Abstract

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
