Abstract: Phosphorus(P) uptake, distribution and migration of a new variety of wheat-Zhengmai 7698 in different fertility plots was studied in long term fertilization station which started in 1990 in fluvo-aquic soil. The results showed that P uptake of Zhengmai 7698 were 43.3 kg?ha-1and 49.4 kg?ha-1 under the medium and high fertility level, respectively. The P amounts needed for the formation of 100 kg grain yield are 0.55 and 0.63 kg．Two P absorption peaks were observed. One was during turning green stage to jointing stage. The other was filling period at which time 52.8% and 49.5% of total P uptake of overground were accumulated. The maximum P absorption intensity was 1.14 and 1.76 kg?ha-1?d-1 at initial filling stage. The maximum P accumulation by leaves, 85% of which transferred to other organs when harvested, appeared in jointing stage. The P accumulation of stems reached the maximum value in heading stage, 74.7% of which transferred to other organs. The P accumulation of grains reached the maximum value (38.3 kg?ha-1) in ripening stage, 94.2% of which transferred from leaves and stems. In mature period, 74.3% of the total P uptake was stored in the grain, and the remaining stored in the stems, leaves and glumes.
