Embodiment 1

[0044] According to the medium formula, weigh 74kg of sawdust, 10kg of Juncao, 15kg of bran, 1kg of gypsum powder, 0.1kg of potassium dihydrogen phosphate, 0.05kg of magnesium sulfate, and 60kg of water. Mix the culture material evenly, mix the culture material more than 3 times, and keep the pH value at about 7. Pack the culture material in a plastic bag of edible fungi to a suitable height and tightness, fold the mouth of the bag and squeeze it into the bag. Insert the plastic stick from the mouth of the bag, frame and cover the bacteria bags in order with the mouth of the bacteria bag facing down, and perform high-temperature sterilization on the same day. After the mushroom sticks are cooled to room temperature, use the mushroom liquid strains in the liquid fermenter to inoculate the mushroom sticks with plugs. After the inoculation, immediately plug the mouth of the bag with clean cotton (non-absorbent cotton) to cultivate the bacteria, and after the mycelium culture , Mu...

Abstract

The invention provides a culture medium of a mushroom liquid strain. The culture medium comprises the following main materials: wood chips, bacterial grass, bran, gypsum powder, monopotassium phosphate, magnesium sulfate and water. The invention also provides a method of producing a mushroom bacterium stick by utilizing the mushroom liquid strain. The culture medium provided by the invention has the advantages that the a conventional production method of the mushroom strain is changed, and by the utilization of a liquid-strain technology in the production of the mushroom bacterium stick, not only is the production efficiency improved, but also the production cost is greatly saved; the production method is simple in process, and the utilization rate of the produced strain is high and the pollution rate is low.

Description

technical field [0001] The invention belongs to the field of edible fungus production, and in particular relates to a liquid seed culture medium of shiitake mushrooms and a method for producing shiitake mushroom sticks by utilizing liquid seed technology. Background technique [0002] Shiitake mushrooms, also known as mushrooms and mushrooms, are the fruiting bodies of mushrooms of the family Pleurotus, with high nutritional value. Shiitake mushroom is the second largest edible fungus in the world and one of the special products in my country. It is known as "mountain delicacy" among the people. [0003] The protein content of shiitake mushrooms is as high as 18.6%, the fat content is as low as 4.8%, the carbohydrate content is 71%, and the crude fiber content is 9.6%. Group, iron, potassium, provitamin D (converted into vitamin D after sun exposure). [0004] Lentinus edodes has a variety of biological activities and pharmacological effects. Shiitake mushrooms are sweet ...
