The invention is an apparatus unit that adjusts the dispersion from a compartment to an aqueous solution in response to an independent variable such as an environmental factor, in order to optimize seeding, marking, warning or treatment. The compartment enables any selection of solids, liquids or gasses to be contained and mixed when ready for dispersion. A preferred embodiment is a solar powered pump, self-contained within a buoy over a shallow tidal pool, for the purpose of distributing seeds for marine vegetation under ideal conditions for propagation. The unit provides for sensing and measurement of the environment, then adapting the dispersion for optimum effect.

A method for micro-ridge mixed-sowing cultivation of rice includes: S1: draining away water at the maturity stage of the preceding crop until reaching a state allowing a harvester to operate; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble to form a rhizosphere layer for rice growth; S3: trenching the field to form ecological trenches; S4: flattening the standing stubble and the smashed stalks on the seedbed surface to form an underlying surface, molding seed-fertilizer-soil compounds into a ridge shape and fall the seed-fertilizer-soil compounds on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, and the seed-fertilizer-soil compounds are obtained by thoroughly mixing rice seeds, chemical fertilizers and soil at a mass ratio of 6 to 14:50 to 70:6,000 to 10,000.

The present invention relates to the technical field of hydroponic culture, in particular to an auxiliary root placement device for hydroponic transplanting. The auxiliary root placement device includes an underframe, a repeated horizontal moving mechanism, a jacking mechanism and a vacuum adsorption mechanism, wherein the repeated horizontal moving mechanism is disposed on the underframe, the jacking mechanism is slidingly connected with the underframe, an output end of the repeated horizontal moving mechanism is fixedly connected with the jacking mechanism, an output end of the jacking mechanism is fixedly connected with the vacuum adsorption mechanism. In the present invention, the jacking mechanism is pushed by the repeated horizontal moving mechanism to drive the vacuum adsorption mechanism to move directly below the cultivation hole on the cultivation plate, and then the vacuum adsorption mechanism is driven to rise upwards by the jacking mechanism, so that the output end of the vacuum adsorption mechanism touches the root hairs of the hydroponic plant through the cultivation hole to adsorb the root hairs tightly to the vacuum suction rod, and then retracts through the jacking mechanism, so that the root hairs smoothly pass through the cultivation hole without being stuck on the cultivation plate, resulting in rotting of the root hairs, and thus ensuring the stable growth of the hydroponic plants.

A work vehicle is presented with which it is possible to prevent an operator from being mislead in cases where the positioning status frequently changes. This work vehicle is provided with: a positioning unit that receives a positioning signal from a satellite positioning system, and measures the work vehicle position on the basis of the positioning signal; a control unit that determines the positioning accuracy on the basis of the positioning status of the positioning unit, and permits autonomous travel when the positioning accuracy is at least a prescribed accuracy; and a notification unit that executes, in accordance with a control performed by the control unit, a first notification indicating that the positioning accuracy is a first accuracy that is at least a prescribed accuracy and a second notification indicating that the positioning accuracy is a second accuracy that is at least a prescribed accuracy. If conditions for transitioning the positioning accuracy from the first accuracy to the second accuracy are satisfied within a first prescribed time since execution of the first notification in accordance with transitioning the positioning accuracy to the first accuracy, execution of the first notification is continued until the elapse of a second prescribed time, and after the second prescribed time has elapsed, the first notification is ended and the second notification is executed.

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.

This autonomous traveling system is provided with a path preparation unit, a forward movement control unit, a backward movement control unit, and a turn control unit. The path preparation unit prepares a plurality of straight line paths. The forward movement control unit causes a rice planting machine to execute work and simultaneously causes the rice planting machine to travel along a straight line path by performing at least autonomous steering. After an operator has stopped the rice planting machine traveling toward an edge of a field, the backward movement control unit causes the rice planting machine to travel backward in an autonomous manner or in accordance with operation by the operator, without causing the rice planting machine to execute any work. On conditions that, after the rice planting machine moving backward by the backward movement control unit has stopped in an autonomous manner or in accordance with operation by the operator and an instruction for forward movement has been provided by the operator, the turn control unit causes the rice planting machine to turn toward a predetermined straight line path by performing at least autonomous steering without causing the rice planting machine to execute any work.
