虽然不使用化学品控制土壤传播的植物病原真菌变得越来越困难，但对农业中大量使用农药的关注正在推动更环保的作物保护管理。在这些方法中，利用堆肥抑制真菌病害可能具有很大的潜力。在这项研究中，采用多学科方法表征了两种农场堆肥的微生物群组成，并评估了它们的抑制和生物刺激素活性。本研究中使用的农场堆肥系统能够产生两种具有拮抗微生物群落特征的堆肥，这些微生物群落能够抑制植物病原体并生物刺激植物生长。我们的研究结果表明，诺心菌属和假单胞菌属可能具有抑制作用，而黄杆菌属和链霉菌属似乎可能参与植物生物刺激。总之，本研究结合了不同的技术来表征堆肥，对微生物群落及其在抑制中的作用进行了独特的概述，有助于揭示其复杂性。
While the control of soil-borne phytopathogenic fungi becomes increasingly difficult without using chemicals, concern over the intensive use of pesticides in agriculture is driving more environmentally sound crop protection managements. Among these approaches, the use of compost to suppress fungal diseases could have great potential. In this study, a multidisciplinary approach has been applied to characterize microbiota composition of two on-farm composts and assess their suppress and biostimulant activities. The on-farm composting system used in this study was able to produce two composts characterized by an antagonistic microbiota community able to suppress plant pathogens and biostimulate plant growth. Our results suggest a potential role for Nocardiopsis and Pseudomonas genera in suppression, while Flavobacterium and Streptomyces genera seem to be potentially involved in plant biostimulation. In conclusion, this study combines different techniques to characterize composts, giving a unique overview on the microbial communities and their role in suppressiveness, helping to unravel their complexity.
