Problems solved by technology

[0002] At present, the domestic and foreign irrigation systems for irrigating potted crops and greenhouses have the following problems: poor adaptability to changes in irrigation water pressure; unsteady flow of irrigation water; poor anti-blocking performance of irrigation systems ; The water-saving efficiency of the irrigation system is low; the operating cost of the irrigation system is high; the irrigation system is easy to fall off after installation, which directly affects the irrigation
[0003] Some special cultivation substrates for cultivated plants have poor wettability to the water source, and the water retention performance is much different from that of the soil. Usually, due to the excessive irrigation intensity of the existing drip arrows, the water source flows out along the irrigation point faster, and the lateral infiltration of the soil is poor.
When the cultivation substrate is not evenly moistened during drip irrigation, the bottom of the planting pot will leak and the irrigation will be partial. This will cause serious uneven irrigation in the planting pot, and a large amount of irrigation water will be lost. Increase the frequency of irrigation
If the number of drop arrows in the ordinary drop arrow group is unreasonable, the construction volume will be large during the installation process, resulting in high irrigation costs
