Is it correct to introduce carbon dioxide into the greenhouse to increase photosynthesis?
Thread Content
I heard that carbon dioxide is introduced into greenhouses to increase photosynthesis, right? Is the food produced in this way beneficial to health? Is this approach advisable, and how effective is it actually?
When the lighting is suitable but ventilation in the greenhouse is poor, increasing the level of carbon dioxide appropriately can help improve photosynthesis, with very good results
This is relative; when there is sufficient light and an appropriate amount of carbon dioxide is supplied, photosynthesis can be enhanced, and the increase in yield depends on the intensity and duration of the light. Generally, the improvement is around 30%-40%； When there is insufficient light, introducing carbon dioxide has little effect; on the contrary, it is harmful to plant growth.
It has a significant effect, as the carbon dioxide level in the atmosphere is very low. Crops require NPK, and water supply can be controlled artificially; however, the carbon dioxide level in the atmosphere cannot be controlled... Therefore, introducing carbon dioxide leads to a notable increase in yield...... :)
This is the principle behind gas fertilizer: lol
