Does traditional irrigation really not save water?

Traditional irrigation is generally determined by experience, or a fixed irrigation method. For example, if you feel that the ground is short of water, you pull up the water pipe to water the soil. When you feel that the water is almost enough, you will turn off the irrigation equipment. This kind of irrigation is actually unreasonable, and you don't know whether crops really need irrigation, and you are not sure to what extent you can turn off the equipment, which is easy to waste water resources.

The control of intelligent water and fertilizer integrated irrigation system is determined by sensors. Water and fertilizer data in soil can be monitored in real time through soil moisture sensor. When the water content in the soil is lower than the standard value, the system can automatically turn on the irrigation system to irrigate crops. When the water content in the soil reaches the standard value, the system can automatically shut down the irrigation system. By monitoring with real-time data, the irrigation mode is more reasonable, and the irrigation water is saved to the maximum extent on the premise of ensuring soil moisture.

Technical measures to replenish water needed by crops for land. In order to ensure the normal growth of crops and obtain high and stable yield, it is necessary to provide sufficient water for crops. Under natural conditions, it is often because of insufficient precipitation or uneven distribution that the water demand of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the shortage of natural rainfall. Irrigation means watering the land with water. The irrigation principle is to determine the irrigation amount, irrigation times and time according to the water demand characteristics, growth stage, climate and soil conditions of medicinal plants, and to irrigate in a timely, appropriate and reasonable manner. Its types mainly include pre-sowing irrigation, seedling promotion irrigation, growing period irrigation and winter irrigation.
