Trickle irrigation

Trickle irrigation

We combine Israel’s trickle irrigation system and specialized irrigation planning and design to provide a reliable and high price-performance ratio solution for all subsurface and surface trickle irrigation needs. The trickle irrigation system is used for various crops in the whole world, which helps to reduce water consumption, improve crop quality and increase yields. The trickle irrigation pipe can be installed on the ground, under the film, and even under the ground. Because of the material strength, design, and quality of the trickle irrigation pipe, the trickle irrigation system can be used for many years.

Composition of trickle (micro) irrigation system

Trickle irrigation pipe
 
LIN-flat inserted emitter trickle irrigation pipe

■　Non-pressure compensated anti-choking thin-wall trickle irrigation pipe makes use of the latest embedded technology of Metzerplas.
■　The inlet filter area is large with the turbulent flow channel, the anti-choking capacity is strong, and the emitter flow is uniform with high working pressure and convenient transportation.
■　The emitter flow rates are 0.8 l/h, 1.2 l/h, 1.6 l/h, 2.0 l/h, and 4.0 l/h.
■　The wall thickness range is from 0.2 mm to 1.2 mm.
■　Optional diameters: 12, 16, 17, 20, and 22 mm.
■　Anti-root taping type can be produced for subsurface irrigation.
■　Chromatic trickle irrigation pipe can be produced for garden irrigation.
 

ADI-cylindrical pressure compensating trickle irrigation pipe

Performance features:
■　Maximum working pressure: 4.3 bar
■　3 types of pipe size are available (16, 18, and 20 mm)
■　4 types of flow rate are available (1.6, 2.2, and 3.5 l/h)

Features and benefits:
■　The wide channel is applicable to the water source with high impurity content.
■　The filter area of channel inlet is large, and the area of the built-in filter screen is 10 times larger than that of similar products.
■　Labyrinth structure and strong eddy can prevent the impurities from blocking the channel.
■　Quickly enter the pressure compensation mode.
■　Emitter flow is stable, can be adapted to complex terrain, pressure variation is large, and the irrigation uniformity is high.
■　The emitter can be washed automatically when starting and ending the irrigation.
■　Anti-root taping type can be produced for subsurface irrigation.
■　Chromatic trickle irrigation pipe can be produced for garden irrigation.

VARDIT- miniature flat pressure compensation emitter trickle irrigation pipe

■　The miniature economical emitter flow is stable, can be adapted to complex terrain, and the pressure variation is large.
■　The channel inlet filter area is large.
■　It is suitable for water source with more impurities.
■　Emitter flow rate: 0.8, 1.2, and 1.6 l/h.
■　Wall thickness: 0.4-1.2 mm.
■　Inner diameter: 16, 17, 20, 22, and 25 mm.
 

ASSIF-miniature flat pressure compensation anti-siphon emitter trickle irrigation pipe

■　The miniature CAS emitter flow is stable and can be adapted to the complex terrain.
■　The anti-siphon structure can avoid blocking the emitter, which is especially suitable for subsurface trickle irrigation.
■　Emitter flow rate: 0.8, 1.2, and 1.6 l/h.
■　Wall thickness: 0.4-1.2 mm.
■　Inner diameter: 16, 17, 20, 22, and 25 mm.
■　Anti-root taping type can be produced for subsurface irrigation.

Fertilizer distributor

1. The fertilizer distributor is a set of high-efficient fertilizer control equipment, which can adjust the EC and PH values of the water by controlling the process of fertilizer addition. The equipment is usually installed on the bypass of head structure as a fill-up system.
2. The fertilizer distributor can obtain 6 channels of fertilizer injection at the same time, and each channel can be operated independently to realize the following functions: EC control, PH control and the function of maintaining the set concentration without PH/EC control.
3. In addition to the above 6 channels of fertilizer injection, the fertilizer distributor can also adjust the main valve and booster, and can read the water meters and fertilizer meters in addition. The control principle of EC and PH is to actually measure the deviation of EC and PH from the set point through continuously changing the predefined concentration of fertilizer. The record shows the final correction factor, which is used as the next fill-up program data so that the system can reach the set point quickly and smoothly.
