production increases significantly. Compared with the control amnesty, the average increase of 20% per mu. At present, CO2 detectors have been widely used in provinces and cities such as Jilin, Liaoning, Beijing, Hebei, Shandong, and Henan.
Photosynthesis is very important for the yield increase of crops because more than 95% of crop yields depend on it. That is, plants use sunlight to synthesize CO2 and water into carbohydrates. However, the CO2 content in the air is too low at only 330 ppm. Therefore, the application of C6z gas in greenhouses or plastic bottles can greatly increase the production of vegetables. For the determination of carbon dioxide content in greenhouses, carbon dioxide detectors can generally be selected for detection.
