The rhizosphere microbial communities facilitate nutrient uptake, suppress diseases, and enhance plant tolerance to environmental stress through complex interactions. This study reviews the relationship between rhizosphere microbes and kiwifruit, exploring their potential and challenges in improving kiwifruit health and yield. Additionally, it introduces the application of modern molecular techniques and metagenomics in the study of rhizosphere microorganisms. By deepening the understanding of the mechanisms of rhizosphere microbes, this study aims to provide scientific support for the sustainable cultivation of kiwifruit, proposing recommendations for optimizing farming practices through soil management and beneficial microbe inoculation. Keywords Rhizosphere microbes; Kiwifruit health; Nutrient uptake; Disease suppression; Sustainable agriculture 1 Introduction Kiwifruit, originally native to China and initially introduced as an ornamental plant, has now become a crop of significant international economic importance. Known for its high vitamin C content and nutritional value, kiwifruit is widely consumed and has gained popularity globally (Richardson et al., 2018). With the expansion of cultivation areas, kiwifruit has become a major crop in countries like New Zealand, Italy, and China. The health benefits of kiwifruit, including improvements in digestion, immunity, and metabolism, have further driven its demand (Richardson et al., 2018). The rhizosphere, where plant roots interact with surrounding soil microorganisms, plays a crucial role in plant health and productivity. Microbial interactions within the rhizosphere can significantly influence the growth and health of kiwifruit. Beneficial microbes can enhance nutrient uptake, improve soil structure, and provide protection against diseases. However, pathogenic microbes can cause serious crop losses. For instance, fungal pathogens from the Botryosphaeriaceae family, such as Neofusicoccum actinidiae and Neofusicoccum guttata, have been identified as major causal agents of postharvest rot in kiwifruit, highlighting the need to understand and manage these microbial interactions (Feng et al., 2023). This study aims to comprehensively analyze rhizosphere microbial interactions and their impact on kiwifruit health. Specifically, the study will summarize the beneficial and harmful microbial interactions in the kiwifruit rhizosphere, identify key microbial species and their mechanisms, evaluate the impact of these interactions on kiwifruit growth, yield, and disease resistance, and explore strategies for managing rhizosphere microbial communities to enhance kiwifruit health and productivity. Through this research, we hope to provide theoretical support and practical guidance for promoting sustainable kiwifruit cultivation practices.
