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。
In order to explore the effect of nano-carbon synergist fertilizer on maize production, corn ’Jiu Dan 48’ was used as experimental material to study the effect of adding nano-carbon synergist under different nitrogen levels on yield and nitrogen use efficiency influences. The results showed that the addition of nano-carbon had a significant effect on the growth of maize at early growth stage. There was significant difference between the treatments of adding N and N at the same N level for 41 days after emergence. N190 + C increased significantly by 42.4% N150 increased significantly 39.5%. There was no significant effect on the yield of maize at the late growth stage of maize. There was no significant difference between the treatment of maize at the same level of N supply and the treatment without carbon nano-treatment. The fertilizer use efficiency and N uptake efficiency of the treatments with the addition of nano-carbon at the same nitrogen level were higher than those without the addition of nano-carbon. There was no significant difference in nitrogen harvest index between N150 + C, N190 and N190 + C treatments. N150 + C treatment and N190 treatment yield difference was not significant, which N150 + C treatment in fertilizer and yield a significant effect. The experiment to add nano-carbon is conducive to cost savings, improve nitrogen use efficiency. Therefore, in agricultural production, the application of fertilizers and the addition of appropriate concentrations of carbon nano-carbon help to save costs and improve nitrogen use efficiency.
