氮磷钾硫对冬小麦产量及加工品质的调节效应

()
摘要:
试验在中国农业科学院作物科学研究所试验基地进行,以强筋小麦品种为试验材料,研究不同氮磷钾硫肥料处理对小麦产量和品质的影响.结果表明,在高产的条件下以120kg/hm2施氮的处理,产量、千粒重和容重最高,过度施氮使产量、千粒重和容重呈逐渐降低的趋势,子粒硬度随施氮量增加而提高.蛋白质含量、湿面筋含量、形成时间和稳定时间均有随施氮量增加而提高的趋势,增加施氮量显著增加了面包体积.蛋白质含量、湿面筋含量和稳定时间有随施钾量增加而提高的趋势.施磷和硫处理对产量和品质的影响不显著.

Effect of Nitrogen Phosphorus Potash and Sulfur on Wheat Yield and Processing Quality
Abstract:
This experiment was carried out in examination base of Institute of Crop Sciences, Chinese Academy of Agricultural Sciences. The effects of different N, P, K, S fertilizers on high gluten wheat yield and quality were researched. The result showed that the grain yield, kilo-kernel weight and liter weight were the highest when N fertilizer treatment was 120kg/hm^2 at the high yield condition. But they had depressed trend when excess N fertilizer applied. The grain rigidity was increased and protein content, wet gluten content, development time and stable time all have increased trend, and bread volume was remarkable increased with the amount of N-fertilizer added. While protein content, wet gluten content and stable time showed increasing trend with the amount of K-fertilizer added. There was no obvious effect of P and S fertilizer treatments on grain yield and quality in the experiment.
Key words:  Fertilization  Winter wheat  Graintreld  Processing quality
