Problems solved by technology

Although there are also a small number of simple man-operated fertilizers, these tree fertilization methods and methods have shortcomings and are not scientific enough.
On the one hand, manual fertilization has a large repetitive workload, low efficiency, relatively high labor intensity, poor working environment, high environmental pollution, and great damage to other surrounding vegetation; The root system of the tree is injured, so the phenomenon of poor growth of the tree is more common

Embodiment Construction

[0027] First of all, according to the diameter of the trunk, establish a correspondence table for the distance between the corresponding fertilization hole and the tree, the number of fertilization holes, the depth of the fertilization hole, and the amount of fertilization per hole. The establishment of this table needs to be summarized based on experience and experimental data. Different tree species in different regions There will be different data, and the data can be corrected. For general fruit trees, the following relationship correspondence table is suitable, see Table 1.

[0028] Table 1:

[0029] Tree diameter D The distance R between the fertilization hole and the tree Number of fertilization holes N The distance R between the fertilization hole and the tree Fertilization hole depth Fertilization amount per hole D<=50mm

[0030] Then measure the trunk diameter to the trees to be fertilized, compare the diameter with the relationship correspon...

Abstract

The invention discloses a tree fertilizer application control method and an automatic control system for an automatic fertilizer applicator. The method comprises the steps of establishing a corresponding relation table among the amount of fertilizer application holes, the distances from the fertilizer application holes to a tree, the drilling depths of the fertilizer application holes and the single-hole fertilizer application amount according to the diameter of a tree trunk; measuring the diameter of the tree trunk by using a visual sensor, comparing the diameter with the corresponding relation table, and selecting corresponding data of the amount of the fertilizer application holes, the distances from the fertilizer application holes to the tree, the drilling depths of the fertilizer application holes and the single-hole fertilizer application amount; and determining accurate drilling positions of a fertilizer application driller by taking the data as the action basis of a cantilever and the fertilizer application driller, and then, drilling for fertilizer application at the periphery of the tree. The automatic fertilizer applicator is provided with a controller, a plurality of sensors and electromagnetic valves, so that the automatic drilling for fertilizer application of the fertilizer applicator becomes possible; in addition, the fertilizer application operation is more scientific, and the main root system is not easily injured.

Description

technical field [0001] The invention relates to the field of garden automation, in particular to a method for controlling fertilization of trees and an automatic control system for fertilizing machines. Background technique: [0002] With the continuous improvement of people's material and cultural living standards, the continuous increase of labor costs and the shortage of young and middle-aged labor, people have a stronger demand for greening and beautifying the environment, improving the working environment and strength, and conducting scientific and efficient operation automation equipment. The current method of tree fertilization in the garden industry is still basically manual. For trees of different diameters and types, how far the fertilization holes should be from the trees, and how to distribute them are all subjective and arbitrary. Though there are also a small amount of simple manual operation fertilizer applicators, there are shortcoming and not scientific en...
