Agricultural Drip Irrigation Tape is a thin-walled hose used for agricultural irrigation. It has a small water outlet or labyrinth flow channel inside, which can evenly deliver water droplets to the roots of crops. It has the characteristics of low cost, easy laying, water-saving and high efficiency. It is particularly suitable for the irrigation needs of short-term economic crops such as vegetables, strawberries, watermelons, and cotton. It is a commonly used irrigation tool in modern water-saving agriculture.
Types of agricultural drip irrigation tapes and their performance advantages
Common types of agricultural drip irrigation tapes
1. Labyrinth Drip Irrigation Tape
Features: A labyrinth flow channel is set inside the tape body, and the water flow is controlled by the flow channel structure, and the water output is uniform.
Advantages: Simple structure, low manufacturing cost, suitable for large-scale farmland, commonly used in crops such as cotton, corn, and vegetables.
2. Inline Drip Tape with Flat Emitter
Features: During the production process, the flat dripper is embedded in the inner wall of the tape body, and the drippers are arranged neatly.
Advantages: high water discharge accuracy, strong anti-clogging ability, suitable for crops with high requirements for water uniformity, such as greenhouse vegetables and fruits.
3. Pressure-Compensated Drip Tape
Features: The tape is integrated with a pressure compensation device to ensure stable water flow under different terrains and pressures.
Advantages: Suitable for mountainous or hilly areas with large terrain fluctuations, good drip uniformity, suitable for fruit trees and cash crops.
4. Adjustable Flow Drip Tape
Features: The water outlet can adjust the flow rate according to the water demand of the crop.
Advantages: High flexibility, fine irrigation management, suitable for a variety of crops with different water requirements.
Performance advantages of agricultural drip tape
1. Water-saving and efficient
Directly transport water to the vicinity of the root system, effectively reducing evaporation and leakage losses, and the water saving rate can reach 30% to 50%.
2. Improve yield and quality
Ensure uniform supply of water and fertilizer, promote crop root growth, and improve crop quality and yield.
3. Reduce the occurrence of pests and diseases
Dry the leaf surface, effectively reduce pests and diseases caused by humidity, and reduce the use of pesticides.
4. Convenient construction and low cost
The material is light and easy to lay, suitable for large-scale promotion and use, and has good economic efficiency.
5. Strong adaptability
It can be widely used in various terrains such as flat land, hills, sandy land, etc., with strong adaptability and flexible use.
How to choose drip irrigation tape
1. Adapt according to soil type
1.1. Sandy soil : Large porosity, you need to choose a patch-type drip irrigation tape with a larger dripper flow (≥2.6L/h) or a smaller spacing (20cm) to avoid water infiltration too quickly;
1.2. Clay soil : You need to reduce the dripper flow (≤2.0L/h) and increase the spacing (30cm) to prevent water accumulation from affecting root respiration;
1.3. Loam soil : For general use, choose a patch-type drip irrigation tape with a dripper flow of 1.8-2.6L/h and a spacing of 30cm.
2. Crop demand matching
2.1. Field crops (corn, cotton): labyrinth or high-speed patch drip irrigation tape (wall thickness 0.2-0.3mm) is preferred to reduce costs;
2.2. High value-added crops (fruits, vegetables): Inlaid drip irrigation pipes or patch drip irrigation tapes (wall thickness ≥ 0.3mm) are recommended to ensure uniform water and fertilizer.
| Type | Applicable scenarios | Features | Lifespan |
| 16×0.2×300 | Planting under plastic film, short-cycle crops | Low cost, dripper spacing 30cm | 1-2 years |
| 16×0.3×300 | Field crops (corn, cotton) | Balanced cost performance, medium pressure resistance | 3 years |
| 16×0.4×300 | Long-term planting (orchards, greenhouses) | Made of all raw materials, strong aging resistance | ≥5 years |
Analysis of raw material formula for drip irrigation tape production
Main material formula Conventional formula High-density polyethylene (HDPE): 50 parts, the main brands are 15803, 15813, 10803, etc., with good heat resistance, chemical corrosion resistance and mechanical strength, can ensure the stability and durability of the drip irrigation tape during use.
Linear low-density polyethylene (LLDPE): 30 parts, the main brands are 0209, 0220, 0210, etc., can improve the flexibility and impact resistance of the drip irrigation tape, making it less likely to break during laying and use.
Low-density polyethylene (LDPE): 15 parts, the main grades are 8008, 5410, 6070, 0760, 0754, etc., which helps to improve the processing performance of the drip irrigation tape and make the raw materials easier to plasticize and shape during the extrusion molding process.
Black masterbatch: 3 parts, used to give the drip irrigation tape a black appearance, play a shading role, reduce the degradation of polyethylene materials by ultraviolet rays, and extend the service life of the drip irrigation tape.
Double-proof masterbatch: 2 parts, with anti-aging and anti-ultraviolet functions, further improve the weather resistance of the drip irrigation tape, so that it can better resist the erosion of natural factors in outdoor environments.
