Abstract: There are a huge amount of spent mushroom substrates (SMS) in China, meanwhile, there is a huge market demand for horticultural substrate. Therefore, utilizing SMS as horticultural substrate is of great significance. SMS has great potential for substrate utilization as it has unique physical and chemical properties, as well as rich nutrients. However, the substrate utilization of SMS is still insufficient. In view of this situation, this paper summarized the main problems existing in the substrate utilization of SMS, including the physicochemical properties of SMS varied greatly, while the research on uniformization technique was weak; the electrical conductivity (EC) value of SMS was generally high, while efficient salt-reduction technology was lack; the existing substrate utilization technology of SMS was mainly through fermentation, which failed to fully utilize the potential of SMS. This paper also put forward some countermeasures for substrate utilization of SMS, with the purpose to provide guidance for efficient substrate utilization of spent mushroom substrates.
