Drip irrigation is the use of plastic pipes to send water through orifices or drippers on capillary tubes with a diameter of about 10mm to the roots of crops for local irrigation.
It is the most effective water-saving irrigation method in arid and water-deficient areas, and the water utilization rate can reach 95%. Drip irrigation has higher water-saving and yield-increasing effects than sprinkler irrigation, and can be combined with fertilization to more than double the fertilizer efficiency. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for field crop irrigation in dry and water-deficient places. The disadvantage is that the dripper is easy to scale and block, so the water source should be strictly filtered.
Drip irrigation is an irrigation method in which the water and the water and nutrients required by the crops are dripped into the soil of the root zone of the crops evenly and slowly through the pipe system and the irrigator installed on the capillary according to the water requirements of the crops. Drip irrigation does not damage the soil structure, and the water, fertilizer, gas and heat inside the soil are always kept in a good condition suitable for crop growth, the evaporation loss is small, there is no ground runoff, and there is almost no deep leakage. It is a water-saving irrigation method.
The main feature of drip irrigation is that the amount of water is small, and the flow rate of the irrigator is 2-12 liters per hour. Therefore, the duration of one irrigation is long, and the period of irrigation is short, which can achieve frequent irrigation with small water; the required working pressure is low, and it can be more Accurately controlling the amount of irrigation water can reduce ineffective evaporation between trees and will not cause water waste; drip irrigation can also be managed automatically.
