Distillers' grains suitable for cultivation of Coprinus comatus
Distiller's grains is a good edible mushroom cultivation material, and its nutrient composition is suitable for the growth of coprinus comatus mycelia, which can not only reduce the production cost of coprinus comatus, but also prevent environmental pollution. Distillers grains contain a small amount of ethanol, active yeast, which is harmful to the growth of mycelia, and has a large acidity and a pH of 3 to 5. Therefore, fresh distiller's grains should be chosen and mixed with other raw materials. Formula: Distillers grains 90%, Lime 8%, Gypsum 1%, Ammonium bicarbonate 1%; Distillers grains 39%, Corn heart 39%, Rice bran 10%, Lime 8%, Gypsum 2%, Superphosphate 1%, Ammonium bicarbonate 1%.
When mixing spices, lime, gypsum and ammonium bicarbonate are directly mixed in the distiller's grains, and the pH is adjusted to 9-11. The other ingredients (rice bran and corn heart) are still prepared according to the formula for cultivating oyster mushroom and coprinus comatus. 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. After adjustment of good material, use a 50cm 26cm polyethylene plastic bag, using stratified sowing method, that is, four layers of three layers of material, the bacteria on the two sides of the bag evenly swing open, the middle two layers of bacteria close to the plastic On the outside of the bag, use 3 to 4 needles on each of the bacterial seed blocks after filling the bag to facilitate ventilation. According to the temperature, it determines the number of layers of the bag. For the safety of germs, germination temperature is preferably lower, not only hinder the growth of mycelium, but also inhibit the growth of bacteria. After 30 to 35 days of germination, it is time to enter fruiting period management.
