Key words:  dregs of R.polygonatum  P.citrinopileatus  Hericium erinaceus

摘要:

[目的]筛选出适合以黄精浸渣为主料（60%以上）栽培的食用菌品种，并确定相应的高产栽培配方。[方法]在含60%黄精浸渣的菌包上接种不同品种的食用菌，对比其菌丝生长和出菇情况，筛选出适应性较好的食用菌；以不同黄精浸渣含量的配方进行栽培，通过对生物转化率和利润率的比较，筛选出最佳配方。[结果]配方3栽培榆黄蘑T2的平均生物转化率达到136%，平均利润率为72%；配方2栽培猴头一号的平均生物转化率达到105%，平均利润率为70%。[结论]榆黄蘑T2和猴头一号能健康地消化利用黄精浸渣，并带来较好的经济效益。

Abstract:

[Objective] In this study,we used the dregs of the Rhizoma polygonatum to grow edible fungus. The aim was to select edible fungus strains which were suitable for using the dregs of the Rhizoma polygonatum as the main material (more than 60%),and to determine the high yield cultivation formula by the mushroom test.[Methods] Cultivating different edible fungus strains on medium containing 60% R.polygonatum residue, the strains with better adaptability were screened out by comparing the growth of mycelia and the fruiting condition. The cultivation was carried out with different formulas of dregs of R.polygonatum residue content, and the best formula was selected by comparing the biological efficiency and the profit rate.[Results] The average biological efficiency of formula 3 cultivated Pleurotus citrinopileatus T2 reached 136%, and the average profit margin was 72%.The average biological efficiency of formula 2 cultivated Hericium Ⅰ reached 105%, and the average profit margin was 70%.[Conclusion] P.citrinopileatus T2 and Hericium Ⅰ can digest and utilize the dregs of R.polygonatum safely, and bring better economic benefits.
