To improve phosphorus (P) uptake efficiency and high yield of rapeseed (Brassica napus) on 2 soil types (yellow-brown earth and acid purplish sandy soil) with low soil P availability, P fertilizer application scheme were studied based on characteristics of soil, fertilizer and rapeseed varieties. Cultivars Zhongshuang 11 (ZS11) and Shengguang 168 (SG168) were investigated on effects of single superphosphate (SSP), diammonium phosphate (DAP), ammonium polyphosphate (APP) and calcium-magnesium phosphate (CMP) on seedling growth, yield, yield-related traits, P uptake and physiological P use efficiency by pot experiments. Results showed that application of P fertilizer significantly promoted plant growth, increased the number of primary branches and siliques per plant, and finally increased seed yield as compared with control of without P. The plant growth of both cultivars on acid purplish sandy soil were significantly better than those on yellow-brown earth in the control. Under the same fertilizer treatment, plant growth of both cultivars on yellow-brown earth were better than those on acid purplish sandy soil, and seed yield of SG168 was significantly higher than that of ZS11 on yellow-brown earth. The seed yield of both cultivars grown on yellow-brown earth treated with DAP and grown on acid purplish sandy soil treated with CMP were the highest among all the treatments with the same soil. In addition, P uptake efficiency of SG168 was higher than that of ZS11 treated with the same fertilizer in the same soil. DAP and DAP or SSP were recommended to apply to cultivar ZS11 and cultivar SG168 grown on yellow-brown earth, respectively. CMP was recommended to apply to both cultivars on acid purplish sandy soil.
