Crop disease and pest damage early warning information analysis method

Abstract

The invention relates to a crop disease and pest damage early warning information analysis method, and aims to provide a disease and pest damage early warning information analysis method which is accurate in analysis and reliable in information. The method comprises the steps of determining grid positions on the basis of establishing a disease and pest damage type library and a disease and pest damage basic database, and querying basic data of disease and pest damage in the grid positions at current time through the disease and pest damage basic database; and according to the basic data of the disease and pest damage of grids and meteorological data, outputting disease and pest damage occurrence result values, calculating and judging disease and pest damage occurrence levels, performing early warning reminding according to a preset disease and pest damage early warning level value, judging, obtaining and outputting corresponding disease and pest damage control methods according to the output disease and pest damage early warning levels, drawing level rendering graphs of corresponding disease and pest damages according to the disease and pest damage early warning levels, and making corresponding disease and pest damage early warning analysis reports according to the rendering graphs of different disease and pest damages.

Description

technical field [0001] The invention relates to the field of prevention and control of crop diseases and insect pests, in particular to a method for analyzing early warning information of agricultural crop diseases and insect pests. Background technique [0002] In the prevention and control of crop diseases and insect pests, especially in the prevention and control of winter wheat in the Yellow-Huai-Hai Plain, the pest control technology adopted is to feed back and monitor the images of the diseases and insect pests through the disease and insect pest control system when symptoms of a certain area occur. When the occurrence of pests and diseases occurs, early warning information will be given, which will cause a certain lag in information, resulting in a decrease in the yield of plants that have already experienced symptoms, greatly affecting the yield of winter wheat, and causing huge economic losses to farmers. Contents of the invention [0003] The technical problem to...
