Water-Fertilizer Technology System
Differential pressure fertilizer tank
connected by two thin tubes to the main pipe , and a control valve is set between the two thin tubes to produce a smaller pressure difference so that a portion of the water flows into the fertilizer tank.
venturi fertilizer applicator
When the water flows through a pipe(Venturi throat) which is smaller and thenbigger, the velocity of flow increases and the pressure drops as the water flows throughthe narrow part,resulting in a pressure difference between the front and back,and when there is a smaller inlet in the throat, negative pressure is formed. It can extractthe fertilizer solution from an open-mouth fertilizer tank through a small diameter tube.
gravity self-pressure fertilization method
On the ocasions suitable for gravity drip irmigation or micro-sprinkler imigation,gravity self-pressure fertilization method can be used.
pump-suction fertilizer method
Sketch map of self-pressure fertilizer applicator At this time the use of gravity self-pressure fertilization is very convenient to imigation.
pump-injection fertilizer method
The method of pumping fertilizer is to use a pressure pump to inject fertilizer solution into a pressurized pipe.
