| Abstract: In order to make full use of the resources of ecological forest land, branches and straws, the
cultivation experiment of Stropharia rugosoannulata was carried out under the ecological forest in Beijing
Fangshan district. Cultivation experiments were conducted in outdoor cultivation mode (M1) and sunshade net
cultivation mode (M2) by using corn cob and sawdust as main materials, and three formulas were designed. The
mycelium growth vigor, biological efficiency, commercial fruit body rate, input and output were compared and
analyzed. The results showed that the mycelium in formula F3 (mixed sawdust 64%, corn cob 30%, wheat bran
4%, lime 2%) was strong, the biological efficiency was highest with 47.23%, the commercial fruit body rate was
highest with 79.37%, the cost of commercial fruit body was lowest with 4.34 yuan/kg. In cultivation mode M1, the
biological efficiency of the three formulas was 18.64 %, 21.44 % and 23.87 % higher than that of cultivation mode
M2, respectively, the commercial fruit body rate increased by 25.96 %, 17.80 % and 16.32 %, respectively, and
the cost of unit commercial fruit body decreased by 23.33 %, 19.17 % and 19.62 %, respectively. In summary, the
formula F3 and cultivation mode M1 had obvious advantages, which could be combined to optimize and promote
applications according to the local resources. |
