Arrow drippers are an important component of drip irrigation systems, suitable for precise irrigation, especially for potted plants, seedlings, vertical greening, and other scenarios. Arrow drippers come in various types, including straight arrow, bent arrow, long arrow, and short arrow, and can be flexibly configured according to different irrigation needs.
Arrow drippers are usually installed onPE pipes (capillaries), and structurally consist of the upper body, lower body, and arrowhead. The installation position of the arrow drippers can be adjusted according to the planting-spacing of crops, greatly improving the flexibility of irrigation. The ingenious design of the arrow dripper features a turbulence flow path on its arrow shaft, which can maintain relatively stable flow even with changes in water pressure. This characteristic allows the arrow drippers, when used in conjunction with pressure-compensating drippers, to double ensure the uniformity and stability of the irrigation system's water output, ensuring that crops receive uniform water supply under different water pressure conditions.
According to different irrigation needs, arrow drippers can be combined in various forms, commonly including single-arrow drippers, double-arrow drippers, and four-arrow drippers. Using a single-arrow dripper is simple: directly connect the arrow shaft with the PE capillary, then insert the pressure-compensating dripper into the punched hole of the capillary, and finally insert the arrow dripper into the soil at the crop's root.
Combining double-arrow or four-arrow drippers requires using small tees or small crosses. First, connect the arrow dripper to the capillary, then connect with the small tee or small cross, and finally connect the pressure-compensating dripper to the capillary, forming a complete arrow dripper irrigation system.
Arrow drippers have significant advantages in water-and-fertilizer integrated irrigation systems. Firstly, they have strong adaptability to water pressure changes and can control a smaller flow rate while ensuring uniform irrigation, greatly improving water-fertilizer utilization rate. Arrow drippers achieve an irrigation uniformity of85% to 95%, ensuring even distribution of water and nutrients to the crop roots, reducing water resource waste.
Arrow drippers are also designed with practicality and durability in mind. Their sockets form a tight connection with the capillary, preventing the arrowhead from easily falling off; the soft capillary is easy to operate and not easily damaged by bending. The small arrow body allows it to be hidden among plants, neither affecting aesthetics nor interfering with planting operations.
Additionally, the water-saving effect of arrow drippers is very significant. Compared to traditional manual irrigation methods, arrow dripper irrigation system can increase water resource utilization efficiency by50% to 70%. This highly efficient water-saving irrigation method not only reduces operating costs but also reduces water evaporation during irrigation, thereby lowering air humidity, reducing the occurrence of diseases and pests, and helping maintain healthy crop growth.
