Abstract: In order to research optimal technological conditions of solid-state fermentation to prepare phosphate-solubile biological fertilizer, the leaves residual of Eucommia ulmoides Olive as carrier, Bacillus megaterium as fermented culture and viable count as index were employed by using the orthogonal test. The results showed that optimal technological conditions of phosphate-solubile biological fertilizer prepared by leaves residual of E. unmolds Olive was as follows: ratio of liquor to material was 1:2.5, substrate thickness was 6 cm, the amount of inoculum was 1.5 mL, temperature was 30 ℃, and the mass ratio of leaves residual of E. ulmoides Olive and waste slag of floraphis was 1:0.4. The maximum viable count of B. megaterium could reach 1.64×109 cfu/g at aforesaid experimental condition. In addition, contents of related indices of the phosphate-solubilizing biological fertilizer prepared by optimal technological conditions were all within the range of national standard. As a result, leaves residual of E. ulmoides Olive could be used as carrier to prepare biological fertilizer.
