为揭示纳米碳对作物生长的促进作用机理，以玉米东农253为试验材料，通过设置不同供氮水平，利用盆栽试验研究纳米碳对玉米氮素吸收及根系活力的影响。结果表明，N1+C（施氮150 mg·kg-1+纳米碳）、N2+C （施氮200 mg·kg-1+纳米碳）和N0+C（不施氮+纳米碳）处理的玉米植株生物量比N1（施氮150 mg·kg-1）、N2（施氮200 mg·kg-1）和N0（不施氮）分别增加4%、12.29%和32.60%；吸氮量比不添加纳米碳分别增加9.09%、8.33%和42.86%。除此之外，纳米碳的添加对玉米根系活力和土壤酶活性有促进作用，其中添加纳米碳处理的玉米根系活力分别增加2.2倍、2.3倍和1.9倍，根际土壤脲酶分别增加7.89%、28.26%和28.57%。由此可见，纳米碳可提高玉米根系活力，促进氮素吸收，从而促进玉米植株生长。

In order to explore the mechanisms of Nano-carbon on crop growth facilitation, a pot experiment with different nitrogen supplied levels were conducted to study the effects of Nano-carbon on nitrogen absorption and root activity of maize. The results showed that maize biomass in N1+C (Nitrogen 150 mg·kg-1+Nano-carbon), N2+C (Nitrogen 200 mg·kg-1+Nano-carbon) and N0+C (no nitrogen+Nano-carbon) treatments increased 4%, 12.29%and 32.60%than N1(Nitrogen 150 mg·kg-1), N2 (Nitrogen 200 mg·kg-1) and handling N0 (no nitrogen)treatments, and N uptake by maize increased 9.09%, 8.33%and 42.86%, respectively. In addition, addition of Nano-carbon affects maize root and soil enzyme activities. The maize root activities were 2.2, 2.3 and 1.9 times than those of without Nano-carbon treatments, respectively. Urease activities increased by 7.89%, 28.26%and 28.57%, respectively. Therefore, Nano-carbon enhanced roots activities of corn, and promoted the absorption of nitrogen, resulting in the growth of maize.
