The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility and improve economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The main basis for fertilization is soil fertility level, crop type, target yield, climate environment and fertilizer characteristics, so as to select appropriate fertilizers, estimate the required amount of fertilizers, and determine the fertilization time and mode.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] During operation, firstly, the external controller and mobile power supply 712 are connected to the micro liquid pump 79 and the driving motor 73. The whole device is divided into two fertilization modes: solid particles and liquid atomization. When solid particles are needed for fertilization, the granular fertilizer is first injected from the feed pipe 216 through the cover plate 215 into the fertilizer barrel 21 for storage. Then the movable operating rod 214 moves in the inner wall of the operating port 213 and drives the control plate 24 to rotate on the bottom wall of the limit ring 23 located at the upper part, so that the control ports 25 of the control plate 24 and the control plate 1 26 gradually overlap, and the solid granular fertilizer falls into the collecting bucket 27 through the control port 25, and then enters the guide bucket 28 through the discharge hopper 28.

How much fertilizer is left in the barrel 21 is convenient for subsequent addition. When fertilization is completed, the cover plate 215 and the feed pipe 216 can be opened by the handle to check the remaining fertilizer in the fertilizer barrel 21. When atomization fertilization is required, the fertilizer and other fertilizer solutions can be injected into the left side of the placement frame 1 through the feed pipe 2 72, and clean water can be injected into the left side of the placement frame 1 through the feed pipe 2 72. The setting of the partition plate 6 can divide the interior of the placement frame 1 into two left and right chambers, the left side is used for granular fertilizer fertilization, and the right side is used for liquid atomization fertilization, and they are separated by the partition plate 6 without interfering with each other. The driving motor 73 is controlled by an external controller to drive the rotating rod 74 to rotate, and the rotating rod 7 When rotating, the mounting base 714, the stirring rod 75 and the stirring blade 76 are driven to rotate, and the fertilizer and the clean water are fully and evenly mixed, and then the liquid fertilizer for fertilization is made. The micro liquid pump 79 is controlled by an external controller to work and the liquid fertilizer is pumped out through the water inlet pipe 711 through the water outlet pipe 710 and the drainage pipe 78, and then the atomized liquid fertilizer is sprayed from the spray head 77 to fertilize the rice in the paddy field. The amount of fertilizer remaining inside can be checked through the transparent observation window 8 on the placement frame 1. When fertilizing, the placement frame 1 and the roller 5 are driven to move in the paddy field by pushing the push handle 3. The two different fertilization methods can meet different fertilization needs and have greater practicality during use.
