Embodiment Construction

[0035] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 and figure 2 As shown, the present embodiment provides a kind of target variable liquid fertilization device for orchards, including a sensor system, a fertilization mechanism and a controller 2 arranged on the tractor frame; the sensor system is used to detect the three-dimensional data; the fertilization mechanism is used to fertilize the roots of fruit trees; the controller 1 receives the three-dimensional data, performs predictive model calculations on the roots of fruit trees, and then controls the tractor’s walking mechanism and the fertilization mechanism fixed-point quantitatively The fertilizer solution is applied to the roots of the fruit trees in the soil.

[0037] Wherein, the sensing system may adopt an ultrasonic sensor 7 . The ultrasonic sensor 7 collects the time difference between the ...

Abstract

The invention relates to the technical field of agricultural fertilization, and particularly relates to a variable target liquid fertilizer apparatus of an orchard and a fertilizing method. The fertilizer apparatus comprises a sensing system, a fertilizing mechanism and a controller arranged on a tractor frame, wherein the sensing system is used for probing three-dimensional data of positions of branches and leaves of fruit trees, the fertilizing mechanism is used for fertilizing the roots of the fruit trees, and the controller receives the three-dimensional data, calculates a prediction model of the root systems of the fruit trees and then fertilizes fertilizer and water liquor quantitatively at fixed points to the root of the fruit tree in soil by regulating a traveling mechanism and the fertilizing mechanism of a tractor. According to the invention, fruit trees are positioned through the sensing system, the root system distribution is predicted according to growth of branches of the fruit trees, fertilizer and water liquor is fertilized quantitatively at fixed points to the roots of the fruit trees in soil at one time to realize target fertilization and irrigation so as to realize efficient fertilization in orchards and improve the utilization ratio of fertilizers, thereby improving the growth and development, yield and quality of crops of fruit trees. The fertilizer apparatus and the fertilizing method have a good market prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilization, in particular to an orchard target variable liquid fertilization device and a fertilization method. Background technique [0002] The traditional mode of fertilization in orchards is to separate irrigation and fertilization, apply fertilizer in furrows or holes, and use irrigation or natural rainfall to melt the fertilizer and promote fruit tree growth and fruiting. This method has many disadvantages. The root system of the fruit tree is far from being able to absorb the fertilizer, causing too much or insufficient fertilizer in some parts, or it is not absorbed by the root system and is lost to reduce the utilization rate of fertilizer. The growth and development, yield and quality of crops are all affected. [0003] In order to solve the above problems, the present invention makes beneficial improvements. Contents of the invention [0004] (1) Technical problems to be solv...
