    Abstract:

    Pot experiments in a glasshouse and field experiments were conducted to investigate effects of soil moisture con tent and phosphorus(P) supply on total P uptake by rice cult ivated in aerobic soil.Results showed that soil moisture and P ap plication did not affect significantly total P uptake by rice cultivated in aerobic soil in the field experiment.But in the pot experi ments,P application increased significantly P uptake by the rice plants,though the effect of soil moisture was not significant.A big interaction between soil moisture and P application was founded.And,thus,the highest P uptake by the rice plants was found in the treatment with 0.0300 g kg-1 of P application rate and 80% in saturated water content.The biggest difference of total P uptake by the rice plants was observed between the application and no application of P under 80% of soil saturated water content and the difference of P uptake by the rice plants between different P application rates was less.Distribution of the P taken up by the rice plants,was in the following order:grain>shoot>root.The results obtained in this experiment could serve as a theoretic basis for water and P management of rice cultivated in aerobic soil in the hilly areas of Southern China.
