Abstract
The interaction between different nitrogen and phosphorus fertilizer in calcareous soil was investigated in a pot experiment, planting rape. The results indicated that effects of the interaction between different N and P on growth and nutrition uptake of rape were significant. At the initial stages, all N treatments restrained the growth of rape, especially the NH4Cl treatment, but as time went by, the growth finally was increased significantly, so nutrition uptake was. And the interaction had little influence on soil available phosphorus, while influencing water extractable phosphorus greatly, especially in the early days, and the analysis of correlation sug-gested there was a close relationship between s water extractable phosphorus and dry matter production(r=0.727**). Thus, the effects of different N on growth of rape were closely related with soil P availability. Such results were beneficial for fertilizer rec-ommendation.
