Mushrooms have requirements for growth environment, so to prepare a mushroom farm, you can choose a gentle slope with good resources, close water source, shade, gravel and acid as a mushroom farm.

Step 2 prepare bag materials

The raw materials of the bag material can be hardwood sawdust, some needle sawdust, shavings, paper scraps, cottonseed hulls, waste cotton, beet dregs, rice straw, corn stalks, corncobs, wheat straws, sorghum hulls, peanut hulls, chaff and the like. Then, according to the formula, it is made into culture material. The commonly used formula is sawdust 78%, wheat bran 20%, sugar 1%, gypsum 1%, water 120- 125 kg and carbendazim 0. 1%. Sterilize the culture material at the high temperature of 98- 100℃ 10- 12 hours, and then inoculate fungi after cooling.

3. Seed strain

When sowing mushroom strains, mix 2/3 of the strains and culture materials evenly, sow in plastic film, sow 1/3 of the strains on the ground, and compact to make the mushroom bed flush with the ground. Put the straw on the bed surface, then cover it with plastic film, and then cover it with 5- 10cm thick soil.

4. Daily management

More than 50 days after sowing, hyphae can grow all over the mushroom bed. At this time, it is necessary to wrap it in time, remove the soil covered on the plastic film, open the plastic film, remove the straw, cover the plastic film, and immediately arch the curtain and keep it for 7- 10 days to promote the growth of mycelium. 7- 10 days after packaging, open the straw curtain, open the plastic film and ventilate every morning and evening. Sponge up the accumulated water in the bed area in time, remove the diseased block, do a good job of disinfection, and cover with plastic film and straw curtain after ventilation for 2 hours to promote the discoloration of hyphae. Generally, the color change period lasts for more than 20-30 days, and the bed surface turns to brown fungus skin to enter the fruiting period.
