| Abstract: | In this paper, the wheat is taken as study object, through monitoring the total phosphorus migration process of plough layer(0~100 cm)in the reproductive period under water and fertilizer coupling, the migration and transformation of total phosphorus in plough layer is analyzed systematically under different amount of irrigation(high 7.6 mm, low 6.1 mm) and fertilizer(high 125 kg/hm 2, low 75 kg/hm 2. |
