摘要
通过不同施氮量对优质小麦产量和品质的影响及肥效分析结果得出,适宜的施氮量,可促进小麦分蘖和穗部发育,增加单位面积有效穗及穗粒数,最终表现增加产量.籽粒品质分析得出,施氮对提高籽粒蛋白质、湿面筋、面团稳定时间、沉降值的效应均很明显,通过数学模拟的产量目标函数氮肥效应方程,进而得出在焦作地区适宜的氮肥施用量,为13.5～14.5kg/666.7m2.氮肥的农业效率、回收率和生理效率,均随施用量增加而下降.
Our analysis of the nitrogenous fertilizer efficiency and its influence on the yield and quality of high-quality wheat showed that proper amount of nitrogenous fertilizer application increased the yield by improving the rate of wheat tillering and the growth of ears. The analysis of the quality of the grains showed that nitrogenous fertilizer application had an obvious effect on increasing the protein of grains, wet gluten, the paste stabilization time, and the sedimentation coefficient. The optimum amount of pure nitrogenous fertilizer application in the district of Jiao Zuo was reached as 13.5～14.5kg/666.7m^2 by means of mathematical equation ,with the increasing amount of nitrogenous fertilizer application, the agricultural, recovery and physical efficiency of the fertilizer decreased.
