Greenhouse |
Amid the trend toward sustainable agriculture, traditional farming is transitioning to a more efficient and eco-friendly smart agriculture model. Greenhouse cultivation, a key technique, relies on maintaining stable indoor environments to meet crops' optimal growing conditions. By transmitting greenhouse data to smart agriculture systems in real-time through transmitters, environmental conditions can be precisely monitored and adjusted, enhancing crop quality and yield while promoting environmental sustainability.
After successful tissue culture propagation, seedlings are transferred to greenhouses for further growth and development. Thus, environmental monitoring in greenhouses is equally crucial.。
Flowers are high-value crops. In such a highly competitive global market, precise environmental management is essential. Precisely controlling greenhouse temperatures can induce flowering, dormancy, vernalization, and stem growth regulation. This level of control contributes to better flower growth management, enhancing their value, quality, and market competitiveness.
Temperature and Humidity Monitoring
Temperature and humidity transmitters monitor the conditions inside the greenhouse. By using transmitter data, ventilation and smart environmental control systems can be adjusted to ensure that the greenhouse temperature remains within the optimal range. This prevents extreme temperatures from affecting crop growth and creates the ideal environment for improving yield and quality.Airflow and Air Velocity Monitoring
Good ventilation is critical for crop growth. Airflow and air velocity transmitters precisely control the indoor environment to achieve the following:- Lower air temperature: Effectively expel hot air, maintaining a suitable growth temperature.
- Replenish CO2: Introduce outdoor air with approximately 380 ppm of CO2, preventing indoor levels from dropping too low and promoting photosynthesis.
-
Reduce relative humidity: Minimize water condensation on leaves, thereby reducing the risk of disease.
Indoor Carbon Dioxide Concentration
Plants require sufficient carbon dioxide for photosynthesis during their growth. Adequate CO2 supply not only promotes crop growth but also significantly reduces water irrigation needs. Furthermore, a sufficient supply of CO2 can dramatically increase production efficiency, shorten production time, and support more efficient agricultural production.
Mushroom Grow Room |
The growing conditions for mushroom cultivation include the right temperature, humidity, adequate light, and fresh air. These factors directly affect the growth rate and quality of mushrooms. Only when these conditions are balanced can mushrooms grow healthily and yield well. Notably, different types of mushrooms require different temperature, humidity, and air quality levels at various growth stages.
According to the Ministry of Agriculture, for king oyster mushroom, the CO2 concentration should be kept below 1000ppm during the germination phase, below 2000ppm during the growth phase, and stabilized around 1700ppm during the fruiting phase. The ideal fruiting temperature for king oyster mushroom is 16-18°C, with some farms lowering it to 14°C to increase yield.
Before entering the mushroom grow room for cultivating, growing bags are first prepared. During this process, temperature transmitters monitor the sterilization temperature in the autoclave, ensuring precise sterilization conditions and reducing subsequent contamination risks. The growing bags are then transferred to the cooling room for inoculation.
The cooling room must maintain positive pressure using sterile, dust-free air filtration systems to prevent external spore contamination. Differential Pressure Transmitters are used to monitor and maintain positive pressure indoors.
Tissue Culture Lab |
Tissue culture labs lead a more professional production model in modern biotechnology and scientific research. They allow for rapid asexual propagation of plants and cells while maintaining genetic consistency, making them critical for breeding and preserving high-quality species. Tissue culture is especially suited for producing high-value plants (such as medicinal and ornamental plants) and studying specific cell lines. Additionally, tissue culture helps detect and control viral diseases and promotes genetic modification.
In the environment of a plant tissue culture lab, precise control of temperature, humidity, carbon dioxide concentration, and airflow can effectively prevent cross-contamination by bacteria and reduce the risk of mold. Additionally, adequate carbon dioxide supply promotes healthy plant growth, further enhancing the cultivation outcomes.
Laminar flow cabinets provide a contamination-free working environment, allowing researchers to perform inoculations and cultures under safe conditions. These cabinets use high-efficiency HEPA filters to purify the air from microorganisms and particles, ensuring that the air entering the culture area is clean. By using airflow and air velocity transmitters, the laminar flow cabinets can maintain stable and uniform airflow, effectively preventing external contaminants from entering, thereby providing ideal conditions for the cultivation process.
Good management of these environmental factors not only ensures the stability of the cultivation process but also improves both yield and quality, which is crucial for breeding and preserving superior plant varieties. Using laminar flow cabinets for tissue culture allows you to maintain high standards in your experimental environment while exploring the mysteries of plant growth, ensuring that every step is conducted under optimal conditions.
