A spray operation method includes obtaining two-dimensional position information of a target area and a three-dimensional model of the target area, and obtaining an operation route according to the two-dimensional position information and the three-dimensional model, where the operation route includes a plurality of waypoints, and at least one of the waypoints is associated with altitude information.

A vegetation partition wire mesh, for use in the vicinity of shores, coasts or roads, includes an outer wire mesh formed by upwardly bending left and right ends of a planar wire mesh, first partition wire meshes formed by upwardly bending front and rear ends of the planar wire mesh, and inner barriers. The first partition wire meshes are fixed inside the outer wire mesh while forming outer walls at front and rear ends thereof. Outer wire mesh nonwoven fabric along the inner surface of the outer wire mesh covers the outer wire mesh. A first partitioning nonwoven fabric along inner surfaces of the upwardly bent portions of the first partition wire meshes covers the upwardly bent portions of the first partition wire meshes. A mixture of soil and seeds is spread at high pressure to fill the inside of the outer wire mesh divided into a plurality of spaces.

An agitator, a planting system including the agitator, and methods of using the agitator to agitate seeds in a hopper, are described. The agitator can be mounted within the hopper of the planting system. The hopper can be transported by an unmanned aerial vehicle to spread the seeds over a geography. The agitator can include one or more arms that oscillate through a sweep angle to move one or more paddles through the seeds. An outlet of the hopper can be within the sweep angle such that the arms and paddles sweep seeds into the outlet as the arms oscillate within the hopper. The sweep angle can vary over time by incrementally increasing the sweep angle during several stages. The varying sweep angle maintains consistent seed mixing and spreading over time. Other embodiments are also described and claimed.

An autonomous vehicle platform and system for selectively performing an in-season management task in an agricultural field while self-navigating between rows of planted crops, the autonomous vehicle platform having a vehicle base with a width so dimensioned as to be insertable through the space between two rows of planted crops, the vehicle base having an in-season task management structure configured to perform various tasks, including selectively applying fertilizer, mapping growth zones and seeding cover crop within an agricultural field.

In one aspect, a row unit for use on an agricultural implement may include a furrow-forming tool coupled to a frame. The furrow-forming tool may be configured to form a furrow in soil present within the field as the row unit is moved across the field. The row unit may also include a first dispensing device configured to dispense a first agricultural product into the furrow. Furthermore, the row unit may include a cultivator coupled to the frame and positioned aft of the furrow-forming tool relative to a direction of travel of the row unit. The cultivator may, in turn, be configured to agitate a lateral swath of the soil. Additionally, the row unit may include a second dispensing device positioned aft of the first dispensing device relative to the direction of travel, with the second dispensing device configured to dispense a second agricultural product into the field.

A spreading control switch structure of a spreader has a spreading tube, a positioning member, a main tube and a switch unit. With the positioning member and the switch unit, the opening and closing state and the spreading amount of the present invention can be adjusted by the circular plate of the valve in the spreading tube. The size of the pipe in the spreading tube is opened to control the blanking amount. On the other hand, the circular plate of the valve can be kept opened in the spreading tube all time without the switching handle being pressed. Therefore, it is easier and less laborious to execute the spreading process.

A planting method of grass-white clover grassland includes the follows steps: (1) plowing and broadcasting Vicia villosa from July to August in a first year, applying a first base fertilizer, harvesting the Vicia villosa from December of the first year to March of a second year; (2) plowing and drilling corn from April to May of the second year, applying a second base fertilizer, weeding in a stage of 5 leaves of the corn, topdressing in a stage of 7-9 true leaves of the corn, and harvesting the corn in September of the second year; (3) plowing and drilling a grass from September to October of the second year, and applying a third base fertilizer; (4) not plowing but broadcasting white clover from May to June of a third year, applying a fourth base fertilizer, completing the planting.

A walk behind broadcast spreader (1) that is propelled by an electric motor (8), rotates a set of powered wheels (7) and an impeller (3). An individual may walk behind the broadcast spreader and simply steer the broadcast spreader as the electric motor propels the broadcast spreader forward.

The present inventors have recognized that a spinner spreader system may be augmented with an air assist system in which an air current is generated to engage particles after they have left the spinner spreader system to thereby enhance the trajectory of the particles. In one aspect, one or more fans with appropriate ductwork may be added below one or more spinning disks to direct jets or curtains of air in the direction of the broadcast pattern of particles leaving the one or more disks. The directed air stream should preferably be faster than the particles leaving the one or more disks, thereby adding additional acceleration to the particles compensating opposing forces.

An agricultural machine for dispensing material to be distributed, which agricultural machine comprises at least one metering element having a metering roller for metering the material to be distributed mounted in a metering housing and is rotatably driven. The metering roller has a plurality of metering wheel segments, each metering wheel segment of the metering roller is assigned a separate drive to drive the metering wheel segments independently of each other to ensure exact metering of the material to be distributed within finely subdivided partial widths of the agricultural machine. The drives of the metering wheel segments of the metering roller are arranged in the interior thereof, for example within a tubular hollow body, on which the metering wheel segments are mounted, such that the drives are ideally accommodated with protection from external influences and in a space-saving manner.
