在大田条件下,研究了添加纳米碳的缓释肥料对超级杂交中稻Y两优1号的产量、氮肥利用率及田面水总氮含量的影响。结果表明,与不添加纳米碳处理相比,添加纳米碳的金正大缓释尿素和添加纳米碳的史丹利缓释复合肥均能促进水稻分蘖的形成,增加孕穗期叶绿素含量,增加干物质累积量、有效穗、每穗实粒数,从而增加稻谷产量,提高氮肥利用率,并能降低田面水中总氮含量,减少氮肥造成的水环境污染。
Under field conditions, the effects of slow release fertilizer with nano-carbon on the yield, nitrogen use efficiency and TN content of super middle-late rice Y Liangyou 1 were studied. The results showed that compared with non-adding carbon nano-carbon, Jinzhongda extended-release urea with nano-carbon added and carbon nano-added Stanley slow-release compound fertilizer all can promote tillering of rice, increase booting chlorophyll content and increase dry matter accumulation , The effective panicle, the number of grains per panicle, so as to increase the yield of rice, increase the utilization rate of nitrogen fertilizer, reduce the total nitrogen content in surface water and reduce the water environment pollution caused by nitrogen fertilizer.
