桑枝屑栽培金福菇配方对比试验

【目的】对桑枝屑不同添加配比对金福菇产量、效益的影响进行研究，以筛选出金福菇最适桑枝屑栽培配方，为实现桑枝条资源化利用和食用菌高产优质栽培提供依据。【方法】以传统的甘蔗渣、棉籽壳、麸皮培养基配方为对照，设计4个以桑枝屑为主料、麸皮为辅料的培养基配方，通过制作菌袋、脱袋覆土、出菇管理与采收等环节，比较各配方金福菇的产量、生物学效率及投入产出比。【结果】利用桑枝屑为主料栽培金福菇，各配方均能正常出菇，但金福菇的产量与桑枝屑、麸皮的配比有关；配方③（桑枝屑80％，麸皮17％，糖、石膏、磷肥各1％）的鲜菇产量、生物学效率及投入产出比均最高，其余配方金福菇的生物学效率虽不及对照，但投入产出比均高于对照。【结论】利用桑枝屑为主料栽培金福菇可以降低生产成本，提高生产效益，适宜在广西桑蚕主产区大力推广应用。但生产上需注意培养料的碳氮比，以实现食用菌优质、高产栽培。

Comparison of Tricholoma lobayense Heim culture formula ingredients using different mulberry sawdust ratios

[Objective]The aim of this study was to optimize the ingredients concentration in culture media used to grow Tricholoma lobayensc Heim with mulberry sawdust for resource utilization and high yield cultivation, and the yield and benefits were analyzed based on addition of different quantities of mulberry sawdust. [Method] The yield, biological efficiency, and input-output ratio were compared among different treatments. The treatments consisted of four different quantities of mulberry saw dust mixed with auxiliary material and wheat bran. The control （CK） culture medium contained the traditional ingredients including bagasse, cotton seed hull and wheat bran. [Results]The result showed the practicable utilization of mulberry sawdust as the staple materials for the cultivation of T. lobayense, however, the yield was found related to the ratio of mulberry sawdust and wheat bran in the culture formula. The highest yield and biological efficiency and the best input-output ratio were found in the treatment containing 80% mulberry sawdust, 17% wheat bran, sugar, gypsum and 1% calcium superphosphate. The biological efficiency of the other treatments was not found higher than the control, however, the input-output ratio were higher compared to control. [Conclusion]Utilization of staple materials with mulberry sawdust for the cultivation of T. lobayense Heim not only reduced the production costs, but also improved production efficiency, The technique was found suitable for popularization and application in silkworm production areas in Guangxi.
