Drip Irrigation Tape Introduction

1. Overview of Drip Irrigation

Drip irrigation is a precise irrigation method that utilizes a low-pressure pipeline system to deliver water directly to the field. Water is slowly and evenly dripped into the soil near the crop root zone through emitters, orifices, or drip tapes installed on the capillary tubes. This maintains optimal soil moisture in the root zone, ensuring favorable conditions for water, nutrients, air, heat, and microbial activity, thereby creating an ideal environment for high and stable crop yields.

Drip tapes are categorized into:

Inlaid Drip Tape

Embedded Cylindrical Drip Pipe

Labyrinth Drip Tape

Blue Track Drip Tape

2. Types of Drip Tapes

Inlaid Drip Tape: Pre-manufactured emitters are embedded into the capillary tube during production. Examples include inlaid patch-type drip tape and embedded cylindrical drip pipes.

Labyrinth Thin-Wall Drip Tape: Thin-wall tubes with integrated pressure-reducing flow channels on one side or the middle. Examples include labyrinth drip tape and blue track drip tape.

Features:

Labyrinth Drip Tape:

1. Integrated labyrinth flow channels and drip holes formed via vacuum thermal pressing, ensuring high precision and adhesion.
2. Turbulent multi-outlet design resists clogging.
3. Uniform water distribution (≥85%), with a maximum laying length of 80m.
4. Lightweight and easy to install.

Inlaid Drip Tape:

1. Built-in filter windows for anti-clogging.
2. Turbulent flow design for uniform irrigation.
3. Flexible emitter spacing for broad applicability.
4. Cost-effective.
5. Key Specifications

16	0.18、0.2	0.2、0.3、0.5	2～3	50～100

 

4. Advantages of Drip Irrigation
5. Water, Fertilizer, and Labor Savings:

– Minimizes water leakage and loss through localized irrigation.

– Enables precise fertilizer application, improving nutrient efficiency by over 95%.

– Reduces labor costs via automated control.

2. Temperature and Humidity Control:

– Maintains soil temperature and reduces evaporation.

– Lowers humidity in greenhouses, reducing pest risks.

3. Soil Structure Preservation:

– Gentle water infiltration prevents soil compaction and erosion.

4. Enhanced Yield and Quality:

– Promotes higher yields, earlier harvests, and improved crop quality.

5. Usage Considerations

– Install filters to prevent clogging from impurities.

– Avoid using drip systems for frost irrigation or organic fertilizer application.

– Higher initial investment requires cost-benefit analysis based on crop value.

– Prevent Tape Damage:

– Secure the tape tightly under mulch to avoid gaps.

– Level the soil before installation to eliminate bumps or debris.

– Bury the tape slightly to prevent lens effect from water droplets.

6. Installation Steps
7. Verify equipment specifications and quality.
8. Install water meters, valves, and filters according to design.
9. Connect threaded fittings with sealant tape.
10. Drill holes in the main pipe for bypass connectors.
11. Cut drip tape to length, align with crop rows, and connect to bypasses.
12. Flush the system before sealing ends with plugs.
13. Installation Sequence: Valves → Filters → Main Pipe → Bypasses → Drip Tape → Flushing → Plugs.
