In recent years, the greenhouse has developed rapidly. It has not only been used in vegetable cultivation, but also gradually expanded to the cultivation of precious Chinese medicinal materials and fine fruits. And we know that the greenhouse is a closed microclimate space, and the soil environment and atmospheric environment have a great influence on the growth of plants. In order to maintain the appropriate environmental conditions, in the greenhouse cultivation, we need to use carbon dioxide detectors and other testing instruments to Strengthen the detection and management of the soil environment and the atmospheric environment, ensure the safety of greenhouse greenhouse cultivation, improve the management level, and increase the profit of cultivation.
In the management of the atmospheric environment of greenhouses, carbon dioxide concentration is an environmental factor that cannot be ignored. In addition to sunlight and water, photosynthesis also requires sufficient carbon dioxide. Generally speaking, the carbon dioxide concentration suitable for crop growth is 1‰-1.5‰, and the carbon dioxide concentration in the air is 0.4‰. In greenhouses, because crops constantly consume carbon dioxide due to photosynthesis, the carbon dioxide concentration in the greenhouse will often be insufficient. If it can not be found in time, and it can be supplemented by ventilation, or if carbon dioxide fertilizer is added, it will limit plant growth. , Affecting yield quality. The carbon dioxide detector is a professional instrument for measuring the concentration of carbon dioxide. The application of this instrument in the management of the atmospheric environment of greenhouses can help managers to timely understand the changes in the concentration of carbon dioxide in the greenhouses, avoid risks, and improve the degree of refinement of the management of the atmospheric environment , Optimizing the environmental conditions of crop growth and promoting greenhouse planting to increase production and efficiency.
The carbon dioxide detector is a relatively common gas concentration detector. The instrument is widely used in animal husbandry, industry, public places, agriculture and many other fields. In the agricultural field, under normal circumstances, the default range of the carbon dioxide detector is 0-5000ppm. The modern application of the carbon dioxide detector uses a new infrared verification technology to measure carbon dioxide concentration. The response is quick and sensitive, avoiding the short life and long time of the traditional electrochemical sensor. The drift problem is widely used in agricultural greenhouses, flower cultivation, edible mushroom cultivation and other occasions that require carbon dioxide monitoring.
