A mobile irrigation alignment system comprising a base mounted on a first span, a linkage system, and a control box. The linkage system includes a driven arm, drive arm, and control arm. The driven arm is pivotably connected to the base about a vertical axis. The drive arm is pivotably connected to the driven arm about a horizontal axis and includes a distal end configured to rest on an adjacent span. The control arm is linked to the driven arm. The control box determines lateral alignment between the spans based on the control arm as governed by the drive arm and driven arm. The drive arm is configured to retain an upright orientation relative to the driven arm regardless of torsional rotation between the spans so that the position of the control arm and hence the lateral alignment determination is not affected by the torsional rotation between the spans.

Disclosed is a plant protection and management system for a center pivot and linear irrigation system. In the plant protection and management system, the movable platform is configured to provide at least one of an application unit, a seeding-fertilizer spreader unit or a monitoring unit. The application unit is configured to spray agriculture chemicals or fertilizers on crops. The seeding-fertilizer spreader unit is configured to sow seeds of crops. Further, the monitoring unit is configured to monitor crops and collect status data of the crops or status data of environment. According to different requirements on agricultural production, at least one of the application unit, the sowing unit or the monitoring unit can be selectively arranged on the movable platform so as to meet various requirements on plant protections and managements in the process of agricultural production.

A method for classifying plants for agricultural purposes. The method includes: detecting a field section having plants using an optical detection unit inclined toward the field section to obtain image information having a rear image edge having an image width and a front image edge having a larger image width; classifying the plants in the image information into first and second plant classes using an algorithm to treat the plants of the second plant class with a liquid spray agent, in accordance with the classification. The step of classifying comprises a step of reclassifying, in which classified plants are reclassified from the second plant class to the first plant class using the algorithm if they extend in a rear image section of the image information defined by a defined image separation line from a lateral image edge of the image information maximally up to a defined reclassification boundary line.

A spray boom for spraying a fluid on a target includes a boom frame and a spray section coupled to the boom frame. The spray section includes a spray pipe configured to be fluidly coupled to a fluid source and a nozzle coupled to the spray pipe and configured to be fluidly coupled to the fluid source. An actuator is coupled at one end to the boom frame and at an opposite end to the spray section. The actuator is controllably extending and retracting to move the spray pipe and nozzle between a raised position and a lowered position. A trip assembly is coupled between the boom frame and actuator for biasing the spray section to a biased position in which the actuator and nozzle are substantially perpendicular to the underlying surface.
