摘要： The present disclosure discloses a method of promoting rice growth using artificial humic acid synthesized by catalysis of nanoscale Ferric oxide, belonging to the field of nanoscale agriculture. The present disclosure discloses a method for synthesizing artificial humic acid from waste biomass with catalysis of transition metal, including the following steps: adding a mixed solution of an alkali, a transition metal catalyst and water into a biomass raw material, and carrying out catalytic reaction at 160-250° C. for 6-48 hours. The artificial humic acid can accelerate germination of rice, effectively promote growth of the rice (the root activity is improved by 166.76% and the net photosynthetic rate is improved by 72.08%), improve the absorption of water and nutrients and the transport of nutrients by rice roots and improve the ability of rice to resist oxidative stress and salt stress.
