Sequential Cultivation of Agaricus blazei Murrill with Waste from Agaricus bisporus Cultivation

Agaricus Blazei Murrill was cultivated in sequential cultivation with the unfermented waste from Agaricus bisporus cultivation.The results suggested that the method was applicable.The yield of A.Blazei Murrill cultivated on April 15 was 3.41 kgm-2, which increased about 8.20% and 3.31% as compared to those cultivated on March 15 and April 1, respectively.Formulation of the culture medium significantly affected the growth vigor and color of the hypha.The medium consisting of 1.0 kg soybean powder, 0.25 kg yeast powder and 0.2 kg ammonium sulfate resulted in the fastest growing white hypha.On the other hand, the greatest yield was found with the mushrooms grown on the medium containing 1.5 kg soybean powder, 0.75 kg yeast powder and 0.2 kg ammonium sulfate, with an average of 3.76 kgm-2, which was a 9.62% increase over the control.There were significant differences on the yields among different strains of A.Blazei Murrill.For instance, A5 and A6 grew the fastest, averaging a daily growth rate of 0.29 cm; and, A8 had the highest yield of 3.42 kgm-2.This cultivation practice appeared to have a potential for wide application that could lessen the burden of competing for raw materials between A.Blazei Murrill and A.Bisporus cultivations, reduce the cost of cultivating edible fungi, improve the biological efficiency of composting and waste recylcling, and improve the profibility of the mushroom farming.
