Risk prediction method and system based on soil pathogenic bacteria, and storable medium

Abstract

The invention relates to the field of soil risk prediction, in particular to a risk prediction method and system based on soil pathogens, and a storable medium, and the method comprises the steps: determining a soil pathogen risk prediction target region; selecting a sampling point in the target area for soil sampling; extracting pathogen types of the soil at the sampling points to obtain pathogen information; judging whether the pathogenic bacteria information is preset pathogenic bacteria information or not; if yes, carrying out risk prediction on the target area; and dividing a target area needing risk prediction into different risk levels, and establishing a corresponding risk prediction period according to the risk levels. When the period prediction value exceeds a certain range, the target area is marked as a high-risk-level area; and the pathogenic bacteria are predicted, and prevention measures can be taken in advance, so that the pathogenic bacteria pollution to crops in the farmland is effectively reduced, and the probability of contact infection between organisms and human beings or animals is indirectly reduced.

Description

technical field [0001] The invention relates to the field of soil risk prediction, in particular to a risk prediction method, system and storage medium based on soil pathogenic bacteria. Background technique [0002] The global animal husbandry industry produces a large amount of feces every year. These wastes contain a large number of enteric pathogens, with the largest number of Escherichia coli, Streptococcus suis and Salmonella. If they are not treated effectively, they will be discharged into the soil or used as organic fertilizers If it enters the farmland, it will seriously pollute the environment, and the pathogenic bacteria in the soil can easily enter the crops, thereby threatening human health. After entering the soil, pathogenic bacteria can be adsorbed on soil particles or migrate with water flow, which profoundly affects their infection activity and diffusion range. Moreover, pathogenic bacteria can maintain life activities by consuming organic matter content ...
