Main cultivated varieties of Mushroom in China

1. The mushroom of mushroom strain 27962796 is round, scaleless, semimembranous, thick in cap and short in stalk. The tissue is strong, the bacterial fold is compact, the color is light, and there is no shedding phenomenon. It contains 90 grains of mushroom per kilogram, the water content of fresh mushroom is high, and the pre-cooking rate is 65%. The strain is suitable for secondary fermentation. The growth rate of mycelium is moderate and fast. More resistant to fertilizer, resistance and high temperature. The mushroom emergence period is 3-5 days later than that of common mushroom strains. The mycelium has strong soil climbing ability, strong kink force and high mushroom rate. Mushrooms are basically solitary. The mushroom will not die at about 20 ℃. The yield structure of Pleurotus ostreatus is uniform and the stamina is strong, so it can be cultivated in advance. Generally, the average unit yield is about 9 kg per square meter, and the highest output can reach 15 kg per square meter. 2. The mycelium of Zhenong No. 1 is a semi-creeping strain, which has the advantages of rapid growth, strong mycelium vitality, water resistance, fertilizer resistance, disease resistance, wide adaptability and high temperature tolerance. Zhenong No. 1 strain developed slowly on the test tube medium, and the hyphae showed fine lines of villi. The mycelial growth rate of original and cultivated species is fast. Sowing on the mushroom bed culture material to eat the bacteria quickly, there are many soil-penetrating hyphae and vertical hyphae in the soil layer, the mushroom type is medium and large, and the color is white. In the case of dry climate and lack of water and fertilizer, the cover is easy to appear flat and scale. The first-generation hybrid of 3.As1671As1671 strain 176and 8211 was obtained by pairing hybridization, and then the second-generation hybrid was obtained by single spore isolation. The fruiting body of the strain is round in shape, white in color, aseptic ring and scale, thick and short mushroom stalk, strong tissue, light pleated color, medium mushroom type, with an average of 110 per kilogram, and the finished product rate is high. The strain is not resistant to high temperature and high concentration of carbon dioxide, otherwise Pleurotus ostreatus will not appear. When there is a lack of fertilizer and water, small white spots are easy to appear in the center of the stalk. The unit yield is 6-9 kilograms per square meter. 4. The mycelium of Min 1 was thick white on the test tube culture medium, and the aerial hyphae were developed, white, neat, sturdy, short and dense, and the growth rate was slightly slower. On the dung grass culture material, the strain germinates fast, the growth is strong, the anti-pollution ability is strong, and the survival rate of the strain is high, but it requires high planting technology. The hyphae are easy to form integument. Dead mushrooms will appear above 21 ℃, and the fruiting body is sensitive to temperature. When the temperature difference is large and the temperature changes sharply, it is easy to open umbrellas and dead mushrooms, especially in the third tide. On the mushroom bed, the mushroom setting ability is strong, the mushroom is dense, the tide turns quickly, the tide is obvious, the yield is stable and high, with an average of 80 kilograms per kilogram, and the highest yield is 14 kilograms per square meter. The fruiting body is round, the mushroom color is white, the mushroom cover is thick and without scales. The bacterial fold is small and light, and the stalk is thick and short, so it is not easy to open the umbrella. The mushroom type is medium to large. The first-grade mushroom accounts for 60%-70%, which is an excellent canned variety. 5.As1789 strain As1789 is an aerial strain, which has fast germination and strong growth potential. The hyphae on the bed had a strong ability to climb the soil, and no overgrowth was found. This variety produces mushrooms slightly slowly, but the mushrooms are neat and uniform. The mushroom body is round, the color is white, the aseptic ring mark, the tissue is strong. The cover is not easy to open the umbrella, the yield is high, the blossom shape is medium, 100 per kilogram. 6.As376As376 strain has strong mushroom-setting ability, great potential to increase yield and short time to turn tide. However, the tide is not obvious and the production is relatively stable. The average grain weight is 100 grains per kilogram. The mushroom shape is round, the handle is thick, the cover is medium, the top is slightly flat, it is not easy to open the umbrella, the color is white, there is no scale, aseptic ring, the color of the fold is light, and the tissue is strong. The pre-cooking period can reach 70% to 72%.
