Puquan is a hi-tech company dedicated to new irrigation systemsdevelopment and marketing. With the idea-'to supply water wheneverplants need' in mind, Puquan started to explore new theory forirrigation in 2004. Inspired by natural capillary force, a newconcept called trace quantity irrigation (TQI) wascoined and later TQI irrigation technology was invented andpatented, which proved to be more efficient, convenient andadaptive than drip irrigation.
