CO2 enrichment for greenhouse plant
We usually have the following three forms to increase carbon dioxide to 1000-1500ppm for plant rooms
1. Use liquid carbon dioxide: This is supplied in high-pressure bottles of 35 kg each. To use, open the bottle and release the carbon dioxide.Liuqid Co2 can be converted into gasesous, by reducing the pressure and is then released inside the grenshouse; Such as through inflatable polyethylene tubing with holes along its length
2. Use solid carbon dioxide: solid carbon dioxide is also called “dry ice”, according to the needs of the shed, dry ice wrapped in paper or placed in water, so that it is slowly released.
3. Burn petroleum or propane, etc., and burn these substances outside the shed to draw carbon dioxide into the shed. This method should prevent toxic gases such as sulphite from harming the crops
Although carbon dioxide is an essential substance for plant growth, too much carbon dioxide in a closed shed will cause a greenhouse effect and the temperature will be too high, which may also affect the growth of vegetables. In addition, the production of carbon dioxide in a closed shed, especially by artificial methods, sometimes generates carbon monoxide due to a lack of oxygen, which may cause people to be poisoned, and every year there are Every year, people die from carbon monoxide poisoning, and this is something we must be aware of when working in greenhouses.
