A structure and method for three-dimensional restoration of slope soil in an abandoned ion-absorbed rare earth mining area, belonging to the field of ecological restoration technologies. The structure for three-dimensional restoration of slope soil in an abandoned ion-absorbed rare earth mining area provided by the present invention includes an ecological water-harvesting pond, ecological intercepting ditches, an improved soil layer laid on the surface of a to-be-restored slope region and a soil restoration ecological network disposed on the improved soil layer. The improved soil layer, the ecological water-harvesting pond and the ecological intercepting ditches are each provided with a combined plant synusia system. The restoration structure provided by the present invention can effectively improve an extremely degraded ecological environment of the abandoned ion-absorbed rare earth mining area caused by tailings waste land and restore the degraded or polluted mining area soil and environment caused by mine destruction during rare earth mining.

An agricultural application machine for the combined application of seed and granulate on an agricultural area includes a separating device a portioning device, and a control device. The separating device has a rotationally drivable separating element for separating seed grains and the portioning device has a rotationally drivable portioning element for producing granulating portions. The control device matches the rotational movements of the separating element and the portioning element to each other to implement a predetermined depositing relationship of the seed grains and the granulating portions on the agricultural area.

A seeding robot includes a power supply, a frame, an opening device for creating a trench, a seed reservoir, and a seed dispensing apparatus configured to deposit seed in the trench from a dispense point. A pair of driven leading wheels are laterally offset to opposite sides of the dispense point. A trailing wheel is positioned behind, and aligned on a longitudinal axis with, the dispense point. The trailing wheel may serve a pressing function behind the seeding operation. Methods of autonomous seeding with such a robot are also disclosed.

A seed conveyor assembly that delivers seed to a planting surface in a controlled manner to maintain seed placement accuracy within a trench. In one embodiment, a seed guide for a seed conveyor assembly includes a relief portion and an introduction portion that includes at least one protrusion. The protrusion is angled from a side of the introduction portion toward the center of the introduction portion. The end of the protrusion is proximate the center of the introduction portion being further from the relief portion.

A sowing heart control apparatus for controlling a sowing heart with a sowing heart monitoring apparatus having an evaluation unit for determining the occupancy of sowing holes of a rotating seed disk with a seed in operation. The evaluation unit delivers an actual value of the occupancy of one or more sowing holes. The sowing heart control apparatus, depending on a deviation of the actual occupancy value from a predetermined setpoint of the occupancy of one or more sowing holes, controlling actuating elements which influence the occupancy. The invention also relates to a sowing heart and a single seed drill.

A delay period timing system for a seeding implement with a feed control. A distribution network conveys products to the furrow openers, and a feeding mechanism controls flow of products into the distribution network. A flow sensor downstream from the feeding mechanism detects when products are flowing at a sensing location, and a timer measures a delay period between the time the feeding mechanism starts or stops flow and when the flow sensor starts or stops detecting flow. The delay period is adjusted to account for the location of the flow sensor. A method of determining the delay period includes determining the length of the distribution network and determining the speed of flow of the products. The system can be used on seeding implement with or without sectional control.
