The role of carbon dioxide detectors in greenhouse fruit cultivation.
1, Accurately regulate concentration to meet crop needs
The photosynthesis of plants cannot do without carbon dioxide, and the relatively closed environment of Dapeng is prone to fluctuations in carbon dioxide concentration. When crops have not yet started a large amount of photosynthesis in the early morning, the concentration is higher; As the light intensity increases and crop photosynthesis intensifies, the concentration of carbon dioxide will rapidly decrease. The carbon dioxide detector can monitor the concentration values in the greenhouse in real time. Growers can adjust the demand for carbon dioxide during different growth stages of crops. For example, if cucumbers have an increased demand for carbon dioxide during the fruiting period, they can maintain the concentration in an appropriate range by applying gas fertilizer in a timely manner, providing sufficient "raw materials" for photosynthesis and ensuring the healthy growth of crops.
2, Improve photosynthetic efficiency and promote increased production and income
When the concentration feedback from the carbon dioxide detector is insufficient, growers can significantly improve crop photosynthetic efficiency by supplementing with carbon dioxide. Taking strawberries as an example, after reasonable supplementation of carbon dioxide, the accumulation of sugar in the fruit increases, the fruit becomes larger and sweeter, and the yield can be increased by 15% -30%. Tomatoes develop faster and mature faster in an environment with sufficient carbon dioxide, allowing them to enter the market early and seize the market, bringing higher profits to growers. Adequate carbon dioxide can enhance crop stress resistance, reduce the occurrence of pests and diseases, and lower the cost of pesticide use.
3, Prevent excessive concentration and ensure crop safety
In the cultivation of Dapeng, improper application of gas fertilizer or untimely ventilation can easily lead to excessive concentration of carbon dioxide. Excessive concentration can inhibit crop respiration and affect normal plant growth and development. The carbon dioxide detector can detect abnormal concentration increases in a timely manner, reminding growers to immediately ventilate and remove excess carbon dioxide, maintain the balance of the greenhouse gas environment, and avoid damage to crops.
4, Optimize planting management and achieve scientific decision-making
By long-term use of carbon dioxide detectors, growers can accumulate data on changes in carbon dioxide concentration under different crops, growth stages, and weather conditions. Based on these data, patterns can be summarized and more scientific carbon dioxide replenishment plans and ventilation management strategies can be developed. For example, on cloudy days with weak sunlight, reduce the amount of gas fertilizer used appropriately; In sunny days with high temperatures and strong sunlight, increasing the frequency and amount of supplementation can achieve precise and intelligent planting management, improve resource utilization efficiency, and reduce production costs.
