Some microorganisms also have antagonism to pathogenic microorganisms. Most beneficial microorganisms control diseases due to the production of iron carriers, which are molecular complexes synthesized by microorganisms, which can limit the growth of harmful microorganisms.
On the one hand, the application of microbial agents changed the microbial flora in the rhizosphere; on the other hand, the colonization of microorganisms in the crop root surface and rhizosphere occupied the breeding space of pathogenic microorganisms, indirectly reducing or reducing the occurrence of diseases and insect pests.
Some microorganisms, such as AM mycorrhizal hyphae, can not only absorb nutrient elements beneficial to crop growth, but also increase crop water absorption and improve crop drought resistance due to the massive growth of crop roots.
