為向本省菇農推薦杏鮑菇瓶栽自動化生產最適與最經濟之米糠用量,遂進行本試驗研究。研究結果顯示,當基質內之米糠量由0增至47.95%時,杏鮑菇ATCC 36047品系之產量、生物與產菇效率均隨米糠量增加而顯著提高;至於Holland 150品系之生物與產菇效率則當米糠填加至38.08%時,達到最高,若米糠量增至47.95%時,則反而顯著下降。此結果顯示不同杏鮑菇品系對米糠填加量之反應不同,其中ATCC 36047品系較Holland 150品系需要更多米糠之某種成份以發揮其最大之生物與產菇效率。考量杏鮑菇栽培庫之容量、每瓶栽培用菌種之生產力及杏鮑菇之生產成本,杏鮑菇瓶栽自動化生產時最適及最經濟之基質米糠建議使用量,對ATCC 36047及Holland 150兩品系分別為約基質乾重之48%與38.08%。
The effect of rice bran supplementation on the production of two king oyster mushroom strains was investigated in order to recommend the optimum and economic amount of rice bran for growing the mushroom to Pleurotus mushroom growers in Taiwan. The average yield, biological efficiency (B.E.) and production efficiency (P.E.) of the strain ATCC 36047 increased significantly with the supplementation of rice bran to substrate from 0 to 47.95% by weight of dry matter. The B.E. and P.E. of the strain Holland 150 reached the highest level when the rice bran was added up to 38.08%, but decreased significantly when the supplementation was up to 47.95%. These results show that different king oyster mushroom Strains response differently to the supplementation amount of rice bran and might indicate that the strain ATCC 36047 necessitate a great supply of some ingredients in rice bran to increase its B.E. and P.E. In consideration of the capacity of cropping room, productivity of cultivation spawn and mushroom production cost the most optimum and economic amout of rice bran in substrate would be about 48% and 38% for the strains ATCC 36047 and Holland 150 respectively..
