Pressure compensation drip irrigation tape, through its unique design and functions, is particularly suitable for special application scenarios such as complex terrain, high-frequency short-duration irrigation, subsurface drip irrigation, greenhouse soilless and substrate cultivation.
Special Applications of Pressure Compensation Drip Irrigation Tape
Pressure compensation drip irrigation tape is an efficient water-saving irrigation technology, particularly suitable for the following special application scenarios:
1. Complex Terrain and Long-Distance Laying:
• Uniformity: Within the pressure compensation working range, the flow rate of any drip head in the irrigation area is consistent, unaffected by the length of laying or differences in terrain elevation, ensuring uniform irrigation.
• Drip Prevention: After the system is shut down, the water pressure inside the pipe is 0.01MPa-0.03MPa, the drip head stops dripping, but the pipe remains filled with water, ensuring that all drip heads at the front and rear ends start dripping immediately and simultaneously when the system is restarted. This is particularly suitable for crops that require high-frequency, short-duration irrigation (usually measured in seconds per irrigation).
2. High-Frequency, Short-Duration Irrigation:
• Drip Prevention Function: After the system is shut down, the water pressure inside the pipe is 0.01MPa-0.03MPa, the drip head stops dripping, but the pipe remains filled with water, ensuring that all drip heads at the front and rear ends start dripping immediately and simultaneously when the system is restarted. This is particularly suitable for crops that require high-frequency, short-duration irrigation (usually measured in seconds per irrigation).
3. Subsurface Drip Irrigation:
• No Surface Water Evaporation Loss: Subsurface drip irrigation eliminates the evaporation loss of surface water, making it more water-saving than surface drip irrigation tubes (tapes).
• Long-Term Use: Subsurface drip irrigation can be used long-term, eliminating the need to install and lay out the drip irrigation system every season, reducing construction costs. It also avoids potential damage to PE pipes, fittings, and pressure compensation drip heads due to human or mechanical factors.
• Plant Nutrient Optimization: The nutrients required by plants enter the pressure compensation drip head irrigation system through fertilizer tanks, fertilizer valves, or Venturi fertilizer injectors in the irrigation system, and are then directly applied to the roots of the crops.
• Reduced Weed Growth: Subsurface drip irrigation keeps the soil surface dry, reducing weed growth.
• Reduced Pest and Disease: Pressure compensation drip head irrigation reduces pests and diseases caused by moisture near the crops.
4. Greenhouse Soilless and Substrate Cultivation:
• Wide Application Range: Suitable for greenhouse soilless cultivation, substrate blueberries, substrate tomatoes, etc., for the irrigation of vegetables, fruit trees, medicinal materials, seedlings, and other economic crops, meeting the precise irrigation requirements of high-end facility agriculture, especially suitable for hilly and mountainous areas with large elevation differences.
• Multiple Flow Rates Available: Multiple flow rates available (2, 4, 8L/h), suitable for different types of crops, with a wide range of applications.
5. Large Areas, Steep or Undulating Mountainous and Hilly Areas:
• Wide Pressure Compensation Range: A wide pressure compensation range (0.05~0.4MPa), providing stronger applicability.
• Ultra-Low Compensation Function Activation Pressure: Ultra-low compensation function activation pressure, more energy-efficient.
• Self-Flushing Structural Design: Self-flushing structural design, with superior anti-clogging performance.
• Precision Manufactured Pressure Compensation Membrane: Precision manufactured pressure compensation membrane, providing more stable compensation performance.
Summary
Pressure compensation drip irrigation tape, through its unique design and functions, is particularly suitable for special application scenarios such as complex terrain, high-frequency short-duration irrigation, subsurface drip irrigation, greenhouse soilless and substrate cultivation. Its advantages in ensuring uniform irrigation, reducing water waste, improving anti-clogging performance, and adaptability make it an indispensable technical means in modern agricultural irrigation.
