Straw return combined with single-season phosphorus application for rapeseed enhances the annual productivity and phosphorus use efficiency under rapeseed-rice rotation.

Straw return and P application had significant ( P < 0.01) or highly significant ( P < 0.001) effects on the total P (TP) content in each soil layer at each stage, and significant effects on the Olsen-P (OP) content in S1 soil layer ( P < 0.05), however, the OP content in S2 soil layer was only affected by the application of P application ( Figures 6 , 7 ).

For yield components, the number of siliques per plant and number of seeds per silique of rapeseed under each phosphate fertilizer treatment showed a trend of S2 > S1, with that under S2 being 0.29–37.98% and 5.73–22.6% higher than S1, respectively.
