[Objective] We aimed to investigate the effects of phosphate treatment on growth dynamics of wheat in wheat/corn intercropping system in southwest hilly 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 tillers, plant height and yield component of wheat trended to increase with the increase of phosphate fertilization amount and all reached the peak for phosphate fertilization amount of 135 kg/hm2. However, the number of tillers, plant height and yield component of wheat all 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. [ABSTRACT FROM AUTHOR] |
