桑枝屑夏季栽培秀珍菇的配方优化

【目的】筛选以桑枝屑为原料、适合秀珍菇夏季栽培的最佳配方,为实现桑枝条资源化和秀珍菇反季节高产优质栽培提供参考依据。【方法】利用＂移动式菌棒制冷＂工艺对菇棚进行降温刺激,以不同添加比例的桑枝屑（90%、85%、80%）为原料配制成3个栽培配方,以玉米芯添加麸皮的配方作对照,比较各配方栽培秀珍菇的菌丝生长情况、鲜菇产量、生物学效率、经济效益及氨基酸含量。【结果】不同桑枝屑添加配比的栽培配方在夏季栽培秀珍菇均能正常出菇,但对秀珍菇菌丝生长、鲜菇产量、生物学效率及氨基酸含量的影响不同,综合考虑,以桑枝屑80%、麸皮18%、碳酸钙1%、石灰1%为配方进行秀珍菇夏季栽培的效果最佳,其菌丝长势好,平均每袋鲜菇产量、生物学效率、投入产出比和氨基酸总量均最高,分别为0.48 kg、111.6%、1∶2.57和4.24%。【结论】利用＂移动式菌棒制冷＂工艺,以桑枝屑为主料添加麸皮、碳酸钙、石灰的配方在夏季栽培秀珍菇是可行的,既可降低生产成本,又具有较好的经济效益。

Formula optimization of Pleurotus geesteranus summer cultivation using mulberry sawdust

【Objective】The best formula of Pleurotus geesteranus cultivating in summer with mulberry sawdust as raw material was screened to provide references for anti-season and high-yield of Pleurotus geesteranus. 【Method 】Using the technology of moving edible-fungus pack refrigeration to lower the greenhouse temperature, three different treatments of mulberry-sawdust packs（90%,85%,80%） were designed with the formula of bran and corncob as the control to assay hypha growth, yield, biological efficiency and amino acid content. 【 Result 】 Pleurotus geesteranus in three different proportion of mulberry-sawdust packs grew normally, but hypha growth, yield, biological efficiency and amino acid content were different. All things considered, the formula of 80 % mulberry-sawdust, 18% bran, 1% calcium carbonate and 1% hydrated lime was the best, in which yield per bag, biological efficiency, input-output ratio and amino acid content reached the maximum, which was 0.48 kg, 111.6%, 1∶2.57 and 4.24%, respectively. 【Conclusion 】Using the technology of moving edible-fungus pack refrigeration, the formula of mulberry-sawdust, bran, calcium carbonate and hydrated lime is workable because of its cost reduction and good economic benefits.
