Formulation of culture medium: Poplar mushrooms can grow at a nitrogen and carbon content of 301 to 941. Cottonseed, broad-leaved wood chips, and corn cobs can all be cultivated. However, blends are preferred. The following recipes can be selected based on local resource conditions: 1, 78% of cottonseed skin, 18% of wheat bran; 2, 78% of sawdust and 18% of wheat bran; 3) 25% of cottonseed hull, 35% of sawdust, 16% of corn cob, and 20% of bran. The above formula is added with 1% of sugar, lime, gypsum and trace elements, and the ratio of material to water is 11:35.
Sterilization and inoculation of bacteria: 1. Cultivation bags are made of low-pressure, high-density polyethylene bags of 17 cm, 34 cm, and 0.05 cm in size. The amount of the bags is 3/4 of the whole bag, and the remaining 1/4 is used as a tie. 2, atmospheric pressure sterilization at 100 °C, keep more than 8 hours, stuffy overnight pan, bacteria bags should be lightly put, do not break the bag, and cooling. 3. When cooling to 25°C, inoculate in the bacteria seed box or sterilization room under aseptic conditions. The inoculation volume is appropriate to cover the mouth of the bag, and the leather bag is used to fold and tie. 4, inoculated with a good bag, into the mushroom shed laying, culture bag germination temperature below 25 °C, when the mycelium into the material within 3 cm long, you can release the zipper holster, oxygen, so conducive to hair bacteria. At the same time to avoid direct sunlight bag, bacteria found in a timely manner.
Mushroom management and harvesting: After 30 days of incubation at 25 °C, mycelium can be covered with bacteria bags. 1. When the material surface meets the small primordium, it enters the mushrooming stage. At this time, the bag mouth should be unlocked, and the bag can be placed upright on the surface of the shed. 80 bags can be placed on 1 square meter to start giving light stimulation and spraying water. Increase the humidity in the greenhouse, protect the small buds and prevent the wind from blowing the mushrooms. 2. When the mushroom buds form the cap of the mushroom, straighten the mouth of the bag and cover it with a layer of newspaper. Spray the water on the newspapers sooner or later. This will allow the stipe to elongate, control the lid of the mushroom, and open up more products. mushroom. 3, when the cap diameter to 3 cm long, stipe length to 8 cm or so, and when the mushroom cover is not open when the umbrella harvest, but also can adopt large and small. In order to achieve product specifications, it is common to leave 20 or so mushrooms in each bag. In order to increase the output, after harvesting a mushroom, the film is peeled off and the soil is covered with soil. If properly managed, the conversion rate can reach 100%.
Collagen is the most abundant protein in mammals, accounting for 25% to 30% of the total protein. It is widely present in all tissues from the body surface of lower vertebrates to mammalian bodies. Collagen monomers are long cylindrical proteins with a length of about 280 nm and a diameter of 1.4–1.5 nm. It consists of 3 polypeptide chains that are supercoiled around each other.
