Technological process: select material → pretreatment → sugar stains → sugar boil → baking → packaging. First, raw material selection: choose fresh mushrooms with medium size, natural color, complete mushroom shape and no disease and insect spots as raw materials. Second, pretreatment: 1.

Precocious variety. The optimum growth temperature of mycelium was 24 ℃. The mycelium belonged to creeping or semi-creeping type and was gray-white on wheat grain culture medium. The best temperature for mushroom production was no more than 20 ℃. Under suitable conditions, the material was full in about 14 days, and the mushroom point was seen in 16-18 days after covering soil. The water content of the culture material is about 70%, and the air humidity during mushroom production is 90%, 95%. The first four tidal mushrooms account for about 80% of the total output, turn quickly, and the intertidal interval is 8-11 days. When the material thickness is about 22 cm, the unit yield can be as high as 17 kg / m2.
