This study introduces M_CNF/biochar, a novel plant growth stimulant comprising bamboo-derived biochar, boron (B), molybdenum (Mo), and copper (Cu)-carbon nanofibers (CNF). The prepared micro-nano formulation is successfully used to deliver the B–Mo–Cu multi micronutrients to Cicer arietinum (chickpea) plant, with the CNFs acting as a translocator for the micronutrients. The synthesized material is thoroughly characterized for its physicochemical properties using various analytical techniques. The results show that a M_CNF/biochar-dose of 1 g kg⁻¹ soil significantly enhances plant growth, as indicated by an increase in the fresh biomass, root and shoot lengths, and protein and chlorophyll contents. Furthermore, the soil's water-holding capacity increases by more than 90% with the mixing of M_CNF/biochar. The results also reveal that the total nitrogen content of the soil amended with M_CNF/biochar increases more than 4 times, post-30 days of plant growth, indicating an improvement in the nitrogen fixation capacity of the rhizosphere. This study has successfully presented the bamboo-derived biochar modified with micronutrients for sustainable agriculture.

一种由多微量营养素和碳纳米纤维改性生物炭组成的微纳米配方，用于促进植物生长


本研究介绍了M_CNF/生物炭，这是一种新型植物生长刺激剂，由竹子衍生的生物炭、硼 （B）、钼 （Mo） 和铜 （Cu）-碳纳米纤维 （CNF） 组成。制备的微纳米制剂成功地用于将 B-Mo-Cu 多种微量营养素输送到 Cicer arietinum（鹰嘴豆）植物，CNF 充当微量营养素的转运剂。使用各种分析技术对合成材料的物理化学性质进行了彻底表征。结果表明，1 g ^kg-1 土壤的 M_CNF/生物炭剂量显着促进了植物生长，新鲜生物量、根和芽长度以及蛋白质和叶绿素含量的增加表明了这一点。此外，M_CNF/生物炭的混合使土壤的持水能力增加了 90% 以上。结果还表明，在植物生长 30 d后，M_CNF/生物炭改良土壤的总氮含量增加了 4 倍以上，表明根际的固氮能力有所提高。本研究成功提出了用微量营养素改性的竹子衍生生物炭用于可持续农业。
