Abstract: A field experiment was conducted to investigate the effects of phosphate fertilizer on LER, the P absorption, phosphate fertilizer absorption efficiency and P intercropping advantage of maize‖faba bean, maize‖soybean, maize‖oil rape intercropping in Quzhou County, Hebei Province. Results showed that, maize‖faba beans LER was 1.24-1.31, maize‖rape LER was 1.20-1.24, and maize‖soybean LER was 1.11-1.15, which were larger than 1, had obvious intercropping advantage. P absorption of different intercropping system were maize‖faba bean > maize‖soybean > maize‖oil rape at three phosphorus levels, were higher than that of monocroped maize by 21.5%-40.2%, 13.3%-22.9%, respectively, and increased with the increasing of P fertilizer except of maize‖oil rape, but the increase rate reduced; P intercropping advantages of three intercropping systems were obvious, and reduced with the increased of P fertilizer except of maize‖soybean. All P fertilizer uptake efficiency of intercropping systems was lower than that of sole cropping maize except of maize‖soybean intercropping with 90 kg/hm². This suggested that, utilizing soil hard dissolved phosphorus could be improved via the activation phosphorus ability of crops intercropped with maize, which was better when maize‖soybean or maize‖faba bean was intercropped, and 90 kg/hm² was suitable P fertilizer application.
