To explore the high-yield cultivation techniques and fresh-keeping methods of edible fungi.

After finishing the fresh mushrooms harvested in the cold storage, put them into baskets and baskets, cover the cylinder in the shade with multi-layer wet gauze or hemp bags, hold a small amount of water in the tank, place a wooden frame on the water, put the basket on the wooden frame, and then seal the cylinder mouth with thin film.

After dormancy and fresh-keeping, put it indoors for 3-5 hours above 25 degrees Celsius to make it breathe vigorously, and then put it in a cold storage of about 0 degrees Celsius for about 12 hours, and the shelf life of about 20 degrees Celsius is about 4-5 days.

The method of controlled atmosphere preservation is to manually control the temperature, humidity and gas composition of the environment to achieve the purpose of fresh-keeping.

Simple controlled atmosphere preservation stores fresh mushrooms such as Lentinus edodes and bisporus mushrooms in controlled atmosphere bags with oxygen content of 1%, carbon dioxide 40%, nitrogen 58%, and 49%, which can be stored for about 8 days at 20 degrees Celsius.

"Silicon window" bag fresh-keeping silicone rubber proportionally embedded bag fresh-keeping silicone rubber embedded in the plastic bag wall to form a "silicon window" fresh-keeping bag. The plastic bag can rely on the "silicon window" to automatically adjust the ratio of oxygen to carbon dioxide in the bag. In order to achieve the purpose of safe storage of fresh mushrooms.

Radiation treatment can effectively reduce the deterioration of fresh mushrooms and get a better fresh-keeping effect. Pleurotus ostreatus was irradiated with cobalt 60 rays with a radiation dose of 5-100000 rads and stored at 0 degrees Celsius to keep the color, smell and texture of Pleurotus ostreatus for 7-10 days. Straw mushroom radiation fresh-keeping with cobalt 60 radiation treatment paper-plastic bag straw mushroom, radiation dose of 8-120000 rad, fresh-keeping at 14-16 degrees Celsius for 2-3 days, the commercial character is good.

Chemical fresh-keeping is the use of chemicals to inhibit the respiratory intensity of fungus and prevent the activities of spoilage microorganisms. Soak the fresh mushrooms in 0.6% salt water for about 10 minutes, drain and store them in plastic bags. At 10-25 degrees Celsius, after 4-6 hours, the fresh mushrooms turn bright white and can be kept fresh for 3-5 days. Sodium pyrosulfite spraying 0.15% sodium pyrosulfite aqueous solution to the mushroom body, at 15-20 degrees Celsius, can be stored for 5-8 days. Keep fresh for a long time soak fresh mushrooms in 0.1% aqueous solution of 0.001% Mel for 10 minutes and keep fresh for 5-8 days at 5-22 degrees Celsius.
