There is provided a seedbed holding unit capable of reliably and firmly holding a seedbed with a simple structure, causing no damage to a plant. A seedbed holding unit 160 that holds a seedbed B used in plant cultivation includes a first holding member 170 and a second holding member 180 that are rotatable relative to each other about a predetermined rotation axis A, the first holding member 170 is provided with a first claw part 173 in a fixed state, the second holding member 180 is provided with a second claw part 183 in a fixed state, and the seedbed B is held between the first claw part 173 and the second claw part 183 by rotating the first holding member 170 and the second holding member 180 relative to each other.

A working vehicle is provided with a cabin which covers a control seat on a travel machine body. The cabin has a cabin frame which constructs a framework. At least one frame member of the cabin frame is formed into a C-shaped cross section. A reinforcing plate extending along a longitudinal direction of the frame member is fixed by welding to an opening portion of the frame member. At least longitudinally intermediate portion of the frame member is formed into a hollow shape.

An autonomous travel system is provided with a location acquisition unit, an inertia measuring device, a travel control unit, an initialization control unit, and a condition setting unit. The location acquisition unit acquires a location of a work vehicle by using a satellite positioning system. The inertia measuring device detects an orientation of the work vehicle. The travel control unit causes the work vehicle to travel autonomously along a preset travel route. The initialization control unit carries out an initialization process for the inertia measuring device by obtaining the orientation of the work vehicle on the basis of a value acquired by the location acquisition unit during initialization travel in which the work vehicle travels straight in a predetermined direction. In the condition setting unit, switching from off to on of a power source of the work vehicle is defined as a first starting condition for the initialization process, and acceptance of an instruction for carrying out the initialization process when the power source of the work vehicle is on is defined as a second starting condition for the initialization process.

A method for the production of biomass including: planting rows of poplar saplings or cuttings of the species Populus nigra or Populus tremula in ridges with a density greater than 40,000 units per hectare; cutting the plantation annually at the ridge level for a period of 15 to 20 years, and obtaining in each annual cut poplar stalks having a length less than 7 meters and a diameter less than 6 centimeters, and cutting the poplar stalks transversely into substantially cylindrical blocks of biomass having an adjustable length and a variable diameter, coinciding with the diameter of the poplar stalks in the cutting areas.

An agricultural machine includes a traveling machine body equipped with a working implement including a plurality of ground working mechanisms to perform ground work, and a controller configured or programmed to acquire work information indicating whether or not the ground work is to be performed in each of a plurality of areas of an agricultural field. The controller is configured or programmed to selectively activate each of the plurality of ground working mechanisms based on the work information when the traveling machine body travels in the agricultural field and when the working implement passes through an area of the plurality of areas.

The present disclosure provides generally for a system and method for planting flora, fauna, and dispersing various organisms through drone delivery. The system may comprise of a drone with seedling box that may hold and drop the pods containing flora or fauna. The seedling box may hold the pods with the flora or fauna in them and at specific intervals drop the pod with the flora or fauna. The seedling box may also hold various organisms or other materials and drop these organisms or materials when directed. A seedling box may comprise loading mechanism and deploying mechanism to facilitate accurate, timely deployment of the pods containing the seedlings. A pod may comprise a weighted tip with hollow cavity for seedling placement and a vertical rod for securing seedling during deployment. Where the system comprises uneven number of seedlings, seedling box may include counterweights to provide stability in configured flight patterns for duration of seedling deployment.
