摘要： 在南方双季稻地区,以不施肥和相同施氮量不添加纳米碳肥料增效剂的肥料为对照,研究了纳米碳肥料增效剂改良不同肥料对超级杂交晚稻丰源优299产量形成及氮素释放、氮素吸收利用特性的影响。结果表明:三种肥料品种在添加纳米碳肥料增效剂后,均能协调增加穗数、每穗颖花数、结实率以及千粒重而增产。同时增加纳米碳肥料增效剂后能减缓肥料释放速度,减少肥料流失,提高分蘖以后的稻株叶面积指数,提高干物质积累量,增强氮素吸收利用能力。

Abstract: "In the south double season rice area,compared with the none fertilizers application and the same nitrogen application fertilizers not add the nanometer carbon fertilizer sybergist,we took super late rice Feng yuan you 299 as the experiment material,the effect of the nanometer carbon fertilizer synergist on the rice growth,yield formation and characteristics of nitrogen uptake and utilization were studied.under the different nano-meter urea application rate.The result showed that,the nanometer carbon fertilizer synergist can coordinately increase the number of ears,number of the glume flower per ear,the fertility as well as the 1 000-seeds weight and therefore increase the rice yield.Simultaneously the nanometer carbon fertilizer synergist can slow down the fertilizer release rate,reduces the fertilizer outflow,proposes the rice leaf area index,enhances the dry matter accumulation after tillering stage and enhance nitrogen uptake and utilization ability. "

Key words: Nanometer carbon fertilizer sybergist, Late rice, Yield, Nitrogen utilization
