摘要: 为了合理、准确地分析北方冬麦区的小麦产量潜力,找到限制因素,探寻相应的调控技术,提高小麦生产力。归纳了本地区模型模拟的冬小麦产量和高产记录,比较分析了模型模拟和高产纪录产量水平的差异,总结了限制小麦产量差缩小的主要原因与可能的调控技术。得出当前模型模拟结果低于高产记录是因为数据采集年份和数据量的影响;产量性能理论是定量化分析产量差异原因的有效方法;指出北方冬麦区限制小麦产量差缩小的主要原因和调控技术。认为小麦产量提升应从产量差确定、产量性能分析、集成技术等3 个方面依次开展。

Abstract: The aims are to analyze wheat yield potential in the northern winter wheat region of China, and to find out the limiting factors and explore the corresponding control techniques for improving wheat productivity. The yield and high yield record of winter wheat simulated by the native-area model was summarized. The differences between model simulation and high yield record were compared and analyzed. This study summarized the main reasons which limited yield gap reducing and the possible control techniques. It was concluded that the simulation results of the current model were lower than that of the high yield records because of the influence of the data collection year and the amount of data. Yield performance theory was an effective method for quantitative analysis of yield-gap causes. It was pointed out that the main reasons limiting yield gap reducing and control techniques in the northern winter wheat region of China. It is suggested that the improvement of wheat yield should be carried out in three aspects: determining yield gap, yield performance analysis and integrated technology.
