集成型化肥增效剂对小麦氮素吸收及产量效应的研究

Effects of integrated fertilizer companion on the N absorption and grain yield of winter wheat

试验研究集成型化肥增效剂 (IFC)对小麦N素吸收及产量的影响结果表明 ,不同生态区不同土壤基施集成型化肥增效剂均有一定增产作用 ,且促进小麦根系生长 ,提高叶片光合功能 ,增强植株吸N能力 ,提高N素吸收效率 ,而N素产量利用效率有所下降。

The study on the effects of Integrated Fertilizer Companion (IFC) on the N absorption and grain yield of wheat shows that applying IFC can increase the root weight, leaf area, chlorophyll content and dry matter amount of wheat. Simultaneously,N absorption and its efficiency are promoted, but N yield utilization efficiency decreases.
