Drip irrigation tape is a water-saving, yield-enhancing irrigation technique specifically developed for greenhouse and polytunnel production. It is a form of localized irrigation that keeps only the immediate soil surface moist, with no standing water and reduced water evaporation. By using dual-row drip tape laid directly on the crop beds, this method provides an optimal growing environment for crops inside the greenhouse. The following section introduces this new dual-row soft-tube drip irrigation technique:

Irrigation method: Drip irrigation delivers water in small, uniform, and slow droplets directly to the soil near the plant roots through emitters installed on capillary tubing. Thanks to the capillary action of the soil, the water infiltrates and spreads throughout the soil profile, where it is absorbed and utilized by the plant roots. This maintains the soil in a non-saturated state, keeping it loose and well-aerated, which promotes healthy plant growth. The principle for soft-tube drip irrigation is frequent, light watering, with each application ranging from 7 to 15 cubic meters per mu.

      Drip irrigation tape manufacturer Specific procedures for drip irrigation tubing and flexible tape: First, when irrigating with plain water, open the suction valve on the fertilizer injector, then fully open the valve, and finally connect to a pressurized water source to begin irrigation. Second, when applying fertilizer solution, open the valve, turn on the suction switch of the fertilizer injector, secure the filter at the bottom of the fertilizer solution tank, and connect to the water supply to commence fertilization. If fertilization is temporarily halted, reopen the suction switch and keep the valve open to continue irrigation, thereby flushing out any residual fertilizer remaining in the tubing.

Precautions for drip irrigation tubing and flexible tape:

(1) Install a drip irrigation system, ensuring that the controlled area for each main lateral does not exceed approximately 0.5 mu, and that the ground surface in contact with each drip hose is level to guarantee smooth water flow.
(2) The emitters in drip irrigation tape are typically laid with the emitter openings facing upward and used in conjunction with plastic mulch; if plastic mulch is not used, the tape may be laid with the emitter openings facing downward.
(3) Use clean water sources; the water must not contain suspended particles larger than 0.8 mm. If such particles are present, a mesh filter must be installed to purify the water. When using tap water or well water, filtration is usually not required.
(4) During installation and field operations, take care to avoid scratching or puncturing the drip irrigation tape or main pipe.
(5) After fertilization, continue to flush the holes with clean water for a period of time to prevent chemical residues from accumulating at the hole openings and causing blockage.
(6) To prevent sediment and other impurities from accumulating inside the pipes and causing blockages, sequentially open the ends of the drip irrigation tapes and main lines to increase flow and flush out the system.
(7) During crop rotation, dismantle the equipment and store it properly in a cool, shaded area.
