The utility model relates to the technical field of fertilizing devices, in particular to an organic vegetable fertilizing device which is large in coverage width, suitable for a pre-planting period, a seedling period and a middle-later period and small in limitation. Comprising a fertilizer box; two fertilizer hoppers, two fertilizer feeding pipes, a double-output-shaft motor, two driving shafts, two spiral blades and a plurality of fertilizer applying holes are further included, the two fertilizer hoppers are installed on the two sides of the bottom of the fertilizer box respectively, the two fertilizer hoppers are both communicated with a fertilizer cavity of the fertilizer box, the input ends of the two fertilizer feeding pipes are communicated with the interiors of the two fertilizer hoppers respectively, and the output ends of the two fertilizer feeding pipes are communicated with the interiors of the two fertilizer hoppers respectively. The fertilizer hopper and the fertilizer conveying pipes form a channel for conveying fertilizer, the two fertilizer conveying pipes horizontally extend towards the two sides of the fertilizer box, the double-output-shaft motor is installed at the bottom of the fertilizer box, two output shafts of the double-output-shaft motor are in transmission connection with the two driving shafts respectively, and spiral blades are installed on the outer walls of the two driving shafts respectively. The two spiral blades are rotationally mounted in the two fertilizer conveying channels respectively, and a plurality of fertilizing holes are formed in the bottom walls of the two fertilizer conveying pipes.

The application discloses a picking device and relates to the technical field of robots. The picking device comprises a driving track, a conveying assembly and a mechanical hand assembly. The driving track is suspended in the air. The conveying assembly is connected to the driving track and can move along the extension direction of the driving track under the driving of the driving track. The mechanical hand assembly comprises a mechanical arm, a clamping jaw and scissors. One end of the mechanical arm is connected to the conveying assembly, and the other end of the mechanical arm is connected to the clamping jaw and the scissors. The clamping jaw is used for wrapping grapes, and the scissors are used for cutting off the corresponding grapevine of the grapes wrapped by the clamping jaw. The clamping jaw of the application can wrap grapes first, and then control the scissors to cut off the grapevine, so that the grapes can be picked. Since the driving track is suspended in the air, the conveying assembly and the mechanical hand assembly are also suspended in the air. In the process of advancing, the conveying assembly and the mechanical hand assembly will not crush the soil and will not cause serious soil compaction to affect the planting and production of grapes.

This invention provides a method for planting multiple crops of fast-growing crops per year with alternating periods of vigorous growth and seedling stage. The method includes soil improvement in the planting area to ensure that the organic matter content in the soil is greater than or equal to a preset value, eliminating the need for tilling for two years; dividing the planting area into a first zone and a second zone, with a wheeled or tracked path between them; inhibiting crop growth in the first or second zone to alternate between vigorous growth and seedling stage crops; and applying fertilizer to the first or second zone, specifically in the following situations: applying fertilizer to the first or second zone after harvest; and / or applying fertilizer to the first or second zone during the seedling stage. This invention achieves alternating periods of vigorous growth and seedling stage crops on the same land by inhibiting crop growth in the first or second zone, thereby improving sunlight utilization. Furthermore, the wheeled or tracked path prevents damage to the root system during the vigorous growth or seedling stage.
