As an efficient and precise temperature control technology, heating cable plays a key role in modern agricultural vegetable and fruit greenhouse insulation. Heating cable through the nickel-chromium alloy and other resistive materials energized to produce the Joule effect, the electrical energy into heat, the working temperature is stable at 40-60 degrees, which through direct heating of the soil or regulation of the environmental temperature, to provide stable and controllable heat support for crop growth, the specific functions are reflected in the following aspects:
I. Precise regulation of temperature environment
Stabilization of soil temperature The
heating cable is buried in the soil, through direct heating of the root zone, so that the soil temperature is evenly maintained in the appropriate zone (usually 15-25 ℃). This bottom-up heating method can avoid the temperature fluctuation caused by traditional air heating, especially suitable for early spring nursery in cold areas, which can shorten the time of seedling emergence by more than 30%
Optimize the greenhouse environment
Heating cables can be laid at the bottom or wall of the greenhouse to provide auxiliary heating to the air and ensure the overall temperature in the shed is constant. The overall temperature of the greenhouse is constant. For example, by setting the threshold value through the thermostat, the system can automatically start and stop, realizing the precise control of day and night temperature difference of ≤3℃.
Second, promote crop growth and quality enhancement
Root development and nutrient absorption
Stable ground temperature can accelerate plant root growth and enhance nutrient absorption efficiency. Experiments have shown that in greenhouses using heating cables, the root density of seedlings is increased by 20%-30% compared with the traditional way, and the plant resistance is significantly enhanced.
Shorten the growth cycle
The radiant heat released by heating cables can penetrate plant tissues and promote photosynthesis and metabolic rate. For example, in vegetable nursery, the growth cycle of seedlings is shortened, and indicators such as plant height and leaf area are superior to those of conventional methods.
Third, energy saving, environmental protection and sustainability
Energy Efficiency Advantage
The heating cable is driven by electric energy, and the thermal conversion efficiency can reach over 95%, which is 30%-40% more energy efficient than coal-fired boilers. At the same time, when combined with the photovoltaic power generation system, it can further reduce the cost of energy consumption, realizing the green cycle of “self-generation and self-consumption, and the surplus power on the Internet”.
Reduce carbon emissions
By replacing traditional fossil fuel heating, a single standard greenhouse can reduce carbon dioxide emissions by about 2.5 tons per year, which is in line with the demand for low-carbon transformation of agriculture.
Flexible Installation and Convenient Operation and Maintenance
Adaptive Design
The heating cable can be customized according to the structure of the greenhouse to support horizontal buried, vertical hanging or wall embedded and other installation methods, suitable for different crops and planting scenarios.
Intelligent Control and Low Maintenance
Combined with IoT sensors, the system can monitor parameters such as soil humidity and ambient temperature in real time, and remotely regulate and control them through the cell phone terminal to reduce the cost of manual management.
Through multi-dimensional technology integration, heating cable has become an important infrastructure for modern agricultural greenhouses to realize efficient and green production. Its precise temperature control, energy saving and intelligent management characteristics, for the modernization of agriculture provides a reliable technical support.
