Precise prevention and control method and system for pine wilt disease based on space-time law

Abstract

The invention provides a precise prevention and control method and system for pine wilt disease based on a space-time law. The precise prevention and control method comprises the following steps: 1, analyzing an acquired pine forest image by using a trained deep learning model and a space-time law analysis model; 2, feeding back the original image and the analysis result to a matched database for storage; 3, uploading the value data to a special block chain network established among the forest regions through a block chain technology, and carrying out information sharing; and 4, carrying out precise prevention and control on the pine wilt disease according to the long-term space-time record. By using the deep learning technology, under the assistance of the database technology and with the combination of the pine wilt disease evolution law, the method has the advantage that pine wilt disease prevention and control can be more accurately, intelligently and rapidly carried out.

Description

technical field [0001] The invention relates to a disease prevention and control method in a forest area, in particular to a method and system for precise prevention and control of pine wood nematode disease based on spatio-temporal laws. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] my country's pine forest area covers a large area, and pine wood nematode is a devastating disaster to pine trees. It has been listed as a major alien invasive species. Once infected, it will die quickly and even threaten pine forests. At present, most of the prevention and control measures for pine wood nematode disease in my country are drug control and treatment of diseased and dead tree...

AI Technical Summary

Problems solved by technology

At present, most of the prevention and control measures for pine wood nematode disease in my country are drug control and treatment of diseased and dead trees in the forest. The former needs to spray pesticides on large forest areas, which causes great pollution to the environment while protecting it, while the latter is helpless. Therefore, how to effectively, timely and accurately prevent and control pine wood nematode disease has become an urgent problem to be solved.

[0004] However, the inventors found that although the existing dead tree detection and location method for pine wood nematode disease based on deep learning can quickly, efficiently and accurately detect the diseased pine tree and determine the location of the diseased pine tree in time, it is not Cannot be used for early precise prevention and control

In the prior art, there is no method for early precise prevention and control of pine wood nematode disease
