Abstract
|
|
|
|
For 2 years (1993∼1994), study on development of cheap medium far Pleurotus ostreatus revealed that paper sludge contain more CaO and similar T-C, T-N, P₂O_5, MgO but less K₂O than any other medium material in chemical property. Mixed treatment (rice straw+ paper sludge 10, 30, 50%, cotton waste+paper sludge 10, 30, 50%, cotton waste+rice hull 20+paper sludge 10, 30, 50, 70%) is similar or fast a little in mycelial growth and is similar or fast 1∼2 day in period of primordia formation than cotton waste medium, and in the yield to each medium type also increased but excepted in rice hull 20%+paper sludge 70%, especially mixed medium at 7 : 3 ratio of cotton waste and paper sludge is best treatment because it is increased to 21%. In economical analysis, mixed medium at 7 : 3 ratio of cotton waste and paper sludge is increased to 50% compared to cotton waste medium in relative income.
