What Is Underground Irrigation?

The irrigation water is introduced to a certain depth below the field surface, and the soil in the root zone is moistened by the capillary action of the soil for the needs of crop growth. This type of irrigation is also called infiltration irrigation. It is suitable for areas where the upper layer of soil has good capillary properties and the lower layer has poor water permeability.

The underground irrigation system is generally composed of a water conveyance part and a field irrigation part. Water delivery part can be used

1. Does not damage the soil structure, the upper layer can maintain a good aeration state, the three factors of water, heat, and air are coordinated and adjusted automatically, can uniformly transport water and nutrients, provide a stable growth environment for plants, and have a significant increase in yield.

2. The surface water content is low, the evaporation is very little, there is almost no loss of water transportation, and the water utilization rate is high, which is 50% to 70% less than that of sprinkler irrigation.

3. The irrigation water only needs to be transported at low pressure, generally about 0.2 MPa, and the flow rate is small, the head is low, the installed capacity is reduced, and the energy saving effect is good.

4. The 5-10 cm thick soil under the surface is controlled under dry conditions and does not have a warm and humid environment, which can reduce the breeding of pests and diseases, and reduce the cost of pesticides.

There are five main types of underground seepage pipes used in our country: clay-type, plastic-type, tile-type, and rat-type soil holes. This technique is generally applied to crops with flat terrain and deep root systems. | ^[1]
