[0046] III. Operating steps for applying pesticides:

[0047] (1)Turn on the power supply, start the controller for self-check, and make the controller enter the working state;

[0048] (2)Start the water source pump. The water source enters from the water source inlet 19, passes through the cylindrical filter screen 18 for filtration, and flows out from the water source outlet 20 into the field irrigation pipeline;

According to the set flow rate, the pesticide solution in the pesticide tank 39 is injected into the cavity behind the mesh of the water source filter through the fertilizer and pesticide filling port 24. Then, the pesticide solution is applied to the farmland along with the water flow.

[0052] IV. Synchronous application of solid fertilizer, liquid fertilizer and pesticide with water:
