Many people know a sprinkler - a plastic spinner. They’re sticking her skeleton into the ground, having previously connected the hose, giving pressure, and the long-awaited rain begins in the area of a circle of a certain radius. I also tried to use such a device. There are several modifications on sale, they do not always work steadily. The main inconvenience is that after the end of irrigation of one area, you have to go along moistened soil to rearrange the turntables.
I made a device that eliminates this inconvenience: I made several holes in a plastic bottle with a red-hot needle, attach a flexible hose to the neck of the bottle, give pressure - and watering has begun. To move to the next position, you do not need to trample on the watered soil, just pull the bottle by the hose. If you fix the bottle to a stable platform, for example, to a section of the board, then when moving to the next position, you can not interrupt the water supply by pulling the platform with the fixed bottle by the cord. In addition, with such an irrigation system, an area in the form of a rectangle, rather than a circle, is covered, and when changing the position, there are no dry places, as with circular irrigation. The device is stable.
