What is drip irrigation technology? Generally speaking, what problems will be encountered in irrigating crops?

Drip irrigation is a form of irrigation in which water is dripped into the soil near the root zone of crops through drippers, orifices or drip irrigation belts installed on the capillary. Due to the small amount of drip water, the water drops slowly enter the soil, so under the condition of drip irrigation, the soil moisture in other parts is in an unsaturated state, and the soil moisture mainly diffuses by capillary tension.

Problems encountered in crop irrigation;

1. Traditional irrigation methods: serious waste of water and fertilizer, high cost and poor irrigation effect.

2. Sprinkler irrigation method: The fat part of water is sprayed on the stems and leaves of crops, which can not directly reach the roots, so the water-saving effect is not obvious, the required pressure is high, and the requirements for sprinkler irrigation products are high.

3. Micro-irrigation: it is time-saving and labor-saving, convenient and reliable, and obviously saves water, but the cost is high, and pipes and emitters are easy to block, so it is necessary to install filtering equipment in the head.
