s2: placing fertilizer in a material storage drawer (221) in advance, pushing the material storage drawer (221) to enable the end of the material storage drawer (221) to be in contact with a limiting box (222), enabling the bottom of a corrugated pipe (223) to extend into the material storage drawer (221), storing water in a water storage tank (211), setting the interval starting time of a PLC (programmable logic controller) (232), and enabling a sealing disc (234) in an initial state to be located at the bottom of a high-pressure tank (235);
s3: after the cylinder (231) is started, the connecting rod (233) drives the sealing disc (234) to move upwards, the sealing disc (234) divides the high-pressure box (235) into an upper part and a lower part, when the sealing disc (234) moves upwards between the bottom surface of the high-pressure box (235) and the bottom edge of the water outlet pipeline (214), the air pressure below the sealing disc (234) is gradually increased, the generated suction force sucks the sealing plate (226) upwards, the sealing plate (226) rotates under the action of the rotating shaft (225), so that the pipe opening of the corrugated pipe (223) is exposed, and the corrugated pipe (223) sucks fertilizer in the material receiving drawer (221) upwards into the high-pressure box (235) along with the continuous upward movement of the sealing disc (234);
s4: when the sealing disc (234) moves upwards between the top edge of the water outlet pipeline (214) and the bottom edge of the discharge sleeve A (236), the generated suction force is reduced, the sealing plate (226) returns to the initial position under the action of gravity, the pipe opening of the corrugated pipe (223) is closed, fertilizer stops entering, the water in the water storage tank (211) is sucked into the high-pressure tank (235) through the water outlet pipeline (214), and the fertilizer is repeatedly stirred in the water through the action of air pressure along with the continuous upward movement of the sealing disc (234);
s5: when the sealing disc (234) moves to the upper part of the bottom edge of the discharge sleeve A (236), the discharge sleeve A (236) is communicated with the outside, and the air pressure in the high-pressure box (235) is higher than the outside air pressure, so that the mixed fertilizer in the high-pressure box (235) flows out along the discharge sleeve A (236), the discharge sleeve B (237) and the discharge sleeve C (238), and plants are irrigated.
6. The method for controlling the differential fertilization rate as claimed in claim 5, wherein a solenoid valve is installed at a communication between the water inlet pipe (212) and the bellows (223).
