This weeding tool is designed to make removing weeds with centralized, non-distributed root systems easy. The tip is designed for easy insertion into even fairly compact soil conditions that are difficult for many other tools of a similar nature. The unique features of this tool versus other tools of a similar nature is the tip length may be changed in a manner that no other tool of a similar nature has, to optimize the tool for the weeding conditions, and the tip itself can be changed out for other tip designs, even for non-weeding purposes, such as a shovel or a pick.

An autonomous garden weeding robot includes a chassis, a motorized cutting subsystem, and a drive subsystem for maneuvering the chassis. A weed sensor subsystem is located on the chassis at a first elevation from the ground and a crop/obstacle sensor subsystem is located on the chassis at a second, higher elevation from the ground. The drive subsystem is controlled to maneuver the chassis about a garden. Upon detection of a weed, the motorized cutting subsystem is energized to cut the weed. The motorized cutting subsystem is de-energized after the chassis has moved a predetermined distance and/or after a predetermined period of time. Upon detection of a crop or obstacle, the drive subsystem is controlled to maneuver the chassis away from the obstacle.

A weeding device provides a solution to the problem of removing dandelions and other weeds from a lawn or other area. The core components of the invention are a shaft and handle arranged so that a user can remove weeds while standing, a cutting head and motor configured to cut weeds, and an herbicide injector configured to inject an herbicide into the weed. Generally speaking, the components are configured as follows: the handle is at one end of the shaft and the motor, cutting head, and herbicide injector are at a second end of the shaft. The cutting head is configured to rotate around the herbicide injector to cut portions of the weed while herbicide is injected into the weed by the herbicide injector.

An apparatus for controlling plants in a crop stand with a) at least one liquid reservoir for receiving liquid, b) at least one first liquid line system connected to the at least one liquid reservoir and provided with at least one controllable outlet opening controllable, c) a recognition device for recognizing plants and communicating the position data of the plants to the control device, d) a control device for controlling the at least one valve of the liquid line system,

wherein the recognition device distinguishes plants in the crop stand between wanted plants and unwanted plants, and the control device opens the valves of the at least one first line system so as to exclusively spray the unwanted plants in the crop stand with liquid, i.e., omit the wanted plants. Unwanted plants are damaged or killed by the action of the kinetic and/or thermal energy of the liquid.

Some crops, such as soybeans, grow close to the ground, having a low canopy relative to that of weeds growing interspersed in the crop. A farm implement removes weed growth above the crop canopy. The implement has a chassis with at least three wheels connected to the chassis, a cutting mechanism, mounted at a front end of the chassis, a means for collecting weed growth cut by the cutting mechanism, mounted on the chassis, means for generating and selectively applying rotational torque to at least one of the at least three wheels and means for a user to guide the chassis down the rows in which the crop is grown.

A treatment method for a river system in a reservoir area, comprising: S1. determining whether a time from a current date to the rainy season is less than a preset duration; S2. moving a pressure sensor upward; S3. determining whether the pressure data meets corresponding conditions; S4. determining whether a duration of the pressure data is less than the preset duration; S5. determining whether an interval between the current time and the time for collecting pressure/nitrogen and phosphorus is greater than a preset number of days; S6. acquiring an image information of a river bottom, and sending it to neural network model for identification to obtain a depth of a sludge; S7. determining whether the depth of a sludge has reached a dredging depth, if so, starting a sludge pump to clean up; S8. collecting nitrogen and phosphorus concentration, and removing nitrogen and phosphorus when the concentration exceeds a standard.
