Coastal land is one of important marginal land types that have been considered as a potential reverse land source to alleviate the shortage of cultivated land. Biochar and pyroligneous acid have attracted much attention because of their good performance in improving the quality of infertile soil. However, the effect of co-application of biochar and pyroligneous acid on peanut production in coastal soil is poorly studied. In this work, a green-house experiment was conducted to compare the effects of individual and combined application of biochar (BC) and pyroligneous acid (PA) on the peanut yield and peanut kernel nutritional quality in a coastal soil, as well as soil properties, and soil microbiome. Compared with the individual application of BC or PA, the co-application of BC and PA dramatically increased peanut pod yield and amino acid contents. The ameliorated soil properties (e.g., water holding capacity) and elevated soil available nutrients (e.g., N, K and P) resulting from the co-application of BC and PA may contribute to the enhanced production of peanuts. High-throughput sequencing showed that both bacterial and fungal communities were altered regardless of individual or co-application, and co-occurrence network of bacterial community was significantly enhanced by the co-application of BC and PA. The abundances of soil beneficial bacteria (e.g. Arthrobacter, Blastococcus and Sphingomonas) and beneficial fungi (Humicola and Chaetomium) were enhanced by the co-application of BC and PA. This study demonstrates that co-application of BC and PA is a potential strategy to reclaim coastal soil for peanut cultivation.

沿海土地是重要的边际土地类型之一，被认为是缓解耕地短缺的潜在反向土地来源。生物炭和焦木酸因其在改善贫瘠土壤质量方面的良好性能而备受关注。然而，生物炭和焦木酸共同施用对沿海土壤花生生产的影响研究很少。在这项工作中，进行了温室试验，比较了生物炭（BC）和焦木酸（PA）单独和联合施用对沿海土壤花生产量和花生仁营养品质以及土壤性质的影响。和土壤微生物组。与单独施用BC或PA相比，BC和PA共同施用显着提高了花生荚产量和氨基酸含量。BC 和 PA 共同施用可改善土壤性质（例如，持水能力）和提高土壤有效养分（例如，N、K 和 P），这可能有助于提高花生的产量。高通量测序表明，无论个体或共同应用，细菌群落和真菌群落都发生了变化，细菌群落的共现网络因BC和PA的共同应用而显着增强。土壤有益细菌的丰度（例如 高通量测序表明，无论个体或共同应用，细菌群落和真菌群落都发生了变化，细菌群落的共现网络因BC和PA的共同应用而显着增强。土壤有益细菌的丰度（例如 高通量测序表明，无论个体或共同应用，细菌群落和真菌群落都发生了变化，细菌群落的共现网络因BC和PA的共同应用而显着增强。土壤有益细菌的丰度（例如BC和PA的共同应用增强了节杆菌属、芽球菌属和鞘氨醇单胞菌属）和有益真菌（腐质霉属和毛壳菌属）。本研究表明，BC 和 PA 的共同应用是回收沿海土壤用于花生种植的潜在策略。
