确定促进作物生产的田间管理做法，同时保持土壤健康，对于在不断变化的世界中保持长期粮食生产至关重要。此外，提供实验证据来支持传统农业做法的使用对于确保可持续农业是必要的。在此，我们进行了一项为期12年的长期试验，研究了不同施肥类型（对照、无机肥、有机肥）和种植制度（连作和轮作）组合对作物（烟草）产量和与土壤健康相关的多种土壤属性的影响，包括土传病原体和分解者的比例、土壤微生物多样性、微生物网络稳定性和生物量。营养池和微生物资源限制。我们的长期试验表明，与其他管理组合相比，有机肥与轮作组合使作物产量提高至少40%，改善了土壤养分库（如土壤有机质含量），提高了土壤分解者的相对比例，促进了细菌和真菌网络的稳定性和生物多样性。此外，与其他管理组合相比，这种联合处理缓解了微生物资源的限制，并将潜在真菌植物病原体的丰度降低了至少20%。综上所述，我们提供的实验证据支持有机施肥与轮作管理相结合有助于保持土壤长期健康、作物生产和经济产出。
Identifying field management practices to promote crop production, while conserving soil health is essential to maintain long-term food production in a changing world. Also, providing experimental evidence to support the use of traditional agricultural practices is necessary to secure sustainable agriculture. Here, we conducted a long-term 12-year experiment to investigate the impact of different combinations of fertilization type (control, inorganic fertilizer, organic fertilizer) and cropping regimes (continuous cropping and rotation cropping) on the crop (tobacco) production and multiple soil attributes associated with soil health, including proportions of soilborne pathogens and decomposers, soil microbial diversity, microbial network stability and biomass, nutrient pools and microbial resource limitations. Our long-term experiment supports that the combination of organic fertilizer with rotation cropping increased crop production by at least 40% compared to the other management combinations and improved soil nutrient pools (e.g. the content of soil organic matter), improved the relative proportion of soil decomposers, and promoted bacterial and fungal network stability and biodiversity. Furthermore, this combination treatment relieved microbial resource limitation and reduced the abundance of potential fungal plant pathogens by at least 20% compared to other management combinations. In summary, we provide experimental evidence to support that the combined use of organic fertilization and rotation cropping management can help maintain long-term soil health, crop production, and economic outputs.
