摘要
[目的]优化小麦施肥配方,加快测土配方施肥技术在小麦上的推广应用。[方法]设置不同的配方施肥处理,在小麦上进行氮磷钾肥利用率试验。[结果]小麦氮磷钾肥配合施用,分别比无氮、无磷和无钾区增产1 315.5、573.0、823.5 kg/hm~2,增产率分别为22.6%、8.7%、13.0%。在小麦中高产水平及土壤墒情始终较好的条件下,氮、磷、钾肥的利用率分别为38.91%、32.00%、41.63%。[结论]小麦氮磷钾肥配合施用可显著提高小麦产量。
[Objective] The aim of this study was to optimize the fertilization formula of wheat and accelerate the application of soil testing and formula fertilization technology in wheat. [Method] Different formula fertilization treatments were set and the utilization rate of nitrogen,phosphorus and potassium fertilizer was tested on wheat. [Result] The yield of wheat with combined application of nitrogen,phosphorus and potassium fertilizer was 1 315.5,573.0 and 823.5 kg/hm~2 higher than that with no nitrogen,no phosphorus and no potassium fertilizer treatments respectively,and the increasing rate was 22.6%,8.7% and 13.0% respectively.Under the condition of medium and high yield of wheat and good soil moisture,the utilization rates of nitrogen,phosphorus and potassium fertilizers were 38.91%,32.00% and 41.63%,respectively. [Conclusion] The combined application of nitrogen,phosphorus and potassium could significantly increase wheat yield.
