| 摘 要： | 为探究纳米碳增效肥在玉米生产中的肥效效果，以玉米‘九单48’为试验材料，通过田间小区试验研究不同氮素水平下添加纳米碳增效剂对玉米产量以及氮肥利用率的影响。结果表明，添加纳米碳对玉米生育前期影响显著，出苗后41 天相同供氮水平下添加纳米碳与不添加纳米碳处理干物质差异显著，N190+C较N190 显著提高42.4%，N150+C较N150 显著提高39.5%。到玉米生育后期对玉米产量影响不显著，相同供氮水平下添加纳米碳的处理的玉米产量与不添加纳米碳处理差异不显著。同一供氮水平下添加纳米碳处理的肥料利用率和氮素吸收效率比不添加纳米碳的处理高，N150+C、N190 和N190+C处理氮收获指数差异不显著。N150+C处理与N190 处理产量差异不显著，其中N150+C处理在节肥增产方面效果显著。本试验添加纳米碳有利于节约成本、提高氮肥利用效率。因此，在农业生产中，施用化肥并添加适宜浓度的纳米碳有助于节约成本，提高氮肥利用效率。

Effect of Nano-carbon Synergists on Nitrogen Utilization Efficiency and Yield of Maize Under Different Nitrogen Levels |
| |
| Abstract: | This experiment used‘Jiudan 48’corn as the material to find the effect of Nano-carbon synergist on yield and nitrogen utilization efficiency (NUE) of maize under different nitrogen levels, which aimed to explore the effect of Nano-carbon efficiency fertilizers on maize production. The results showed that Nanocarbon affected the corn vegetative stage significantly, 41 days after shooting, the dry weight was significantly different between Nano-carbon treatment and non Nano-carbon treatment under the same nitrogen levels. Under the same nitrogen level, fertilizer and nitrogen utilization efficiency of Nano- carbon treatment was higher than that of non Nano-carbon treatment, differences of nitrogen harvest index of N150 C, N190 and N190 C were not significant. Yield difference between N190 and N150 C was not significant, and N150 C treatment did well in terms of saving fertilizer and increasing production. In this study, adding Nano-carbon was conducive to cost saving and improved NUE. Therefore, in agricultural production, adding appropriate concentration of Nano-carbon to fertilizer can save costs and improve NUE. |
