Asparagus decline syndrome (ADS) poses a significant threat to asparagus cultivation worldwide. To address this challenge, a two-year investigation was carried out in Spain to assess the impacts of three soil disinfection strategies on asparagus crops. These included biofumigation with seed pellets, biofumigation using poultry manure pellets, and chemical disinfection with dazomet. In addition to evaluating the potential of these treatments to alleviate ADS, the research also focused on identifying the physiological changes linked to the syndrome by examining indicators of oxidative metabolism, hormonal equilibrium, and phenolic compound profiles. Among the treatments evaluated, biofumigation with pellets enhanced vegetative growth, photosynthetic pigment accumulation, antioxidant capacity, and hormonal homeostasis, with these improvements becoming more pronounced in the second year. This approach appeared to promote a healthier physiological status in asparagus plants, likely through improved soil health and reduced biotic and abiotic stress perception. In contrast, chemical disinfection with dazomet, despite initially stimulating some physiological responses, was associated with elevated oxidative stress. Overall, the findings suggest that organic-based soil treatments, particularly biofumigation, represent a promising strategy to strengthen asparagus vigor and resilience against ADS. Further studies are needed to assess their long-term effects in perennial cultivation systems.
芦笋衰退综合征（ADS）对全球芦笋种植构成了重大威胁。为应对这一挑战，在西班牙开展了一项为期两年的调查，以评估三种土壤消毒策略对芦笋作物的影响。这些策略包括使用种子颗粒进行生物熏蒸、使用家禽粪便颗粒进行生物熏蒸以及使用棉隆进行化学消毒。除了评估这些处理方法缓解ADS的潜力外，该研究还通过检查氧化代谢指标、激素平衡和酚类化合物谱，专注于确定与该综合征相关的生理变化。在所评估的处理方法中，使用颗粒进行生物熏蒸促进了营养生长、光合色素积累、抗氧化能力和激素稳态，这些改善在第二年变得更加明显。这种方法似乎通过改善土壤健康以及减少生物和非生物胁迫感知，促进了芦笋植株更健康的生理状态。相比之下，使用棉隆进行化学消毒尽管最初刺激了一些生理反应，但与氧化应激升高有关。总体而言，研究结果表明，基于有机的土壤处理方法，特别是生物熏蒸，是增强芦笋活力和抵御ADS能力的一种有前景的策略。需要进一步研究来评估它们在多年生种植系统中的长期影响。
