How can deta co2 monitor help crops increase yields?
The most commonly used in greenhouses are temperature and humidity sensors, deta co2 monitor, light sensors, and soil nutrient sensors.With the development of modern technology. Agricultural planting is becoming easier. In the past, it was common for agricultural planting to run to the field. Nowadays, agricultural irrigation and fertilization can be easily completed with the help of mobile phones and computers.The development of emerging agricultural technologies. Make farmers gradually get rid of relying on nature and subject to the influence of nature.
Carbon dioxide helps agricultural production
Carbon dioxide is a necessary condition for crop production. Reasonable carbon dioxide concentration is conducive to photosynthesis of crops. In the greenhouse, the carbon dioxide concentration is collected through the deta co2 monitor. The carbon dioxide is supplemented and discharged in time through the control system. Make crops reach the most suitable concentration value.
What is the relationship between carbon dioxide and increased production?
Insufficient carbon dioxide: Vegetables lacking carbon dioxide have dark and dull leaves and poor plant growth. Flowering is late, with fewer female flowers, and more flowers and fruits fall off. The leaves are low and flat, perpendicular to the main branch or drooping, and the leaf surface is uneven. There are many abnormal fruits, 2-3 days late to market, low yield and few high-quality fruits.
Excessive carbon dioxide: The concentration of carbon dioxide is too high. It often causes the leaves of vegetable crops to curl, which affects the normal progress of photosynthesis. It will affect the absorption of oxygen by crops and cannot carry out normal respiratory metabolism.
The concentration of carbon dioxide required by crops is generally 1000 to 1500 ppm. Cucumbers, tomatoes, and zucchini are three common vegetables. In response to this actual situation, carbon dioxide gas experiments were carried out on these three kinds of vegetables, and the effect of increasing production was very significant. The three kinds of vegetables were applied with a carbon dioxide concentration of 1000 mg/kg.
Cucumber yield increased by 465.5 kg per 667 square meters, an increase of 27.1%;
An average increase of 410.7 kilograms per 667 square meters of tomatoes, an increase of 23.6%;
The output of zucchini increased by 373.2 kg per 667 square meters, an increase of 21.9%.
By comparison, we know that after applying carbon dioxide to the greenhouse vegetables. Plant traits were significantly better than those without carbon dioxide application.
In summary, an appropriate concentration of carbon dioxide can promote photosynthesis. But too high (the volume fraction of carbon dioxide in the air exceeds 0.5%-0.6%) will reduce the efficiency of photosynthesis. Moreover, carbon dioxide is heavier than air, and it is easy to accumulate near the ground after a large amount of use. A long time will reduce the oxygen content in the surface soil layer, resulting in weakened root respiration. Thereby affecting the growth and development of the root system. Therefore, installing a carbon dioxide sensor in the greenhouse can ensure that the carbon dioxide concentration is too high or too low to alarm in time.
