The impacts of chemical fertilizers and pesticides have raised public concerns regarding the sustainability and security of food supplies, prompting the investigation of alternative methods that have combinations of both agricultural and environmental benefits, such as the use of biofertilizers involving microbes. These types of microbial inoculants are living microorganisms that colonize the soil or plant tissues when applied to the soil, seeds, or plant surfaces, facilitating plant nutrient acquisition. They can enhance plant growth by transforming nutrients into a form assimilable by plants and by acting as biological control agents, known as plant growth-promoting bacteria. The potential use of bacteria as biofertilizers in agriculture constitutes an economical and eco-friendly way to reduce the use of chemical fertilizers and pesticides. In this context, nanotechnology has emerged as a new source of quality enrichment for the agricultural sector. The use of nanoparticles can be an effective method to meet the challenges regarding the effectiveness of biofertilizers in natural environments. Given the novel sustainable strategies applied in agricultural systems, this review addresses the effects of nanoparticles on beneficial plant bacteria for promoting plant growth.
化肥和农药的影响引发了公众对粮食供应可持续性和安全性的关注，促使人们研究兼具农业和环境效益的替代方法，例如使用涉及微生物的生物肥料。这类微生物接种剂是活的微生物，施用于土壤、种子或植物表面时会在土壤或植物组织中定殖，促进植物对养分的获取。它们可以通过将养分转化为植物可吸收的形式，并作为生物防治剂（即植物促生细菌）来促进植物生长。细菌在农业中作为生物肥料的潜在用途是一种减少化肥和农药使用的经济且环保的方式。在这种背景下，纳米技术已成为农业领域质量提升的新来源。使用纳米颗粒可能是应对生物肥料在自然环境中有效性挑战的有效方法。鉴于农业系统中应用的新型可持续策略，本综述探讨了纳米颗粒对促进植物生长的有益植物细菌的影响。
