The effect of facility based substitute cultivation of sorghum straw on the yield and quality of Lentinula edodes
Lentinula edodes is an important edible and medicinal wood-decaying fungus.In the context of the increas-ing scarcity of forestry resources,it is very important to explore suitable alternatives to support the sustainable develop-ment of shiitake mushroom industry.This study conducted a facility based experiment to cultivate shiitake mushroom with different proportions of sorghum straw replacing part of sawdust,and selected the optimal ratio to achieve the bal-ance of yield and quality by measuring the total sugar,lignin,cellulose,calcium ion,phosphorus ion and pH of the shii-take mushroom stick and protein,total sugar and yield of the shiitake mushroom fruit body.The results showed that sor-ghum straw replacing part of sawdust could produce normal mushrooms and significantly increase the yield.When 15％sawdust in the sticks was replaced by sorghum straw,the yield increase was the most significant,with the average yield of each stick reaching about 1.65 times of that of a normal stick,and the quality of shiitake mushroom at this ratio was also improved to a certain extent.These results indicate that sorghum straw has good economic and utilization value in the facility based industry of shiitake mushroom alternative cultivation.
