1 Water must be filtered, commonly used 100 mesh nylon mesh or stainless steel mesh; or 120 mesh laminated, mesh filter. This is the key to the normal operation of the drip irrigation system. The filter should be cleaned regularly; the end of the drip irrigation tube should be opened and flushed regularly, usually once a month. 2 Before fertilizing, according to the conditions of the planting crops, design the fertilization plan and prepare the fertilizer. Each irrigated area prepares fertilizer for each application according to the fertilization plan. 3 Before fertilizing, first open the switch of the area to be fertilized for drip irrigation. The fertilizer is then dissolved in the fertilizer tank and fertilization is started after 20 minutes of drip irrigation. The fertilization time in each zone is about 30 to 60 minutes, and the rate of fertilization and fertilization time are adjusted by the switch. 4 After fertilization, the drip irrigation cannot be turned off immediately, and sufficient time for flushing the pipeline should be ensured. This is an important measure to prevent system clogging. The flushing time is related to the size of the irrigated area. Drip irrigation is usually 15 to 30 minutes, and the fertilizer solution in the pipeline is completely discharged. Otherwise, the algae, moss, and microorganisms in the dripper will multiply, blocking the dripper. 5 Select fertilizers with good solubility, such as urea, potassium nitrate, ammonium nitrate, potassium chloride, calcium nitrate, magnesium sulfate and so on. The liquid fertilizer has high nutrient content, good solubility and convenient application, and is the preferred fertilizer for the drip irrigation system. 6 For users who used drip irrigation for the first time, the amount of fertilizer was adjusted on the basis of previous years, and then the fertilizer was dripped using the method of “a few timesâ€. 7 Various organic fertilizers must be clarified and then the clear liquid should be filtered and put into the drip irrigation system. The filtered nylon mesh is usually filtered through 20 mesh and 80 mesh or 100 mesh. 8 Always check the field for leaks, broken pipes, cracked pipes, etc., and maintain the system in time.
