氮、钾配施对强筋小麦产量和品质的影响及其交互作用的研究

采用盆栽试验方法研究了氮、钾配施对强筋小麦产量和品质的影响.结果表明,氮、钾配施对小麦产量和品质有明显的影响.适宜的氮、钾用量配比可提高小麦的穗数、株高、穗长、穗粒数和千粒重.小麦籽粒产量、蛋白质含量和产量、湿面筋含量及沉降值均表现出随氮、钾用量的增加而增加的趋势.氮、钾对强筋小麦产量和品质的提高有着明显的正交互作用.

Effects of grain yield and quality of strong gluten wheat and interaction in combined application of nitrogen and potassium

The pot experiment was adopted to study the effects of combined application of N and K on grain yield and qualities of strong gluten wheat. The results showed that the effects of N and K combined application on grain yield and quality of wheat were obvious. Application of N and K at an appropriate rate and ratio enhanced spike number of wheat, plant height, spike length, grains per spike and 1000-grain weight. The grain yield, protein content and yield, wet gluten content, sedimentation value increased with the increase of N and K application rates. There was significant positive interaction between N and K on grain yield and qualities of strong gluten wheat.
