Background
Fresh sea mushroom brand nameHypsizygus marmoreus (Peck) H.E.Bigelow]Hypsizygus marmoreus, which is crispy and tender in texture, fresh in taste, and has sea crab flavor, is called "Hypsizygus marmoreus" or "Hypsizygus marmoreus" in Japan. Belonging to the family Tricholomataceae and genus Hypsizygus, and having medium to large fruiting body. Nowadays, two strains of light grey and pure white are cultivated, and white strains also called white beech mushroom and yulong mushroom are mostly cultivated in factories. The diameter of the pileus is 3-15 cm. Growing broad-leaved trees on dead wood and inverted rotten wood in late summer to autumn, and growing in clusters. Is an excellent edible fungus in the northern temperate zone. Is a low-calorie and low-fat health food.
The seafood mushroom belongs to low-temperature type grassy fungi or woody white rot fungi, has high nutritional value and medicinal value, white color, fleshy and thick fungus flesh, and has delicate taste, fragrant smell and delicious taste. The protein of the hypsizygus marmoreus contains various amino acids, including 8 amino acids necessary for human body, and also contains various polysaccharides, and the hot water and organic solvent extract of the fruiting body of the hypsizygus marmoreus has the function of eliminating free radicals of human body, so that the hypsizygus marmoreus has the effects of resisting cancer, preventing cancer, improving immunity, preventing aging and prolonging life when eating the hypsizygus marmoreus frequently. The edible fungus has high nutritive value and medicinal value, white color, rich meat, delicate taste, fragrant smell and delicious taste. The optimal temperature for hypha growth is 24-26 deg.C, and the optimal temperature for fruiting body growth is 8-18 deg.C. Cultivation in autumn and winter, the fungus age is about 50 days, the growth cycle is 100 days, and the biotransformation rate is 60-80%. The price of the fresh food sold in the market is 20-30 yuan per kilogram.
In order to meet the market demand, people invent a fungus bag cultivation method capable of improving the yield of the seafood mushrooms, and the method comprises the steps of filling a culture medium into a cultivation bag to obtain a culture medium rod, sterilizing the culture medium rod, and then inoculating strains into the culture medium rod. In order to promote hypha to grow over the fungus bag as soon as possible, people start to adopt a puncher made of wood and iron rods, and an inoculation hole shaper made of plastic and provided with a cylinder at the upper middle part and a cone at the lower part temporarily punches holes in the fungus bag during inoculation, so that the strains are inoculated into the hollow holes. The pollution probability is high after the perforation and the strain inoculation; the gap between the strains and the culture medium of the fungus bag is large, the fruiting is irregular, and the inoculation efficiency is low.
