生物防治是通过一种或多种生物来降低病原接种体数量或减弱病原的致病能力的一种防病途径,它包括运用对病原有害的生物,破坏病原的接种体,减少其侵染来源,利用抗病育种或生物工程手段培育高抗的植物品种,以及用农业栽培措施调节病原生物与其拮抗生物之间的生态关系,使之不利于病原物,有利于拮抗生物,以至于寄主植物,同时本文揭示了土壤中一些潜在的天然生物防治现象,如抑菌土壤,及其利用的可能性。
Biological control is one of the pathways through which one or more organisms reduce the number of pathogen inoculum or reduce the pathogenicity of the pathogen. This includes the use of organisms that are harmful to the pathogen, destroying pathogen inoculum, and reducing the source of infection , The use of disease-resistant breeding or biological engineering means to cultivate highly resistant plant species, and agricultural cultivation measures to regulate the ecological relationship between the pathogenic organisms and their antagonistic organisms, so that it is not conducive to pathogens, is conducive to antagonistic organisms, that host plants, At the same time, this article reveals some potential natural biological control phenomena in soils, such as bacteriostatic soil, and their potential utilization.
