摘　　要：为提升秀珍菇的工厂化生产水平,试验测定了不同碳源及氮源条件下秀珍菇的菌落直径、菌丝长势等,研究了不同碳源及氮源对秀珍菇菌丝生长的影响。结果表明:秀珍菇具有较广的碳源及氮源,在可溶性淀粉、葡萄糖、麦芽糖、蔗糖这4种不同的碳源中,秀珍菇菌丝均能生长,以葡萄糖为碳源时,秀珍菇的菌落长势最好,其次是蔗糖、麦芽糖、可溶性淀粉,在以葡萄糖、蔗糖、麦芽糖、可溶性淀粉为碳源的培养皿中第12天时秀珍菇的菌落直径分别为42.53、39.98、35.63、31.46mm;在以尿素、蛋白胨、酵母粉和硫酸铵这4种不同的氮源中,秀珍菇菌丝均能生长,以蛋白胨为氮源时秀珍菇菌落长势最好,其次是酵母粉培养基,以尿素与硫酸铵为氮源的培养皿菌落长势差异不大。In order to promote the industrialized production of Pleurotus geesteranus,the colony diameter and hypha growth of different carbon source and nitrogen source under the condition of Pleurotusgeesteranuswere measured in this experiment and the effects of different carbon and nitrogen sources on the mycelial growth of Pleurotus geesteranus were analyzed.The results showed that Pleurotus geesteranus had wide carbon source and nitrogen source.In the soluble starch,glucose,maltose,sucrose 4 different carbon sources,Pleurotus mycelium could grow with glucose as carbon source,the colony growth of Pleurotus geesteranus was the best,followed by sucrose,maltose and soluble starch on twelfth days,in a petri dish with glucose,sucrose,maltose and soluble starch as the carbon source colony diameter of Pleurotus geesteranus were 42.53,39.98,35.63,31.46 mm,respectively.In urea,peptone,yeast powder and ammonium sulfate 4 different nitrogen sources,the mycelium of Pleurotus geesteranus could grow,and with peptone as nitrogen source colony growth of Pleurotus geesteranus was the best,followed by the yeast culture medium,with urea and ammonium sulfate as the nitrogen source colony growth difference was not significant.
