Generally, slow-release fertilizers with constant solubility are used.

Precautions for Drip Irrigation Fertilization

1. It is necessary to install a filter. The water source must be filtered, commonly using 100 mesh nylon or stainless steel mesh; Or use 120 mesh laminated or mesh filters. This is the key to the normal operation of drip irrigation systems. The filter should be cleaned regularly; The end of the drip irrigation pipe is regularly opened and flushed, usually once a month.

2. Before fertilizing, turn on the switch in the area to be fertilized for drip irrigation. Then dissolve the fertilizer in the fertilizer pool, drip for 20 minutes, and start fertilizing. The fertilization time for each zone is around 30-60 minutes, and the fertilization speed and time can be adjusted through the switch.

3. After fertilization, drip irrigation cannot be immediately turned off. Sufficient time should be ensured to flush the pipeline, which is an important measure to prevent system blockage. The flushing time is related to the size of the irrigation area. Drip irrigation usually takes 15-30 minutes to completely discharge the fertilizer in the pipeline. Otherwise, a large number of algae, moss, microorganisms, etc. will proliferate at the drip head, blocking the drip head

4. Choose fertilizers with good solubility. High nutrient content, good solubility, and easy application make it the preferred fertilizer for drip irrigation systems.

5. Adjust the amount of fertilizer appropriately. For users who are using drip irrigation for the first time, adjust the fertilizer application amount based on previous years, and then use the "small amount multiple times" method to drip fertilizer.

6. Regularly go to the fields to check for water leakage, pipe blockage, pipe breakage, pipe cracking, and other phenomena, and maintain the system in a timely manner.
