Quick freezing and Refrigeration of Edible Fungi
Quick-frozen storage of Lentinus edodes: the production of Lentinus edodes has developed vigorously in the north and south of China in recent years. Since the popularity of bag-planted Lentinus edodes in Fujian, Zhejiang, Henan, Hubei and other provinces have successfully developed bag-planted Lentinus edodes. Quick-frozen storage of Lentinus edodes has become an indispensable and important fresh-keeping technology in production and sales. The quick-frozen storage of Lentinus edodes is more simple and convenient than that of mushrooms. Generally, fresh mushrooms are pre-cooled in ice water, removed and drained, quickly frozen in an ultra-low humidity freezer of 60 ℃, and then stored in a 24 ℃ freezer of-18 ℃.

Identification of Edible Fungi
Identification of edible fungi the mycelium of Pleurotus ostreatus is white, dense, stout, cotton-wool-like, and those with wall-climbing phenomenon are excellent strains. If the bacteria cultured with sawdust, the decomposed sawdust is light yellow, and a small amount of primordia appear, which is an excellent strain. If the mycelium is sparse or bundled, the cotton shell culture medium is dark red, the sawdust culture medium is white, the hyphae breaks away from the bottle wall and shrinks, there is yellow liquid accumulation at the base of the bottle, or mildew spots appear on the surface of the culture material, it is inferior bacteria. The mycelium of Auricularia auricula is white and neat, and it is an excellent strain. If

Preservation of Mother species of Edible Fungi
The mycelium of edible fungi propagates quickly and is easy to mutate, so it is difficult to preserve the strains. This paper introduces four effective and simple methods. 1. Liquid paraffin preservation method: after high-pressure sterilization of liquid paraffin, put it in a thermostat for several hours or in a dryer for several days, absorb liquid paraffin with a sterile straw or syringe and inject it into the strain test tube. The injection amount should be about 1 cm higher than the tip of the inclined plane. Plug with cotton stopper, seal with wax, store upright in low temperature, can be preserved for 5 years. 2. weigh a certain amount of wheat bran by preservation method, add water or nutrient solution and mix well.

Appearance Identification of Mother species of Edible Fungi
Excellent and purified strains are the fundamental guarantee for the successful cultivation of edible fungi. Several methods for identifying the mother species of edible fungi are introduced as follows: the mycelium of Lentinus edodes on potato glucose Agar (PDA) medium is pure white, stout, flocculent or fluffy, has a certain wall-climbing ability after full test tube, and the edge is irregular and wavy. At the temperature of about 24 ℃, the mycelium can cover the inclined surface of the test tube in 15 days. With the special fragrance of Lentinus edodes. The hyphae of Pleurotus ostreatus were white, dense and stout on PDA medium.

A simple method for making Mother species of Edible Fungi
PDA or PSA and their improved culture medium are mostly used in the production of edible mushroom mother seed, but in some remote areas or small batch production, the raw materials in the formula are difficult to be purchased in rural areas due to the high price (generally analytical purity) and delay production. This paper introduces several simple production methods. 1. Gelatin medium. Gelatin, which refers to edible gelatin, is sold in general food and chemical stores at a lower price. Gelatin used as a coagulant or solidifying agent in food production, instead of Agar (watercress, Agar) as coagulant in mother seed production.

Preparation of Mother Culture medium for Edible Fungi
1. 800 grams of corn, 20 grams of glucose, 20 grams of Agar, 1.5 liters of rice water. First, boil the corn kernels in dilute Amoy rice water, pick them up when a small amount of corn kernels burst and filter. Continue to heat the filtrate (if the filtrate is less than 1 liter, add clean water to make up), add Agar and glucose, stir until all the Agar dissolves, then separate the test tube, sterilize and place the bevel. two。 Fresh Pleurotus ostreatus or mushroom foot 200 grams, glucose 20 grams, Agar 20 grams, water 1 liter. The preparation method is the same as potato glucose Agar medium. 3. Wheat bran 2

Key techniques of early Operation of Edible Fungi Culture material
It is very important to make a good culture material of edible fungus, which directly affects the growth of edible fungus and the benefit of growers. Here I will take Gymboree starter as an example to introduce the essentials of operation. 1. Preparation: according to 0.1% of the weight of the culture material (that is, 1/1000, if the newspaper waste is reused, 0.2% can be added) to prepare Gymboree edible mushroom culture material fermentation auxiliaries; pre-soak or pre-wet the crushed or cut-off main materials, adjust the moisture to 60%, 70%, and the PH value is about 8. The moisture content is too low, which is not conducive to the rapid propagation of functional microorganisms.

Smart picking of edible fungi
Edible fungi are vegetables rich in nutrients and popular with urban and rural people. They are also an important way for farmers to increase their income. Therefore, in the process of picking, we should master the following techniques: First, master the best harvest period. All kinds of mushroom ears basically have beautiful appearance, fresh complexion and delicious taste when they mature in July and August. Take shiitake mushroom as an example, the mature sign in July and August; the bacterial membrane has been broken, the cap has not been fully developed, there are still a few inward rolls, forming a "gong edge", the pleats have all elongated, from white to white

Skillful use of secondary bagging to avoid infection of edible fungi
In the production practice of Lentinus edodes, hericium Erinaceus, Auricularia auricula, etc., the secondary bagging technology (that is, adding a film bag when the mushroom tube comes out of the stove, so that the mushroom tube does not directly contact the ambient air) is used for production, which effectively solves the problem of cross-infection in the production process of the mushroom tube, and keeps the survival rate of the strain above 97%. The technology is introduced as follows: 1. For the preparation of the outer bag, it is appropriate to choose a low-pressure polyethylene film bag with a perimeter greater than the perimeter of the inner bag, a length of 5 cm longer than the inner bag and a thickness of O.2 silk.

Control method of edible fungi Penicillium
Penicillium is also called Chloromycetes. Common Penicillium species in edible fungi production include Penicillium frequentans, Penicillium lilacinum, Penicillium viridicum, Penicillium chrysogenum and Penicillium verruculosum. Penicillium can infect and harm many kinds of edible fungi such as Pleurotus ostreatus, Mushroom and Lentinus edodes during seed production and cultivation. (1) Hazard
