The technique of cultivating Coprinus comatus with Distiller's grains

Distiller's grains is a kind of good material for edible fungi cultivation. Its nutrient components are suitable for the growth of mycelium such as coprinus comatus, etc., which can not only reduce the production cost of edible fungi, but also solve environmental pollution. Distiller's grains contain a small amount of alcohol harmful to mycelium growth, active yeast, high acidity, pH value about 3-5 between. Fresh distiller's grains are selected and matched with other substances, and the formula has the following types: Formula 1: 90% distiller's grains, 8% lime, 1% gypsum, 1% ammonium bicarbonate, the biological efficiency is 120-130%; formula 2: 39% distiller's grains, 39% corn cob, 10% rice bran, 8% lime, 2% gypsum, 1% calcium superphosphate, 1% ammonium bicarbonate, the biological efficiency is 130%; formula 3: 50% distiller's grains, 30% cotton husk, 8% bran, 8% lime, 2% gypsum, 1% calcium superphosphate, 1% ammonium bicarbonate, the biological efficiency is 130%. 1. Mix the ingredients. Lime, gypsum and ammonium bicarbonate are directly mixed into distiller's grains, pH value is adjusted to 9-11, other materials (cotton husk and corncob) are still prepared according to the formula of Pleurotus ostreatus and Coprinus comatus, then evenly mixed into distiller's grains for fermentation for 5-8 hours, spread out and cooled, and packaged. The mixture must be uniform, and the pH value must be increased to 9-11 in the early stage. 2. Select high-quality and high-yield strains and use high-quality cultivated seeds. Excellent strains are the first condition for high yield, and the prerequisite for high yield. Moreover, excellent strains have strong vitality, strong decomposition ability to substrate, fast mycelium growth speed, wide adaptability, strong resistance and high mushroom rate. 3. bagging and sowing. After mixing the materials, 50×26 polyethylene bags are selected, and the layered seeding method is adopted, that is, three layers of materials and four layers of seeds are planted, the two ends of the bag are evenly placed, the middle two layers of seeds are closely attached to the outer side of the plastic bag, and 3-4 eyes are tied on each seed block with a hand needle after filling the bag, so as to facilitate ventilation. According to the temperature to determine the number of layers of the code bag, the most suitable temperature for the bacteria period is 23-26℃, this temperature is the fastest growth of hyphae, and is not suitable for the growth of miscellaneous bacteria, in order to safely develop bacteria, the temperature of the bacteria is best to be lower, which does not hinder the growth of hyphae, but also inhibits the growth of miscellaneous bacteria. 4. fruiting period management. After 30-35 days of growth period, fruiting period management can be carried out. The sunny beds in the shed should be sterilized and insect-proof in advance, and the soil covered with 2% formaldehyde and 1% dichlorvos mixed solution should be piled for 24 hours in advance. removing the film from the mushroom bag and lying horizontally in a sunny bed, covering the bag with soil, the thickness of which is about 4 cm, spraying heavy water once, covering a layer of small arch shed, and paying attention to the adjustment of space humidity and temperature during this period. The suitable temperature for the mushroom growing period is 13-26 DEG C, and the space humidity is about 85%. After about 10 days of soil surface growth, regular ventilation is required, and water spraying is carried out at the same time. The principle of water spraying is to spray less and lightly. After the fruiting body appears, it is not allowed to spray water directly. At this time, it is necessary to increase the humidity of the space and strengthen ventilation. Before ventilation, the mushroom room should spray water first. The practice proves that in the concrete management of spraying water in fruiting stage, it is necessary to follow the scientific water use method of prohibiting spraying in budding stage, spraying frequently in space, spraying according to fruiting stalk, keeping wet and spraying lightly in cover. 5. Harvest. Coprinus comatus fruiting body picked best when seven mature, and good quality, high yield. When harvesting, pinch the base with your hands and turn it left and right, gently pull it out, do not bring out the soil at the base. After harvest, clean the ridge surface in time, do not leave residual mushrooms, spray "keep" water 1-2 times a day to the ridge surface, keep the soil layer moist, do not spray too much until the next batch of mushrooms appear. Generally, 4-5 batches of mushrooms can be collected. Coprinus mushroom after harvest should be sold or processed in time, generally two days after harvest that is open umbrella, lose commodity value.
