Abstract

The invention relates to the technical field of agricultural fertilization, and particularly discloses a corn targeting variable fertilization method, device and application. The device includes: an image acquisition device, a control device and a fertilizer spraying device; wherein, the image acquisition device acquires image information of an area to be fertilized in real time when the fertilization device travels, and the control device respectively controls the fertilizer spraying device according to the image information; the fertilizer spraying device comprises a flat fan-shaped nozzle with a fan-shaped spray shape, and a plane where the fan shape is located is perpendicular to a traveling direction of the fertilization device; the image acquisition device and the fertilizer sprayingdevice are arranged on the same horizontal plane, and a vertical projection of the fan shape on a plane of the area to be fertilized is positioned in middle of a visual field distance of the image acquisition device parallel to the traveling direction; and the image acquisition device and the fertilizer spraying device responsible for fertilizing in the field of view area of the image acquisitiondevice are arranged in a specific manner. The invention also provides a fertilization method and application applying the device. The device applies fertilizer accurately, improves fertilizer utilization rate, and reduces fertilizer pollution.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization, in particular to a method, device and application of corn to target variable fertilization. Background technique [0002] Variable fertilization technology is one of the core contents of precision agriculture. It finely and accurately adjusts the amount of fertilizer applied to crops according to the spatial differences in crop growth environments and the fertilizer requirements of crops, in order to obtain the highest economic benefits and Ecological Benefits. The current variable fertilization technology mainly includes two kinds: the variable fertilization technology based on the prescription map and the online real-time variable fertilization technology based on the sensor. [0003] The variable fertilization based on the prescription map mainly includes the generation of the fertilization prescription map and the variable fertilization operation. Among them, the generati...
