How to ingredient edible fungus with fermentation auxiliaries?
Edible fungus culture material is a very important part of affecting the growth and development of edible fungi, so how to make a very good culture material?
Material preparation: prepare edible mushroom culture material fermentation aids according to 0.1% of the culture material weight (that is, 1/1000, if the newspaper waste is reused, 0.2% can be added); soak or pre-wet the crushed or cut off main materials in advance, adjust the moisture to 60%, 70%, and the PH value is about 8.
Mixing: diluting the fermentation auxiliaries with fresh rice bran (poor nutrition of old rice bran, disadvantageous) (adding 5 kilograms of rice bran for every 1 kg of fermentation auxiliaries), and then mixing the diluted fermentation auxiliaries with pre-wetted wheat bran, cake fertilizer, manure and other auxiliary materials, and then evenly mixed into the main material.
Heap: mix the culture material evenly and stack it according to the routine. The pile is evenly perforated and ventilated with pointed rods about 10 cm in diameter, and covered with sacks, straw curtains and other breathable coverings for heat preservation and moisturization.
Tipping: when the temperature of the material rises to about 65 ℃, it can be tipped for the first time, and then tipped again in 4 days, and the tipping interval of Pleurotus ostreatus is slightly longer.
Temperature control: at the initial stage of fermentation, it is normal for the temperature to rise rapidly to more than 70-75 ℃, but it should be turned over immediately, and the high temperature of more than 75 ℃ should not be maintained for a long time, otherwise it will cause great loss of nutrients and affect the yield. In the later stage, according to the different temperature requirements of different kinds of edible fungi, measures were taken to control the temperature in an appropriate range, such as removing mulch, increasing drilling density, replenishing water, reducing pile height, tipping and so on.
Humidity control: with the sharp increase of stack temperature and the continuous accumulation of heat, a large amount of water in the material will evaporate and lose, so while overturning, water should be replenished in time according to the specific situation (0.5% raw lime water is better). The last replenishment and turning of the pile should be completed at the same time, sowing should try to avoid the addition of "unboiled water", so as not to cause the bacteria "do not eat" after sowing.
Completion: Pleurotus ostreatus, straw mushroom and other mushroom culture materials need to be fermented for about 5-6 days, and bisporal mushrooms need about 10-15 days. The fermented and mature culture material, the moisture is about 65%, is generally brown, the surface is covered with white hyphae, has no ammonia flavor and has fragrant smell, is not sticky and elastic, and the straw is broken by light pulling, indicating that the fermentation is complete.
