Description

Technical Field

Drip irrigation is a method of using pipes to send water through the holes or drippers on the capillary tubes to the roots of crops for local irrigation. In the prior art, conventional Glechoma longituba drip irrigation devices usually collect rainwater for drip irrigation. The drip irrigation heads are easily blocked due to impurities and dust in the rainwater, and the device cannot discharge water for drip irrigation of Glechoma longituba.
