Cultivation mode,artificial log made techniques,main supplement cultivation substrate,strain and growth development factor were researched in order to reduce consumption of broad-leaf tree and reach the objection of saving sawdust,high yield,high quality and excellent efficiency in Lentinula edodes cultivation.High quality and excellent efficient sawdust-saving cultivation techniques for Lentinula edodes was summarized.In contrast to route techniques that made broad-leaf tree sawdust as main cultivation substrates,the techniques can save broad-leaf tree sawdust 50%~67%,increase excellent rate of artificial log after inoculation sterilization 12%~20%(reached 95%),save 50% fuel for sterilization,reduce abnormal fruit-body deeply,increase high quality fruit-body that reach export standard 20%,increase solidity of artificial log and decrease rotten bag rate.
