[目的]研究不同磷肥处理对西南丘陵区小麦/玉米间套体系中小麦生长动态的影响。[方法]该试验采用田间区组试验，以小麦/玉米间套体系为对象，小麦、玉米分别设置5个供磷水平。[结果]小麦的分蘖数、株高、产量构成随着施磷量的增加均呈增加趋势，在施磷135 kg/hm2处理时达到最大值，随后再继续增施磷肥，无论分蘖数、株高还是产量构成数据均显著降低。[结论]磷肥的施用在一定范围内有助于小麦的生长，超出范围反而会影响最终产量。

We aimed to investigate the effects of phosphate treatment on growth dynamics of wheat in wheat/corn intercropping system in southwest hil y area. [Method] Five phosphate fertilization levels were designed for wheat and corn respectively to investigate the effects of phosphate fertilization level on wheat/corn intercropping system by field block experiment. [Result] The number of til ers, plant height and yield component of wheat trended to increase with the increase of phos-phate fertilization amount and al reached the peak for phosphate fertilization amount of 135 kg/hm2. However, the number of til ers, plant height and yield component of wheat al decreased significantly with the further increase of phosphate fertilization amount. [Conclusion] Phosphate fertilization contributed to the wheat growth in a certain degree. However, excessive phosphate fertilization would affect final yield.
