摘要
总结了国内外对作物氮素吸收利用的评价指标及小麦需氮规律的研究进展,介绍了影响小麦氮素吸收利用的因素,提出了小麦氮素利用率提高的两条途径,即:(1)从小麦基因型入手,挖掘小麦新品种,提高小麦氮素吸收利用的能力;(2)从施氮栽培管理体系入手,改善肥料特性,精准施肥,同时与当地的具体情况结合。最后对提高小麦氮素利用率的研究方向进行了展望。
The evaluation indexes of crop nitrogen uptake and utilization as well as the research progress of wheat nitrogen demand and its factors were summarized in this paper. Afterwards two ways to improve wheat nitrogen utilization efficiency were proposed, i.e.(1) the new wheat varieties were excavated from wheat genotypes to improve the ability of nitrogen uptake and utilization in wheat.(2) startting with the cultivation and management system of nitrogen application, the characteristics of fertilizer should be improved, and the precision fertilization should be combined with the local specific conditions at the same time. Finally, the research direction of improving nitrogen use efficiency of wheat was prospected.
