The purpose of the present invention is to provide a technique for cultivating mushrooms that can considerably reduce waste material produced after cultivation, and that can recover and reuse a culture substrate after cultivation. Mushroom cultivation is made possible when a culture medium for cultivation is used, the culture medium for cultivation being impregnated with water and a nutrient source using a reusable fiber substrate as a culture substrate. Furthermore, the culture substrate can be easily recovered after cultivation, and the culture medium can be washed in a simple manner using an existing washing device and reused as a culture substrate, and is capable of considerably reducing waste material produced by mushroom cultivation.本發明提供一種菇類栽培技術,其目的在於可在栽培後簡便回收培養基材再利用,而可大幅減低栽培後產生的廢棄物。若將可再利用之纖維基材用作培養基材,並使用令其含浸有水與營養源之栽培用培養基,則可進行菇類栽培。再者,該栽培用培養基可於栽培後容易地回收培養基材,且可使用既存之洗淨裝置簡便洗淨後便再利用為培養基材,而可大幅減低菇類栽培所產生的廢棄物。
