Abstract: Simply inoculating inorganic phosphobacteria on rice straw powder showed low capacity to release P from phosphate rock.However,the capacity increased largely after adding a small amount of glucose to the straw medium at same time.This capacity was also stronly enhanced very much when both cellulose decomposing microorganisms and inorganic phosphobacteria were inoculated together in the medium.Particularly,the water extractable P in the sand medium was largely augmented when the inorganic phosphobacteria was inoculated following 4 days incubation with inoculating cellulose decomposing microorganisms.

Key words: photosynthetic model parameter, temperature dependence, optimal temperature, scale, global warming.
