Orchard precision fertilization device and orchard precision fertilization method based on machine vision technology

Abstract

The invention relates to an orchard precision fertilization device and an orchard precision fertilization method based on a machine vision technology. The orchard precision fertilization device comprises an image acquisition module, an image processing module, a data analysis module and a fertilization module, wherein the image processing module and the data analysis module are arranged in an industrial control computer; and the fertilization module is composed of an orchard ditching machine, a single chip microcomputer, a stepping motor, a stepping motor driver, a speed measuring circuit, an inverter, a voltage converter, a storage battery and a fertilizer applicator. The fertilization method comprises the following steps: acquiring image information of over-ground parts of fruit trees and processing the acquired image information of the over-ground parts of the fruit trees to obtain various parameters of the over-ground parts of the fruit trees; obtaining a distribution range of absorption roots in fruit tree root systems according to the relation between all the parameters of the over-ground parts of the fruit trees and root system distribution, and the relation between the root system distribution and fertilization; dividing a root system distribution region of the single fruit tree into a plurality of different small regions and determining a needed fertilization amount in each small region; and carrying out precision fertilization on different small regions in the root system distribution region of the single fruit tree.

Description

Technical field [0001] The invention relates to an orchard precise fertilization device and a fertilization method based on machine vision technology, belonging to the technical field of orchard management, and in particular to an orchard precise fertilization that performs precise fertilization within the distribution range of a single fruit tree root system according to the density and density of the root distribution area Fertilization method. Background technique [0002] Fruit trees are one of the important economic crops in our country and have a long history of planting. Fertilization is a key operation link in fruit tree production, and it plays a vital role in fruit quality, yield and growth of fruit trees. The level of mechanization of fertilization for fruit trees in my country is very low, and it is just in its infancy. In some places, fruit trees are fertilized by artificial trenching and spreading. The work is heavy and the efficiency is low. The corrosiveness of c...

AI Technical Summary

Problems solved by technology

The currently used fertilization machinery can only complete mechanical ditching and manual assisted fertilization, and the amount of fertilization cannot be precisely controlled. At the same time, the operating cost is high, the productivity is low, and the labor intensity is high.
