摘　　要：烟宏2000是速生丰产的半冬性小麦品种。为了充分发挥烟宏2000的增产潜力,开展了该品种的测土配方施肥试验,研究不同施肥处理条件下的株高、产量及肥料利用率等。结果表明:氮磷钾配方施肥效果最好,在株高、总茎蘖数和千粒重上均显著优于其他处理;无磷区和无钾区表现相当;无氮区表现最差。产量方面,配方施肥区>无磷区>无钾区>无氮区>空白区,3种肥料的增产效果表现为氮肥>钾肥>磷肥。3种肥料的利用率均以配方施肥区最高。在烟宏2000种植过程中,氮肥发挥最大作用,配方施肥是最合理的施肥方法。Yanhong 2000 is a fast growing and high-yielding semi winter wheat variety.In order to fully realize the production potential of Yanhong 2000,this paper studied plant height,yield and fertilizer utilization efficiency under different fertilization conditions by soil testing and formulated fertilization experiments.The results showed that the nitrogen phosphorus potassium formulated fertilization had the best effect(the plant height,total tiller number and 1000-grain weight were significantly better than other treatments);the performance of phosphorus free treatment and potassium free treatment was equivalent;the nitrogen free treatment performed the worst.In terms of yield,the order of each treatment was the formula fertilization treatment>phosphorus free treatment>potassium free treatment>nitrogen free treatment>blank treatment,indicating that the yield increasing effect of the three fertilizers was nitrogen fertilizer>potassium fertilizer>phosphorus fertilizer.The utilization rates of the three fertilizers was highest in the formula fertilization treatment.During the planting process of Yanhong 2000,nitrogen fertilizer played the greatest role,and formulated fertilization was the most reasonable fertilization method.
