What are the ways of agricultural irrigation?

At present, there are many irrigation methods in agriculture, such as micro-irrigation, sprinkler irrigation, drip irrigation, and intelligent irrigation system based on Internet of Things technology. Then let's learn more about these four agricultural irrigation methods ~

1, drip irrigation

Drip irrigation is a commonly used irrigation method to irrigate soil with water drops, which can meet the needs of some crops for watering methods. The principle of drip irrigation is to use low-pressure pipeline system to dissolve the water dissolved in fertilizer and slowly drip it into the soil at the root of crops regularly and quickly. The advantage of drip irrigation is that it can save water resources, and its water pipes are buried underground, which can free up the use space of ditches. Dissolving fertilizer in water and watering it with crops can reduce the loss of fertilizer and harden the soil.

Step 2: Sprinkle irrigation

Sprinkler irrigation is different from drip irrigation. Drip irrigation means that water naturally flows into the soil, while sprinkler irrigation means that water is sprayed above the land to be watered by pressure, and then small water droplets are formed, which are scattered vertically downward into the land due to the action of gravity, thus realizing water source irrigation. Sprinkler irrigation needs a pressure water source, a water pipeline and a sprinkler. This irrigation method is very advanced. Moreover, it is complicated to realize and troublesome to maintain, so it has a wide coverage because of its large scope. This irrigation method is only suitable for large lawns, not for water-loving crops.

Step 3: Micro-spray

Micro-spray is a form of fog drop sprinkler irrigation and an improved version of combined sprinkler irrigation. Micro-spray irrigation uses rotary faucet and radial faucet to spray water on the upper and lower floors, which solves the defect that sprinkler irrigation can not spray water on soil and can keep the air and soil environment moist. This irrigation method is common in flower farmers' planting, because it can not only keep the humidity in the greenhouse, but also ensure that there is not too much watering every time.

4. Intelligent irrigation

Intelligent irrigation is actually automatic irrigation, which is based on soil moisture. The equipment monitors the soil moisture information in real time through the soil moisture sensor. When the soil humidity is lower than the standard value, the system will automatically turn on the irrigation equipment to irrigate the farmland, and when the soil humidity reaches the standard value, the system will automatically turn off the irrigation equipment. The whole irrigation process is automatic and does not need manual management. In order to avoid uneven irrigation, intelligent irrigation can realize regional control. By placing soil moisture sensors in multiple areas, soil moisture information in different areas can be obtained and can be controlled independently.
