利用虎杖药渣栽培杏鲍菇的培养基优化及菌糠再利用分析

为了达到资源化的最大利用，实现节能减排、发展生态经济，以虎杖药渣作为常规培养基新的添加成分对杏鲍菇进行熟料法袋栽试验，采用正交设计9个不同组合配方对新的培养基进行优化。结果表明：优化后的最佳培养基配方为虎杖药渣的含量为55 kg，棉籽壳含量为20 kg，木屑的含量为20 kg，麦麸的含量为15 kg，白糖1%，石膏1%。对栽培杏鲍菇后最佳培养基的菌糠成分做了测定：菌糠中含有较高比例的脂质，蛋白质，分别为6.20%和8.94%；另外其中重金属含量均低于国家有机肥标准中的规定，表明虎杖渣熟料法栽培杏鲍菇后的菌糠在有机饲料及生物有机复混肥的生产中还有再次利用的价值；通过高效液相色谱仪检测出杏鲍菇子实体中白藜芦醇的含量为4.91 μg/g。

Use of Polygonum cuspidatum Cultivation of Pleurotus eryngii Cultivation Medium Optimization and Recycling of Mushroom-planted Analysis

In order to optimize the allocation of resources, the bio-experiment of culturing Pleurotus eryngii, adding polygonum cuspidatum as the substrate, used 9 formulas to optimize the new substrate. The result of the experiment showed that, the best formula of substrate includes 55 kg of polygonum cuspidatum, 20 kg of cottonseed hull, 20 kg of wood chips, 15 kg of wheat bran, 1% of white sugar and 1% of gypsum. This paper concluded that the mushroom-planted consists of 6.20% of lipid and 8.94% of protein. According to the national standard of organic fertilize, the content of heavy metal in the waste medium was under the national level, which showed that the waste medium by adding polygonum cuspidatum to culture the Pleurotus eryngii could be recycled in the organic feeds and biological organic fertilizer. As the HPLC shows, the content of resveratrol in the fruiting body was 4.91 μg/g.
