1. Irrigation: The principle is shallow irrigation and frequent irrigation, that is, the amount of irrigation should be less at once and the number of irrigation times should be more. The irrigation amount per mu should be between 5-30 cubic meters, or half of the conventional irrigation amount. When the water temperature is low, multiple irrigation should be carried out.

2. Fertilization: Dissolve the fertilizer in a container of 10-30 liters, place the suction tube of the fertilizer applicator into the fertilizer solution, connect the water source, and wait for the water to stabilize. Then, open the valve on the suction tube of the fertilizer applicator and gradually close the valve on the main pipe until the fertilizer applicator can suck in the fertilizer solution normally. After fertilization is complete, close the valve on the suction tube of the fertilizer applicator and open the control valve on the main pipe to continue irrigation for about 10 minutes, so as to flush out the residual fertilizer in the pipe.

3. Maintenance: Be careful not to scratch or puncture the drip irrigation equipment during operation, and cut off the damaged pipe. Insert a suitable plastic or rubber pipe into the drip irrigation equipment or main pipe before continuing to use. When there are many impurities in the water source, regularly open the tail of the drip irrigation belt one by one to flush out the impurities inside the pipe.
