In the greenhouse strawberry planting, most people are concerned about the temperature and humidity of the greenhouse and the temperature and humidity of the soil, and often ignore the effect of carbon dioxide in the greenhouse on the growth of strawberries. In fact, the concentration of carbon dioxide is important in the growth of strawberries. Energy conversion process - photosynthesis, so scientific determination of carbon dioxide concentration in the greenhouse, and reasonable greenhouse ventilation, is conducive to strawberry yield and efficiency, and the determination of carbon dioxide concentration in the greenhouse, there is a very simple measurement method, that is to use Carbon dioxide detector . In general, the concentration of carbon dioxide in the air is very low, only 200 to 300 microliters / liter. In the greenhouse, because it is in a closed environment, the change of carbon dioxide concentration is more obvious than that of terrestrial cultivation. The carbon dioxide detector has been used to determine the concentration of carbon dioxide in the greenhouse. The content of carbon dioxide in the greenhouse is different in one day. After that, the concentration of carbon dioxide in the shed gradually increased, reaching the highest before sunrise, rising to 500 microliters per liter; after more than one hour of sunrise, the concentration of carbon dioxide gradually decreased, and dropped to 100 microliters per liter at 9 am, although it was ventilated. The concentration of carbon dioxide in the shed has rebounded, but it is still below 300 microliters/liter. The low concentration of carbon dioxide in the greenhouse is not conducive to the growth and development of strawberries, especially affecting the normal photosynthesis of strawberries. Appropriately increasing the concentration of carbon dioxide in the greenhouse can make the leaves of strawberries thicker, the leaves are darker green, the fruits are enlarged, and the maturity is advanced. Increase production by 15% to 20%. Therefore, in order to obtain high yields and high yields, the determination of carbon dioxide concentration in strawberry greenhouses has also become a formal and necessary measurement project. The use of a carbon dioxide detector to detect the concentration of carbon dioxide in a strawberry greenhouse is simple and efficient. It can better apply the test data for scientific research, and can also guide the planting management of the greenhouse to create suitable environmental conditions for greenhouse strawberry growth.
