本研究以大球盖菇Stropharia rugosoannulata为研究对象,针对秸秆资源开展基料化还田技术研究.培养料配方设置了六个处理,试验结果表明,玉米秸秆是大球盖菇最好的生产材料,发菌快、出菇早.玉米秸秆培养料中适量增加锯末,有利于种菇后菌糠有机质和全氮的增加与积累,而葵花秸秆配方不适合作为过菌还田改良土壤.纯玉米秸秆作为培养料种菇省水、保水,而葵花秸秆作为培养料水分消耗较多,因此使用葵花秸秆开展大球盖菇生产,需加大菇床水分供应.
This study focuses on Stropharia rugosoannulata as the research object,and conducts research on the technology of returning straw resources to the field through substrate conversion.Six treatments were set up for the cultivation material formula,and the experimental results showed that corn straw is the best production material for Stropharia rugosoannulata,with fast growth and early emergence.Adding sawdust to the corn straw culture medium in an appropriate amount is beneficial for the increase and accumulation of organic matter and total nitrogen in the mushroom bran after mushroom cultivation,while the sunflower straw formula is not suitable for soil improvement through microbial return.Pure corn straw is used as a cultivation material to cultivate mushrooms,which saves and preserves water,while sunflower straw consumes more water.Therefore,using sunflower straw for the production of Stropharia rugosoannulata requires increasing the water supply of the mushroom bed.
