Control method and control system of greenhouse crop diseases and insect pests

Abstract

A method and a system for preventing pests and diseases of greenhouse crops. The method comprises: establishing an alert model for pests and diseases of greenhouse crops; obtaining in real time the type and a current environment parameter of a current crop; matching the type of the current crop against types of crops in the alert model to determine whether the current environment parameter is within an alert threshold range of the types of the crops in the alert model; if it is determined that the current environment parameter is within the alert threshold range, activating an image recognition device to obtain an image of the current crop, and determining, according to the image, whether the current crop is afflicted with a pest or a disease; and initiating, according to a recognition result, a corresponding regulatory mode. Thus, an alert relating to a pest or disease can be performed so as to enable timely preventive measures. Further, by means of image recognition, pest and disease control measures can be timely taken in the event of pest infestation or disease outbreak, diversifying alert methods and increasing the accuracy of prevention of pests and diseases.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preventing and controlling greenhouse crop pests and diseases and a system for preventing and controlling greenhouse crop diseases and insect pests. Background technique [0002] In recent years, with people's large demand for vegetables throughout the year, greenhouse vegetables have flourished. However, on the one hand, the greenhouse environment is closed, and the temperature and humidity are higher than the outside world, which is easy to breed diseases and pests; on the other hand, it is difficult to grow vegetables inside the greenhouse. Pests and diseases are controlled by spraying pesticides in a large area. Once pests and diseases occur, it is difficult to control them.

[0002] In recent years, with people's large demand for vegetables throughout the year, greenhouse vegetables have flourished. However, on the one hand, the greenhouse environment is closed, and the temperature and humidity are higher than the outside world, which is easy to breed diseases and pests; on the other hand, it is difficult to grow vegetables inside the greenhouse. Control pests and diseases through large-scale application of pesticides. Once pests and diseases occur, it is difficult to control

[0003] The occurrence of diseases of greenhouse vegetables is closely related to the environment. The interaction between the adverse environment, pathogens and vegetables is the main cause of the diseases. The expansion of infection and disease. In addition, most of the greenhouses do not strictly implement the planting standards for single-variety planting. Multiple crops are mixed in the greenhouse, which makes the prevention and control of diseases and insect pests more difficult.

The existing early warning methods for pests and diseases are relatively simple and cannot be accurately predicted
