金针菇松杉木屑菌糠栽培猴头菇的技术研究

为降低猴头菇生产成本和解决松杉木屑工厂化栽培金针菇菌糠利用问题,研究了金针菇菌糠营养成分和不同配方对猴头菇产量及经济效益的影响。结果显示:金针菇菌糠含有9.8%粗蛋白、32.3%粗纤维、1.2%粗脂肪、17.9%木质素和7.7%灰分;筛选出配方2是最佳的配方,比例分别为金针菇菌糠38%、棉籽壳20%、玉米芯30%、麸皮10%、碳酸钙2%,其产量和利润分别比对照组、配方1、配方3和配方4提高了9.67%、25.00%、6.12%、8.40%和115.91%、48.44%、46.15%、25.00%。为金针菇菌糠用于猴头菇大面积栽培提供了科学依据。

Cultivation Technology of Hericium erinaceus Using Pine and Chinese Fir Sawdust-derived Spent Compost of Flammulina velutipes

To reduce the production cost of Hericium erinaceus and to better utilize spent substrate of Flammulina velutipes produced from factory cultivation with mixed sawdust of pine and Chinese fir as the mainly ingredients,the composition of the spent was determined and its utilization for H.erinaceus cultivation was evaluated.The results showed that the spent consisted of 9.8％ crude protein,32.3％ crude fibre,1.2％ crude fat,17.9％ lignin,and 7.7％ ash.The formula 2 consisting of 38％ spent substrate,20％ cottonseed hull,30％ corn cob,10％ wheat bran,and 2％ calcium carbonate was optimal for H.erinaceus production,which gave mushroom yield improvement of 9.67％,25.00％,6.12％,and 8.40％,and profit increase of 115.91％,48.44％,46.15％,and 25.00％,respectively as compared with those of the control,formula 1,3,and 4.The present study provides scientific base for H.erinaceus cultivation using the pine and Chinese fir sawdust speut substrate after F.velutipes cultivation.
