Cultivation of Coprinus comatus with high yield in distillers' grains

Distillers grains are a good raw material for mushroom cultivation. Its nutrient composition is suitable for the growth of mycelium such as Coprinus comatus, which can not only reduce the cost of mushroom production, but also solve environmental pollution. Distillers grains contain a small amount of ethanol and active yeasts that are harmful to the growth of mycelia. The acidity is large, and the pH is about 3 to 5. Fresh distiller's grains were used, together with other items, formula: 1, 90% distiller's grains, 8% lime, 1% gypsum, 1% ammonium bicarbonate, biological efficiency of 120% to 130%. 2, 39% distiller's grain, 39% corn cob, 10% rice bran, 8% lime, 2% gypsum, 1% superphosphate, 1% ammonium bicarbonate, biological efficiency 130%. 3, 50% distiller's grains, 30% cotton, 8% bran, 8% lime, 2% gypsum, 1% superphosphate, 1% ammonium bicarbonate, biological efficiency 130%. 1. Mix the lime, gypsum and ammonium bicarbonate directly into the distiller's grains, adjust the PH value to 9-11, and prepare other materials (cotton skin, corn cob) according to the formula of oyster mushroom and coprinus comatus, and evenly stir in the distiller's grains. Fermentation for 5 hours to 8 hours, spread out after the cool air bagging. Mixing must be uniform, PH value must be increased to 9 to 11 in the early stage. Second, the selection of high-quality, high-yield strains and the use of high-quality cultivar strains are the prerequisites for high yield, high-yield preconditions, and good strains have strong viability, strong ability to disintegrate the matrix, rapid mycelial growth, and adaptability Wide, strong resistance, high rate of adult mushrooms. 3. After bagging and seeding, a 5026-polyethylene bag is selected and a layered seeding method is adopted. That is, the three-layered material is four-layered, and the two ends of the bag are evenly laid apart, and the middle two layers of bacteria closely adhere to each other. On the outside of the plastic bag, 3 to 4 eyes are hand-sewn on each bacterial seed block after filling the bag for ventilation. According to the temperature determined by the number of bags, the best temperature during the germination period is 23°C～26°C, the temperature of the mycelium grows fastest, and it is not suitable for the growth of the bacteria. For the sake of safety, the germination temperature is preferably lower. It does not hinder the growth of mycelium, but also inhibit the growth of bacteria. Fourth, fruiting period management After 30 days to 35 days of germination period, you can carry out fruiting period management, shed Yangshuo to advance sterilization and pest control, in advance with 2% of the formaldehyde and 1% dichlorvos mixed liquid heap stuffy Cover the soil for 24 hours, then add 2.5 kg of lime, 2.5 kg of plant ash, and 1 kg of phosphate fertilizer every 2 inches of soil. Remove the film of the coprinus comatus or oyster mushroom bag from the good bacteria and lay it in Yangshuo. Cover it with a piece of soil. The thickness is about 4 cm. Then spray a heavy water and cover a small arch. During this period, pay attention to the space humidity and temperature. The adjustment, coprinus comatus in a suitable temperature for the mushroom period of 13 °C ~ 26 °C, the space humidity is about 85%, after about 10 days out of the soil surface grows aerial hyphae, to be regularly ventilated, while spraying, spraying water The principle is less, light spray, can not be directly after the emergence of fruiting body water, this time to increase the space humidity, and enhance ventilation, ventilation before the mushroom room to spray. Practice has proved that in the specific management of watering of the fruiting period, the buds should be prohibited from spraying, and the space should be sprayed. See the handle and spray it, keep it moist, and cover the light water. 5. Picking coprinus comatus fruiting body is best when it is mature, and it is of good quality and high yield. When harvesting, gently squeeze the base to the left and right and pull it out. Do not bring out the base soil. After harvesting, promptly clean up the noodles, do not leave stray mushrooms, spray once or twice a day to the surface, “keep” the water, keep the soil moist, do not spray too much, until the next batch of mushrooms appeared. Generally can take 4 batches ~ 5 batches of mushrooms. After harvesting Coprinus comatus should be sold or processed in time. Usually two days after harvesting, the umbrella is opened and the value of the product is lost.
