Prepare fully ripened biogas residue and cover it with a film to prevent insects from spawning on the biogas residue and drain for 24 hours. Select a fresh, mildew-free cotton shell and turn it over for 1-2 days.

Ingredients are 60% of biogas residue, 40% of cotton husk, or 70% of biogas residue, 30% of cotton husk. First mix the cotton husk with water wet, then mix well with the biogas residue. The water content is pinched by water droplets, but it is not suitable for dropping.

Mushrooms are selected for indoor or outdoor ventilation. If the floor is upstairs, plastic film is used for the bottom of the bed. The width of the bed is 80-100 cm. The length depends on the site and the thickness is 6-8 cm.

Seed sowing with 4 kg per 100 kilograms of cultivated material, strains should be full of mycelium, free from bacteria, and preferably no more than one month old. Press 6 cm 6 cm to see the hole, hole depth 3 cm, a hole in the size of a species of beans, after sowing with plastic film insulation, moisturizing.

Before the mushrooming management, it is necessary to seal the plastic film, and generally remove the film and air 1 time every 7 days. Pleurotus ostreatus requires more water and oxygen consumption during the formation of fruit bodies. At this time, attention should be paid to ventilation and supplementary water.

The harvesting of fruiting bodies can be harvested when the fruiting body grows up to eight. Premature harvesting will affect the yield, too late harvest will reduce the quality, the first batch of Pleurotus ostreatus after harvest, after 15-20 days can grow into the next batch, generally after a batch of material bed inoculation can harvest three or four batches Pleurotus.

Topdressing nutrient solution with a wooden stick to play 2 cm deep hole, into the nutrient solution. The nutrient solution can be 0.1% urea solution.
