Abstract: The net separation culture pots were empoyed to plant winter wheat Those pots were put into E8H artificial climate box The pH, Olsen P and inorganic phosphate form in cumulic cinnamon soil under vary temperature conditions were studied The results showed that: (1) the pH of wheat rhizosphere and 0～3 mm soil layer were higher than that of 3～8mm and 8～50mm soil layers; (2) the furthest from the wheat roots, the content of Olsen P was higher and the content of Olsen P was reduce with the temperature ; (3) In more near from the wheat roots, the content of Ca2-P, Al-P, Fe-P and Ca8-P, was lower, and the content of O-P and Ca10-P had no obvious change With growth time prolonged and temperature raised , the content of Ca10-P was inerease, Ca2-P, Al-P,Fe-P and Ca8-P were decrease, and O-P had no obvious change
