纳米增效肥料对冬小麦产量及品质影响的研究

目的]探索纳米增效肥料对冬小麦的应用效果。方法]通过不同地域的田间试验,研究纳米增效肥料对冬小麦产量及品质的影响。结果]施用纳米增效肥料,小麦的增产幅度在12.34%~19.76%。纳米增效肥料使小麦蛋白质含量减少7.52%,脂肪含量增加33%。高量尿素肥料比低量型纳米增效肥料增产2.31%,但低量型纳米增效肥料比高量尿素肥料节省肥料用量为150 kg/hm2,有明显省肥效果;中量型纳米增效肥料为秋季一次性施肥,比高量尿素肥料节省春季两次追肥工序,增产17.0%,还有省工效果。结论]该研究为纳米材料在肥料应用方面的机理研究奠定了基础。

Study on Application of Nanometer Biotechnology on the Yield and Quality of Winter Wheat

Objective] The aim was to explore the application effect of nano-synergism fertilizer on winter wheat.Method] The effect of nano-synergism fertilizer on the yield and quality of winter wheat was studied by the field tests in different areas.Result] After applying nano-synergism fertilizer,the increasing range in wheat yield was 12.34%-19.76%.The protein content of the wheat applied by nano-synergism fertilizer was decreased by 7.52% and the fat content was increased by 33%.The yield of wheat applied by the high amount urea fertilizer was increased by 2.31% than that of wheat applied by the low amount nano-synergism fertilizer,but compared with the wheat applied by high amount urea fertilizer,the saved amount of fertilizer per 667 m2 for the wheat applied by low amount nano-synergism fertilizer was 10 kg,which showed obvious fertilization saving effect.The middle amount nano-synergism fertilizer was the fertilizer with onetime application in autumn and it saved two-time topdressing process in spring than high amount urea fertilizer and was increased by 17.0%,which showed labour saving effect.Conclusion] The research laid the foundation for the study on mechanism of application of nanometer material on fertilizer.
