Abstract

The invention relates to the technical field of agricultural intelligent machinery, more specifically, to a variable spray control system based on the leaf area index of the canopy of fruit trees and a variable spray method for the canopy of fruit trees. The system obtains the echo energy, target distance, and sprayer driving speed information in real time from the information acquisition terminal, and after calculation by the central processing unit module, it obtains the canopy leaf area index spray basis value L, and realizes real-time spraying according to the change of L value. Variable spray. The detection system and method have the function of online and real-time detection of the leaf area index of the fruit tree canopy, and can spray drugs on different positions of the fruit tree canopy in a targeted manner, which can better meet the requirements of precise pesticide application in orchards. The system has the advantages of strong adaptability, fast response and high detection accuracy.

Description

technical field [0001] The invention relates to the technical field of agricultural intelligent machinery, more specifically, to a variable spray control system based on the leaf area index of the canopy of fruit trees and a variable spray method for the canopy of fruit trees. Background technique [0002] The control of orchard pests and diseases mainly depends on the spraying of chemical pesticides, but the traditional method of continuous pesticide application will have a large amount of pesticide residues, which does not meet the requirements of environmental protection and sustainable development in today's society. The main problem of orchard spraying at the technical level is that it is difficult to calculate the demand distribution of the target dose online and implement the control of the target variable spraying. In order to solve the above problems and meet the requirements of precise spraying in orchards, it is necessary to study the orchard target feature recogn...
