Advantages and Usage of Micro-Spray Belts

Micro-spray belts, also known as porous pipes, spray tapes, or micro-irrigation pipes, are water-saving irrigation devices used in drip irrigation or micro-spray irrigation. These belts are manufactured by mechanically or laser processing small water outlets on compressible plastic hoses, enabling the formation of a fine rain-like spray when directly laid on the ground. Alternatively, when single or double water outlet spray belts are laid under the plastic film, they create a drip irrigation effect shielded by the film. Our factory currently offers three main categories and dozens of micro-spray belts, capable of meeting various dryland usage requirements and customizable to user specifications.

Advantages of Micro-Spray Belts:

  1. Water Saving: Micro-irrigation reduces deep seepage and surface evaporation, saving approximately 1/3 to 1/2 of water compared to surface irrigation and 15% to 25% compared to spray irrigation.
  2. Energy Efficiency: Operating at low pressure, micro-irrigation systems reduce energy consumption, with working pressures typically ranging from 50 to 150 kPa, lower than those of spray irrigation.
  3. Uniform Irrigation: Precision irrigation ensures effective control of the flow rate of each irrigation device, with irrigation uniformity reaching 80% to 90% across the entire system.
  4. Increased Yield: Micro-irrigation supplies water and fertilizer to crops’ root zones timely and adequately, maintaining soil moisture at optimal levels for nutrient absorption. It also regulates microclimate conditions in fields, promoting optimal growth environments for crops and typically increasing yields by approximately 30% compared to other irrigation methods.
  5. Strong Adaptability to Soil and Terrain: Suitable for both clayey and sandy soils, micro-irrigation systems, being pressure pipeline-based, can be used on flat land as well as in hilly and sloped areas.
  6. Utilization of Brackish Water Resources: Under certain conditions, crops can grow normally and achieve high yields using micro-saline water irrigation. However, in arid and semi-arid regions, freshwater should be used for soil flushing at the end of the irrigation season to prevent soil degradation.
  7. Labor Savings: Micro-irrigation systems eliminate the need for land leveling, trenching, or ridge formation, and can be automated, significantly reducing labor and workload for field irrigation.

Characteristics of Drip Irrigation Belts:

  • Made with labyrinth flow channels and drip holes, our belts are vacuum-molded in one step, ensuring good adhesion and high manufacturing precision.
  • With turbulent flow and multiple outlets, they boast strong anti-clogging capabilities.
  • Designed with labyrinth flow channels for uniform water distribution, achieving a distribution uniformity of over 85%, and can be laid up to 80 meters.
  • Lightweight and easy to install and manage, with low installation costs.


  • Ideal for greenhouse and tunnel crop cultivation, reducing pests and diseases, saving on fertilizers and pesticides, and enhancing economic benefits.
  • Effective for orchard irrigation, improving yields, fruit quality, and weed control.
  • Suitable for a variety of field crops such as cotton, medicinal herbs, watermelons, and field vegetables, enhancing mechanized planting efforts.
  • Drip irrigation belts can be easily laid around mounds and curves, offering convenient operation.
