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

摘要: 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荆均有一定增立作用，且促进小麦根系生长，提高叶片七舍功能，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。

Abstract: 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．Simuhaneously，N absorption and its efficiency are promoted，but N yield utilization efficiency decreases．
