What are the irrigation methods?

1. Drip irrigation: a commonly used irrigation method for watering soil with water drops, which can meet the needs of some crops for irrigation methods.

2. Sprinkling irrigation: Sprinkling irrigation is a mode of pressure spraying, which uses pressure to spray water on the land.

3. Sprinkling irrigation and micro-spraying: water is sprayed into a certain area by using refraction, rotation and radiation micro-nozzles.

4. Micro-spraying: it is a kind of sprinkler irrigation method for fog drops, and is generally used in conjunction with other irrigation technologies.

flood irrigation

Flooding requires digging ditches. Before, it was manpower, then livestock and tractors, and then the most advanced machinery used laser ranging, which depended on economic and geographical conditions, such as the size of the area to be irrigated, the technology available and the labor cost. Plants grow in rows in ditches and ditches or on seedbeds, and water enters farmland along channels and flows in along the edges of ditches or seedbeds.

You can also use hard plastic pipes or aluminum pipes to divert water in the field, open holes in the pipes for irrigation at regular intervals, and connect the channels with siphon pipes. The application of pipeline can control the water flow. Because of the differences in temperature, wind speed, soil and permeability, floods can easily lead to water shortage in some places, and pipelines can be moved, so this uneven phenomenon can be controlled.

Especially if automatic valves are used, the efficiency can be improved. However, soil salinization has been gradually eliminated in developed countries due to the waste of water resources, the need for more labor and the easy rise of groundwater level. But it is still widely used in most developing countries because it only needs a small amount of capital and technology.
