Abstract

The invention discloses an effective identification method for soybean diseases and insect pests, and solves the problems of hysteresis and inaccuracy in the existing soybean disease and insect pest identification and identification aspects based on field visual observation, laboratory analysis and the like in the prior art. The method comprises the following steps that a database is established by utilizing known soybean plant characteristic spectrums under the influence of different types of soybean diseases and insect pests, and various identification parameters involved in soybean plants are extracted and stored under the influence of each type of disease and insect pests in the database in different growth periods; different identification characteristic parameters are endowed with different weights according to the difference of disease and pest types and the difference of the influence of the disease and pest types on plants, and a discrimination model of the disease and pest types is established according to extraction results of the characteristic parameters; and the discrimination model calculation result of the characteristic parameters of the soybean plant to be identified and the discrimination model calculation result of the plant under each disease and insect pest are compared, calculated and matched, so that the identification and identification of the soybean disease and insect pest type are realized. The method has the advantages of real-time performance and quasi-real-time performance.

Description

technical field

[0001] The invention relates to an effective identification method for soybean diseases and insect pests. Background technique

[0002] Soybean, as the main food crop and economic crop in our country, plays a very important role in national economic production, especially in agricultural production. Soybean pests and diseases are not only my country, but also one of the most important agricultural disasters in the world. Up to now, there have been more than 120 kinds of soybean pests and diseases reported in the world, including fungal diseases, bacterial diseases, viral diseases, insects There are different types of diseases and parasitic plant diseases. Different soybean diseases and insect pests have different methods, types and impacts, but different diseases and insect pests will seriously affect the growth of soybeans, resulting in a significant reduction in soybean production or even extinction. The high level and wide range of pests and diseases have ...
