Carbon dioxide is an important raw material for photosynthesis and an indispensable substance in the growth of vegetables. Therefore, in greenhouse cultivation, supplemental carbon dioxide has become an important means to increase the quality and yield of greenhouses. However, carbon dioxide gas fertilizer cannot be used blindly. If it is difficult to control the amount and method of use, it may cause damage to the crops and affect the normal growth of vegetables, resulting in reduced production. Therefore, we must do a good job of carbon dioxide gas fertilizer application in greenhouses, you can use carbon dioxide detector to check.
The key two points in the application of carbon dioxide gas fertilizer in greenhouses are the strict control of the amount of carbon dioxide application and the rational arrangement of application time. The appropriate concentration of carbon dioxide can promote photosynthesis, but too high (more than 0.5% -0.6% of the volume fraction of carbon dioxide in the air) will reduce photosynthesis efficiency. Therefore, the use of carbon dioxide detector to detect carbon dioxide content in greenhouses, can accurately know the carbon dioxide content in greenhouses, at the most appropriate time, increase greenhouse gas production for the appropriate amount of greenhouse application, so as to improve the efficiency of photosynthesis of greenhouse crops, increase production The effect of increasing income.
In addition to different greenhouse crops, as well as the different stages of crop growth, the amount of carbon dioxide required to apply is also different, such as from the colonization of the eggplant vegetables to flowering, carbon dioxide demand is small, generally do not need to apply. When vegetables are applied after flowering and fruit setting, this will have a significant effect on reducing flowering and fruiting, increasing fruit setting rate and promoting fruit growth. In order to apply refined carbon dioxide gas fertilizer, it is necessary to first understand the actual carbon dioxide situation in a greenhouse. The carbon dioxide detector is a professional instrument for measuring the carbon dioxide content of greenhouses. In the greenhouse application of carbon dioxide gas fertilizer, the carbon dioxide detector can play a role. Precise control of the effect, effectively improve the application of carbon dioxide gas fertilizer.
