The application of biochar made from crop straw to soil has already become a research hotspot in the field of agriculture at home and abroad, because it can increase crop production capacity with specific environmental benefits. This review summarized the progress of recent research regarding the molecular mechanisms underlying the effects of biochar on crop growth, with particular emphasis on the interactions between crop roots and biochar in soil. The biological effects of the interactions between fertilizer and biochar application and the probable mechanisms underlying the synergistic effect were discussed. The current work proposed the prospects of biochar in agriculture and would promote the relative researches in China. The recent researches indicated that auxin and related signaling molecules play a key role in the growth stimulation in response to biochar application by promoting the expression of genes controlling cell expansion, loosening of the cell wall, and membrane transport for water and nutrients. Biochar and its interaction with plant roots could directly or indirectly influence the physical, chemical and biological properties of soil, which would regulate the function and synergistic effects of biochar coupled with fertilizer.
将农作物秸秆制成生物炭并施用于土壤，已成为国内外农业领域的一个研究热点，因为它能提高作物产量并带来特定的环境效益。本综述总结了近期关于生物炭对作物生长影响的分子机制的研究进展，特别强调了作物根系与土壤中生物炭之间的相互作用。讨论了肥料与生物炭联合施用的生物学效应以及协同效应的可能机制。当前的工作提出了生物炭在农业中的应用前景，并将推动中国的相关研究。近期研究表明，生长素和相关信号分子通过促进控制细胞扩张、细胞壁松弛以及水分和养分膜转运的基因表达，在响应生物炭施用的生长刺激中起关键作用。生物炭及其与植物根系的相互作用可直接或间接影响土壤的物理、化学和生物学性质，这将调节生物炭与肥料耦合的功能及协同效应。
