不同配比苹果果渣栽培秀珍菇试验

Study on Different Ratios of Apple Pomace for Cultivation of Pleurotus geesteranus

以秀珍菇为试材,采用不同比例的苹果果渣替代木屑,以熟料袋栽方式进行秀珍菇栽培试验。对不同配方的菌丝生长速度、生物学效率、投入产出比和经济效益等指标进行统计分析。结果表明:若将各配方污染菌包成本包含在内,以总产量为评价指标,则配方G3(苹果果渣60%、木屑20%、麦麸18%、石膏1%、石灰2.5%、料水比1∶1.9)的净利润和投入产出比(1∶2.37)最高,栽培成本比对照(G0)降低17.93%,经济效益提高7.40%;若不考虑污染菌包的成本,以单袋产量为评价指标,则配方G3的生物学效率最高(76.27%)、栽培成本比全木屑降低39%以上,经济效益比对照提高3.37%;综合评价,配方G3为苹果渣栽培秀珍菇的最适配方,其替代木屑的最大用量为60%。

Taking Pleurotus geesteranus as test material,the cultivation of Pleurotus geesteranus in bag was made by using different ratios of apple pomace to replace saw dust.The indexes of mycelia growth speed,biological efficiency,input-output ratio,economic efficiency,and so forth,was statistical analyzed.The results showed that with total yield as the evaluation index,the formula G3（pomace 60%,wood chips 20%,wheat bran 18%,gypsum 1%,lime 2.5%,sub strate to water 1∶19）had the highest net profit and input-output ratio（1∶2.37）,the cultivation cost reduced 17.93%than that in control（G0）,and economic benefit was increased by 7.40%,if to include the cost of pollution fungi bags.However,the formula G3 had the highest biological efficiency（76.27%）,the cultivation cost was reduced more than39%,and the economic benefits was increased by 3.37%compared with the control,if no pollution fungi bags cost had been in considered and with a single bag production as the evaluation index.Comprehensive evaluation,the formula G3 was suitable for the cultivation of Pleurotus geesteranus with apple pomace,and the maximum dosage to replace sawdust was 60%.
