SLIDE GATE TUBING IRRIGATION SYSTEM

Crops that require large amounts of water, generally use conventional furrow irrigation or flood irrigation. However, because the irrigation water flows directly on the field, the water is continuously absorbed by the soil, resulting in uneven absorption of water at the flow beginning and the end. The area at the flow beginning may have too much water, but at the end may not have enough water. Another disadvantage of conventional furrow irrigation and flood irrigation is the longer irrigation time required. These shortcomings are particularly evident in large areas. To solve these shortcomings, Slide Gate Tubing Irrigation is a good solution.

Slide Gate Tubing Irrigation system is a simple and convenient method to solve the shortcomings of conventional furrow irrigation and flood irrigation. There are only 3 compositions in this system: a thin flat tubing, a slide gate set with a Dia. 2 1/2” hole and a sliding sheet for setting on the tubing, a hole puncher to punch holes on the tubing and set the slide gates in the same time. It can be used for sugarcane, rice, cotton, corn and other crops especially for crops which need large water.

The method is to lay suitable thickness flexible tubing on the field, connect to a pump with large water flow. When water is poured into the tubing till it is about 80%~90% full, put the Slid Gate Hole Puncher into the central hole of Slid Gate Set, and use the Hole Puncher to punch the hole in the tubing. Then continue to push Hole Puncher deepen inside, until the barb section of Slid Gate Set is sent in fixed position. The leading part of the barb section has an annular enlarged barb structure. That can fix Slid Gate Set on the tubing. When the Hole Puncher is withdrawn, the water in the tubing comes out from the central hole in the Slid Gate Set. The tubing is important. It must thin for punched by puncher but still durable enough for water deliver.

In the same way assemble the Slid Gate Sets at the appropriate positions along the tubing continually. At last there are many outlets along the tubing for watering. The slid gates on the Slid Gate Set can adjust the flow rate of water or shut off. This will water in precise way, increase the uniformity of irrigation, save water 30-50% and reduce the irrigation time.

In the irrigation process we must deal with air pockets in the tubing for air pockets can significantly restrict water flow in all tubing sizes.

To remove air pockets, punch a small round hole in the top of the tubing using a wire flag, small nail, or a pen/pencil. NEVER USE A KNIFE – the hole will enlarge and rupture the tubing!
