The invention discloses a joint cultivation method for mulberry silkworms and fungi. The joint cultivation method includes breeding the mulberry silkworms by the aid of mulberry leaves; preparing strain nutrients from mulberry branches and silkworm manure; uniformly spreading the strain nutrients on fungus beds and nourishing strains; adding water to the fungus beds to guarantee appropriate humidity of the fungus beds. The joint cultivation method has the advantages that lentinula edodes planting and the silkworm mulberry industry are successfully combined with each other, mulberry resources can be sufficiently utilized, the mulberry silkworms can be bred by the aid of the mulberry leaves, the mulberry branches and the silkworm manure can be used for cultivating the fungi, accordingly, themulberry resources can be utilized to the greatest extent, the joint cultivation method can be locally implemented, and the raw material transport cost can be saved; the fungi can be cultivated in mulberry fields, the mulberry silkworms can be bred in the mulberry fields, accordingly, mulberry silkworm breeding waste and land resources can be effectively utilized, the production cost can be reduced, and the social benefit and the ecological benefit can be increased.
