松杉木屑原料易得,成本低廉,但因其含有对食用菌生长有害的物质,不能用于食用菌栽培.本文介绍对松杉木屑脱毒技术要点:①翻晒:将新鲜松杉木屑翻晒2～3天至干燥.②浸泡:将干木屑放在大缸(盆)中,加入沸水(浸没物料)和1%～2%石灰水(pH12),加盖棉絮等保温2～3天,捞起用清水漂洗至无松油味和碱味.③发酵:将洗净的木屑控水至60%～70%,pH7左右;堆积覆膜进行自然发酵,料温保持在65～69℃,2～3天即可散开堆料,用于食用菌栽培.
Pine fir sawdust raw materials easily available, low cost, but because it contains harmful substances on the growth of edible fungi, can not be used for mushroom cultivation.This article describes the pine fir sawdust detoxification techniques: ① drying: fresh pine fir sawdust 2 ~ 3 days to dry. ② soaking: the dry wood chips on the tank (basin), add boiling water (immersion material) and 1% ~ 2% lime water (pH12), stamped with cotton insulation 2 to 3 days, fishing From rinsing with water rinse until no loose oil smell and base flavor.③Fermentation: the washed wood chips water control to 60% ~ 70%, pH7 or so; deposited film for natural fermentation, the feed temperature maintained at 65 ~ 69 ℃, 2 ~ 3 days to spread the pile, for mushroom cultivation.
