Distiller's grains is a very good edible mushroom cultivation raw material, its nutrient composition is suitable for the growth of mycelium of coprinus comatus, not only can reduce the cost of mushroom production, but also can solve the environmental pollution. Distillers grains contain a small amount of ethanol, active Yeast, which is harmful to the growth of mycelium, and has a large acidity and a ph value of 3 to 5. Fresh distiller's grains should be selected and mixed with other raw materials. The formula is: 1 90% of lees, 8% of lime, 1% of gypsum, 1% of ammonium bicarbonate, and biological efficiency of 120% to 130%. 2 Distillers grains 39%, corn cob 39%, rice bran 10%, lime 8%, gypsum 2%, calcium superphosphate 1%, ammonium bicarbonate 1%, biological efficiency 130%. Mixing and selecting seeds will lime, gypsum, ammonium bicarbonate directly into the distiller's grains, adjust the ph value of 9 to 11, other materials (cotton peel, corn cob) is still prepared according to the formulation of mushroom cultivation. The above raw materials are evenly mixed into fermented grains for 5 to 8 hours, spread out after being allowed to cool, and then bagged. Good strains are the prerequisites for high yields, and excellent strains have strong viability, strong ability to decompose the substrate, rapid mycelial growth, wide adaptability, strong resistance, and high rate of mushroom formation. After bagging and seeding, a 50 cm 26 cm polyethylene plastic bag is used and the seeds are sowed in layers, that is, three layers of four layers. Both sides of the bag will spread the strains evenly. The two layers of the strains are closely attached to the outside of the plastic bag. After the bag is filled, 3 to 4 eyes are needled on each strain to facilitate ventilation. According to the temperature determined by the number of bags, the optimal temperature for the germination period is 23°C to 26°C. At this temperature, the mycelium grows quickly and is not suitable for the growth of various bacteria. For the safety of germs, germination temperature is preferably lower, not only hinder the growth of mycelium, but also inhibit the growth of bacteria. Management of fruiting period can be carried out after a period of 30 to 35 days. Yangshuo in the shed should be sterilized and pest-proofed in advance. The soil covered with 2% formaldehyde and 1% dichlorvos mixture must be stuffy and cover the soil for 24 hours. Then 2.5 kg of lime, 2.5 kg of plant ash and 1 kg of phosphate fertilizer should be added every two inches of soil. . The good bacteria of the coprinus colistide bag was removed from the film in the Yangshuo, covered with soil, a thickness of about 4 cm, and then spray a heavy water, and then cover a small arch. During this period, attention should be paid to the adjustment of air humidity and temperature. The suitable temperature for codling season is 13°C～26°C, and the air humidity is about 85%. After about 10 days of growing aerial hyphae on the surface of the soil, it is necessary to ventilate regularly and spray water. When the water is sprayed, it should be sprayed lightly and lightly sprayed. After the emergence of the fruiting body, water can not be sprayed directly. Practice has proved that in the specific management of the watering of the fruiting period, follow the scientific water method of “sprinkling the buds at the mushrooming stage, spraying the space frequently, and seeing the sprinkling of the stipe to keep it moist and cover the light sprayâ€. The picking coprinus cotyledon fruit body is best when it is ripe, good quality and high yield. When harvesting, the base of the mushroom body should be grasped by hand and then gently pulled out. Do not bring out the base soil. After harvesting, clean the noodles in time, do not leave stray mushrooms, spray 1 to 2 times of water every day, keep the soil moist, do not spray too much water, until the next batch of mushrooms appear to stop water. Can generally take 4 to 5 tide mushroom. After harvesting Coprinus comatus should be sold or processed in time, generally two days after harvesting, the umbrella will lose its value.
