Abstract:

In this research, we studied the most suitable formula and preparation techniques of Stropharia rugoso-annulata cultivation in the sunlight greenhouse by using peach sawdust and corn agricultural waste from Pinggu in Beijing. This article set up 3 preparation and 6 formulas, and comprehensively compared the agronomic traits such as physical and chemical traits, fruiting traits, average yield and biological efficiency. We find that raw materials are significantly superior to fermentation materials in agronomic characters and yield. Fermentation material + short time high temperature is slightly better than fermentation material in yield and agronomic characters. In raw materials, the maximum yield of S-1 (peach sawdust and corn cob) formula is 11.97 kg/m², its biological efficiency is 99.75%, and its fruit body traits are excellent. The formula of S-2 (peach sawdust and corn straw) is the best in fruiting body characters, such as mushroom shape index and weight of single mushroom, the time from sowing to fruiting is short, and the yield and biological efficiency are also high. The multi-material mixing of S-3 (peach sawdust, corn stalk and corn cob) is conducive to the formation of early yield. The raw material cultivation techniques of these three formulas are all suitable for the cultivation of Stropharia rugoso-annulata in Beijing. This paper could provide technical support for popularizing and cultivating Stropharia rugoso-annulata and using peach sawdust resources in Pinggu of Beijing.
