The inaccurate application period, fertilization amount, and watering amount will inevitably cause environmental and economic losses. However, determining the application period and application amount of water and fertilizer requires considering land conditions, meteorological factors, and the cost involved, and its complexity makes the decision-making process complicated.

[0009] The remote management module is used for users to remotely control through a friendly operation interface provided by the mobile phone or PC terminal to achieve the purpose of remote management of the farm;

[0010] The precise operation module is used to perform precise operations through intelligent agricultural machinery according to the prediction results and farmers' selections; the wheat is managed in blocks and appropriately optimized for different blocks, so that the model is applicable to the vast majority of scenarios. Through model prediction, the block management is realized to improve the stability of wheat production and growth, and the optimal fertilization period and fertilization amount are fed back to the user through the mobile phone or PC side to realize the function of decision-making assistance for the water and fertilizer application period and fertilization amount in the optimal agricultural planting area, so as to help agricultural practitioners apply water and fertilizer, provide visual and quantitative information support for agricultural workers, precisely manage water and fertilizer, precisely control water and fertilizer to maximize resource utilization, and reduce environmental pollution.

[0011] Preferably, the precise operation module includes a fertilization module and a watering module;

[0012] The fertilization module is used to perform fertilization operations on the wheat field;

[0013] The watering module is used to perform watering operations on the wheat field; the staff operates the fertilization module to perform fertilization operations on the wheat field and performs watering operations on the wheat field through the watering module, improving the operation convenience.

[0014] Preferably, the fertilization module includes a drone body, support arms, propellers, a storage tank, support rods, a discharge pipe and a support plate. Multiple groups of support arms are arranged on the drone body, and a group of propellers are respectively installed on each group of support arms. A storage tank is installed on the drone body. Two pairs of support rods are arranged at the bottom end of the drone body, and a group of support plates are respectively arranged at the bottom end of each pair of support rods. The output end of the storage tank is provided with a discharge pipe. It also includes a fertilizer spreading component, a sealing component, a protection component and a locking component. The fertilizer spreading component is installed on the storage tank, the sealing component is arranged at the top end of the storage tank, the protection component is installed below the storage tank, and the locking component is installed on the protection component; when it is necessary to add fertilizer to the storage tank, the drone body lands on the ground, the protection component protects the output end of the fertilizer spreading component, and at the same time the locking component releases the locking of the sealing component, and then the sealing component is opened, so that the staff can inject the fertilizer into the storage tank. After that, the sealing component seals the top end of the storage tank, and multiple groups of propellers rotate quickly to make the drone body take off. The protection component releases the protection of the output end of the fertilizer spreading component, and at the same time the protection component operates the locking component to perform secondary locking on the sealing component, and starts the fertilizer spreading component, so that the fertilizer in the storage tank is used to perform fertilization operations on the corresponding wheat field through the fertilizer spreading component.

[0015] Preferably, the fertilizer spreading assembly includes a support plate, a driving motor, a rotating shaft, a spiral blade, a connecting rod, a circular tube, a hollow turntable and a material spreading pipe. A support plate is installed inside the storage tank. The driving motor is installed on the support plate. The output end of the driving motor is provided with a rotating shaft, and the bottom end of the rotating shaft extends to the inside of the discharge pipe. The spiral blade is installed on the rotating shaft inside the storage tank, and the bottom end of the spiral blade extends to the inside of the discharge pipe. A plurality of groups of connecting rods are arranged at the bottom end of the spiral blade. The bottom end of the connecting rod is connected to the top end of the circular tube, and the outer wall of the circular tube is in contact with the inner side of the discharge pipe. The bottom end of the circular tube communicates with the top end of the hollow turntable. A plurality of groups of material spreading pipes are circumferentially arranged on the outer wall of the hollow turntable. When fertilizing, the UAV body flies to the corresponding wheat field through a plurality of groups of propellers, and the driving motor is started, so that the rotating shaft drives the spiral blade to rotate, so that the fertilizer inside the storage tank enters the inside of the hollow turntable through the circular tube under the guidance of the spiral blade. At the same time, the rotating shaft drives the circular tube and the hollow turntable to rotate rapidly through a plurality of groups of connecting rods, so that the fertilizer inside the hollow turntable is spread through the centrifugal action of the material spreading pipe, so as to perform a uniform and rapid fertilizing operation on the wheat field.

[0016] Preferably, the sealing assembly includes a first shaft pin, a sealing cover, a U-shaped plate, a second shaft pin, a lead screw and a wing nut. The sealing cover is hinged to the top end of the storage tank through the first shaft pin. The U-shaped plate is installed on the sealing cover. The lead screw is hinged to the storage tank through the second shaft pin, and the wing nut is screwed on the lead screw. After the fertilizer is injected into the storage tank, the staff seals the top end of the storage tank with the sealing cover with the cooperation of the first shaft pin, and then makes the lead screw enter the inside of the U-shaped plate with the cooperation of the second shaft pin, and then rotates the wing nut, so that the bottom end of the wing nut presses against the top end of the U-shaped plate to prevent the sealing cover from opening by itself.

[0017] Preferably, the protection component includes a protection frame, a first tension spring, a telescopic rod, a bracket, a fixed pulley, a vertical rod, a lifting plate, a first rope, a second tension spring, and a bottom plate.

A bottom plate is installed at the bottom end of each pair of vertical rods. A first rope is installed at one end of the lifting plate and the protection frame respectively. Each group of first ropes respectively bypass the bottom end of a group of fixed pulleys; when the UAV body lands on the ground, the self-weight of the UAV body causes the two bottom plates to drive the corresponding vertical rods to rise, so that the two lifting plates rise. When the lifting plates rise, the first ropes pull the protection frame downward in cooperation with the corresponding fixed pulleys, so that while the height of the protection frame decreases, the hollow disc and multiple groups of material spreading pipes are inside the protection frame, and the protection frame provides safety protection for the material spreading pipes. After the fertilizer is added to the storage box, the UAV body rises. The second tension spring causes the height of the lifting plate to decrease, and at the same time, multiple groups of first tension springs cooperate with each other to make the protection frame rise, so that the protection frame releases the protection of multiple groups of material spreading pipes, and at the same time, it avoids the interference of the protection frame on the material spreading of the material spreading pipes.

[0018] Preferably, the locking component includes a pull rod, a vertical plate, a baffle, a third shaft pin, a pressing plate, and a second rope.

A pull rod is installed at the top end of each group of lifting plates. The top end of the pull rod passes through the UAV body and extends above the UAV body. A second rope is arranged between the top end of the pull rod and one end of the pressing plate respectively; when the UAV body lands on the ground, the lifting plate rises, so that the protection frame descends. When the lifting plate rises, it drives the pull rod to rise, so that the pull rod releases the pulling of the pressing plate through the second rope. The pressing plate stands upright under the cooperation of the third shaft pin, the torsion spring, and the baffle. After the UAV body takes off, when the lifting plate descends, the pull rod pulls the pressing plate through the second rope, so that the pressing plate is horizontal and presses and locks the top end of the sealing cover, preventing the wing nut from not being locked tightly and the sealing cover from opening by itself.

[0019] Preferably, it further includes an anti-slip pad. An anti-slip pad is installed at the bottom end of each group of support plates; when the UAV body lands on the ground, the anti-slip pad and the support plate cooperate with each other to stably support the UAV body.
