摘要: 为提高水稻秸秆资源利用效率,研究了在水稻秸秆中添加稻壳、木屑等辅料对大球盖菇的生长及秸秆降解的影响。结果表明,添加木屑促进了大球盖菇菌丝的生长,子实体鲜重和生物学效率提高了10.0%,原料消耗率提高了8.8%。添加稻壳也促进了大球盖菇菌丝的生长,子实体鲜重和生物学效率提高了15.7%,原料消耗率提高了13.1%。添加木屑和稻壳分别使纤维素降解率提高了9.9%和11.5%。水稻秸秆种植大球盖菇后,秸秆中有机碳、氮、磷含量降低,而钾含量增加,添加稻壳对秸秆碳、氮、磷、钾含量变化没有显著影响,添加木屑显著降低了秸秆磷、钾含量。综上所述,添加木屑、稻壳提高了水稻秸秆的降解,促进了大球盖菇的生长。

Abstract: To improve the utilization efficiency of rice straw resources, the effects of addition of rice husk and sawdust on the growth of Stropharia rugoso-annuata and straw degradation was studied. The results showed that the addition of sawdust promoted the growth of mycelia of Stropharia rugoso-annuata, increased the fresh weight and biological efficiency of fruiting body by 10.0%, and increased the consumption rate of raw materials by 8.8%. The addition of rice husk also promoted the growth of mycelia of Stropharia rugoso-annuata, increased the fresh weight and biological efficiency of fruiting body by 15.7%, and increased the consumption rate of raw materials by 13.1%. After planting the mushroom, the cellulose degradation rate of rice straw was 51.2%, that of sawdust and rice husk treatment increased by 9.9% and 11.5% respectively.The content of organic carbon, nitrogen and phosphorus in straw decreased, but the content of potassium increased. The addition of rice husk had no significant effect on the content of carbon, nitrogen, phosphorus and potassium in straw. The addition of sawdust significantly reduced the content of phosphorus and potassium in straw. In conclusion, the addition of sawdust and rice husk can promote the growth of Stropharia rugoso-annuata and improve the degradation of rice straw.

Key words: rice straw, Stropharia rugoso-annulata, rice husk, sawdust, degradation
