摘　　要：[Objective] Effects of controlled release N fertilizers on wheat growth and yield were studied to provide reference for the application of controlled release fertilizers on wheat. [Method] A field experiment was conducted to study the effects of different types and levels of controlled release N fertilizers on the growth and yield of wheat. In this experiment, a treatment with the application of common urea and potassium chloride（common fertilizer） was established, and treatments with controlled release N fertilizers A and B with different coating materials were also established. [Result] The results showed that under the condition of the same P and K levels, controlled release N fertilizer A at a proportion of 100%, controlled release N fertilizer A at a proportion of 80% and controlled release N fertilizer B at a proportion of 80% could promote wheat growth, optimize yield components, and increase the amount of dry matter accumulation and grain yield. [Conclusion] One-time application of controlled release N fertilizer could be adopted in wheat production to achieve the purposes of saving fertilizer, saving labor and increasing efficiency.[目的]研究控释氮肥对小麦生长发育及产量的影响,为控释肥在小麦上的推广应用提供依据。[方法]利用小麦大田试验,以优化施肥和仅施磷钾肥为对照,选用2种包膜材料不同的控释氮肥A和B,研究控释肥料类型和施肥量对小麦生长发育及产量的影响。[结果]在磷钾水平相同条件下,等氮量控释氮肥A、减施20%控释氮肥A和控释氮肥B,均能够促进小麦生长发育,优化产量构成因素,增加干物质积累量,提高小麦子粒产量。[结论]在小麦生产上可以一次性施用控释氮肥,实现节肥、省工、增效目标。
