Drip irrigation tapes can be divided into lateral labyrinth drip irrigation tapes and patch drip irrigation tapes. These two categories are not the same in different environments.

drip irrigation belt is the use of plastic pipes (drip irrigation pipe [3]) to send water to the roots of crops through orifices or drippers on capillary tubes with a diameter of about 10 mm for local irrigation. It is a dripper or drip irrigation tape that enters through a very small outlet orifice, and drips water drop by drop evenly and slowly into the soil near the roots of the crop.

It is currently the most effective water-saving irrigation method in arid and water-deficient areas, and its water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has a higher water-saving and yield-increasing effect. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It can be used for irrigation of fruit trees, vegetables, economic crops and greenhouses, and can also be used for irrigation of field crops in drought and water shortage areas. The disadvantage is that the dripper is prone to scaling and clogging, so the water source should be strictly filtered. At present, domestically-made equipment has basically passed the customs, and regions with conditions should actively develop drip irrigation.

Flank labyrinth drip tape (the labyrinth has a crescent shape and a Great Wall shape), patch drip tape, model: ￠16, of which there is another kind of flank labyrinth drip tape that is ￠8, but it is not within the scope of national standards. The thickness is generally 0.16 0.18 0.20 0.22 0.24mm, and the bottom hole spacing is generally 200 and 300mm. The patch type drip tape can be made into any spacing. ￠8 The maze of drip irrigation belts is divided into the Great Wall shape and the chain shape, and the flow is 2.7L of the Great Wall. The chain shape is 3.4L. ￠16 The flow rate is 2.2-2.4L, and the effluent uniformity does not exceed 5%-10%. Application fields: Suitable for irrigation of crops such as sugar cane, cotton, peppers, potatoes, ground nuts, onions, vegetables, bananas, strawberries, flowers and so on. Suitable for surface and underground irrigation.

1. Flank labyrinth drip tape:

Features:

Labyrinth runners and drip holes are integrally formed by vacuum heat pressing, with good adhesion and high manufacturing precision.

Turbulent flow has many water outlets, and it has strong anti-clogging ability.

Labyrinth runner design, uniform water output, up to 85% or more, and laying up to 60m.

Light weight, convenient installation and management, and low manual installation cost.

2. SMD drip irrigation tape features:

Inner flat dripper drip irrigation tape is an integrated drip irrigation tape with a flat dripper inlaid on the inner wall of the pipe belt. It is widely used in greenhouses and field crops for irrigation. The dripper is integrated with the pipe belt, easy to install and use, low cost, low investment, and the distance between drippers is adjustable. The dripper has a self-filtering window, which has good anti-clogging performance. The labyrinth flow channel has a certain pressure compensation effect. Laying on a flat bottom can reach more than 80 meters.
