    Sustainable food security is a major challenge in today's world, particularly in developing countries. Among many factors, environmental stressors, i.e., drought, salinity and heavy metals are major impediments in achieving sustainable food security. This calls for finding environment-friendly and cheap solutions to address these stressors. Plant growth-promoting rhizobacteria (PGPR) have long been established as an environment-friendly means to enhance agricultural productivity in normal and stressed soils and are being applied at field scale. Similarly, pyrolyzing agro-wastes into biochar with the aim to amend soils is being proposed as a cheap additive for enhancement of soil quality and crop productivity. Many pot and some field-scale experiments have confirmed the potential of biochar for sustainable increase in agricultural productivity. Recently, many studies have combined the PGPR and biochar for improving soil quality and agricultural productivity, under normal and stressed conditions, with the assumption that both of these additives complement each other. Most of these studies have reported a significant increase in agricultural productivity in co-applied treatments than sole application of PGPR or biochar. This review presents synthesis of these studies in addition to providing insights into the mechanistic basis of the interaction of the PGPR and biochar. Moreover, this review highlights the future perspectives of the research in order to realize the potential of co-application of the PGPR and biochar at field scale.

    可持续粮食安全是当今世界,特别是发展中国家面临的一项重大挑战。在众多因素中,干旱、盐度和重金属等环境压力因素是实现可持续粮食安全的主要障碍。这就需要找到环保和廉价的解决方案来解决这些压力。植物生长促进根际细菌(PGPR)长期以来一直被认为是一种环保手段,可以提高正常和胁迫土壤中的农业生产力,并正在田间规模应用。同样,有人提议将农业废物热解成生物炭,以改良土壤,作为提高土壤质量和作物生产力的廉价添加剂。许多盆栽和一些田间试验证实了生物炭在可持续提高农业生产力方面的潜力。最近,许多研究将PGPR和生物炭结合起来,在正常和压力条件下改善土壤质量和农业生产力,并假设这两种添加剂相辅相成。这些研究中的大多数报告称,与单独施用PGPR或生物炭相比,联合施用处理的农业生产力显著提高。本文综述了这些研究的综合,并深入探讨了PGPR和生物炭相互作用的机理基础。此外,本文还强调了该研究的未来前景,以实现PGPR和生物炭在现场规模上的共同应用潜力。关键词:生物炭;作物生长;干旱胁迫;PGPR;盐度胁迫;土壤改良剂;土壤质量。©作者2022。
