In recent years, non-host plant rotation has become a feasible path to solve the problem of continuous cropping due to its dual functions of eco-friendliness and disease prevention and yield increase. This paper systematically sorted out the types and transmission mechanisms of common soil-borne diseases of solanaceous crops, and focused on analyzing the interference of non-host plants on pathogenic microorganisms through root secretions and microecological reconstruction. Field experiments showed that rotation systems of different years and combinations significantly reduced the frequency of disease occurrence, improved soil enzyme activity and organic matter content, and improved crop health. Combined with typical cases of greenhouses in North China and tropical open fields, this paper explores the regional adaptability and practical effectiveness of rotation systems. Finally, suggestions for promoting appropriate regional combinations and joint biological control strategies are proposed, in order to provide theoretical support and practical reference for building a sustainable disease management system.

However, with the increase in planting years and the development of intensive production, soil diseases are becoming more and more serious. Among them, soil-borne diseases represented by wilt caused by fungi (such as Fusarium oxysporum f.sp. lycopersici) and bacterial wilt caused by bacteria (such as Ralstonia solanacearum) have caused extensive and lasting damage to Solanum oxysporum crops (Ma et al., 2023; Meshram and Adhikari, 2024). These pathogens can survive in the soil for a long time and spread through water flow, agricultural tools or rhizosphere, especially in facility cultivation systems, where they spread rapidly and explosively (Wang et al., 2023). At present, continuous cropping is widely used in China's facility agriculture and open-field cultivation, which aggravates the occurrence of "continuous cropping disorder". Continuous cropping not only leads to the accumulation of pathogens in the soil, but also destroys the balance of the original soil microbial community, inhibits the growth of beneficial bacteria, and significantly reduces the health of the soil ecosystem (Rhouma et al., 2024). Although there are control measures such as grafting, pesticides, and insect nets, there are problems such as high input costs, poor sustainability, and easy resistance in field operations. In the context of the gradual deepening of the concept of green control of plant diseases, non-host plant rotation has received widespread attention as an ecological regulation measure. Non-host plants refer to plant species that do not have the basis for pathogen infection. Their rhizosphere environment has no host induction ability for specific pathogens, and even has an inhibitory effect (De Corato et al., 2020; Zhou et al., 2023). Recent studies have found that planned crop rotation with non-host species such as Gramineae, Leguminosae, and green manure plants can not only interrupt the life cycle of pathogens, but also restore and improve soil microbial diversity and enhance the self-regulation ability of soil ecosystems (Hong et al., 2023).
