Technical method of drip fertigation

Drip irrigation is a form of micro-irrigation. It is a drip irrigation method in which water is pressurized, filtered, delivered to the dripper through a low-pressure pipeline, and dripped into the root of the crop. The fertilizer to be applied is dissolved in water. Irrigation is a drip fertigation. Advantages of drip fertigation:


1. Increase the fertilizer interest rate. Conventional fertilization, fertilizer utilization rate is only 30% to 40%, the utilization rate of drip fertilization fertilizer is above, more than one-half more than conventional fertilization.


2. Water saving and uniform irrigation. It is one-half of the water-saving water than the large water temperature, and the uniformity can reach 80% to 90%.


3. Reduce the temperature inside the shed, reduce pests and diseases, inhibit weeds, and improve crop quality.


4. Reduce soil degradation (such as reduced soil pH, secondary salinization of soil) and groundwater pollution.


5. Save labor. Each mu of greenhouse can reduce 10 jobs such as watering, fertilizing and spraying.


6. Increase production and increase income. Generally, the yield can be increased by 15% to 20%.
