I. Common formula for cultivation of straw mushrooms

Formula 1: 88% waste cotton, 10% straw, 2% lime.

Formula 2: 83% straw, 15% dry cow dung, 2% lime.

Formula 3: 78% enoki mushroom residue, 20% straw, 2% lime.

II. Pre-fermentation of culture medium

Take the commonly used formula 1 as an example, fully pre-wet the waste cotton, cut the straw into 5~10 cm and pre-wet it, add 0.5% lime water and mix it, and turn the pile to make its water content reach 70% and pH 9; shovel out the pre-wetted waste cotton and drain the water, and then mix the waste cotton with the pre-wetted straw and 1.5% lime evenly. Pile the culture medium into a pile with a height of 0.7~1 meter, a width of 1.2~1.5 meters, and a length arranged according to the actual production volume; the above culture medium pile is turned every other day and can be put into the mushroom house on the third day.

3. Post-fermentation of culture medium

In principle, the culture medium that has undergone pre-fermentation can be directly inoculated, but if conditions permit, it is best to undergo post-fermentation. The role of post-fermentation: First, it kills harmful microorganisms and pests in the culture medium more thoroughly; second, through the action of thermophilic microorganisms, the culture medium becomes selective, which is conducive to the growth of mycelium of straw mushrooms, but not conducive to the growth of mycelium of other fungi.
