Water application methods of modern irrigation sprinklers

Irrigation is a technical measure to irrigate the land with water to supplement the water needed by crops. Irrigation is to liberate people from agriculture that is completely dependent on rainfall through irrigation sprinklers, to ensure the normal growth of crops, and to obtain high and stable crop yields. Irrigation sprinklers allow people to live on drier land and allow more people to be carried on a unit of land. It can be said that irrigation has created civilization.

In ancient times, irrigation equipment was used to draw water from rivers or underground, and windmills were used to draw water to high places. But once the water enters the land that needs to be irrigated, it still flows freely by gravity, or irrigates along the actually dug border.
In modern irrigation, flood irrigation does not make any furrows in the field, and allows it to flow on the ground during irrigation. Gravity is used to infiltrate the soil. It is a relatively extensive irrigation method. It can be divided into border irrigation according to the different methods of moistening the soil. , Furrow irrigation, flood irrigation and flood irrigation.

Flood irrigation is still an important component. It requires less capital, low technology, and is still the mainstream irrigation sprinkler irrigation method in areas where water prices are cheap and labor is low.

Compared with flood irrigation, spray irrigation with irrigation sprinklers can distribute water droplets more evenly. When there is a risk of frost damage in orchards and vineyards, it can also reduce the risk of frost damage to fruit trees.
Sprinkler irrigation also has disadvantages:
1. Compared with flood irrigation, it requires more initial capital investment and technical guidance.

2. The large area of ​​leaf surface wetting caused by sprinkler irrigation may make plant diseases easier to spread, and may also cause leaf burns.

Compared with flood irrigation, sprinkler irrigation has been much more accurate, and the irrigation method with irrigation sprinklers ensures water saving and average water application.
