Problems solved by technology

[0004] Some of the current research on the cultivation of Grifola frondosa is mainly aimed at seasonal conventional cultivation, and there are few reports on the high-yield method of industrial cultivation, and there is no report on the research on post-ripening cultivation and the length of the cultivation period.

Embodiment 1

[0012] Embodiment 1: Cultivate Grifola frondosa with the following method (cultivated strains use the "Grifola ash cloud" provided by the Institute of Edible Fungi, Shanghai Academy of Agricultural Sciences)

[0013] 1. Prepare compost: 35% miscellaneous sawdust, 35% cottonseed hulls, 12% bran, 7% corn flour, 10% soil, and 1% gypsum. Mix the compost according to the above ratio, so that the water content is 62%. -65%, PH at 5.5-6.5;

[0014] 2. Bagging: Polypropylene bags are used for bagging with a bagging machine, and each bag contains 900g of wet material;

[0015] 3. Sterilization: Sterilize immediately after bagging, control the temperature at 121°C, and sterilize for 2 hours;

[0016] 4. Inoculation: After the temperature of the material in the bag drops to 20-25°C, inoculate under sterile conditions;

[0017] 5. Bacteria culture: keep the temperature at 23-24°C, relative humidity at 60%-70%, CO 2 The concentration is 1000-2000ppm, with proper ventilation; culture for...

Embodiment 2-5

[0019] Example 2-5 Cultivate Grifola frondosa with the following method (the source of the strain is the same as in Example 1)

[0020] All the other steps are the same as in Example 1, except that post-ripening culture is added after the bacterial culture in step 5, the temperature is 23-24° C., and the relative humidity is 60%-70%, and it is cultivated for 10 days, 20 days, 30 days and 40 days respectively.

[0021] In the following table is the comparison of the grifola frondosa cultivated by the method of embodiment 1-5 on quality and biological efficiency, the result shows: various embodiments, the difference between quality is remarkable, and the best is embodiment 3 and 4 are after ripening for 20 days and 30 days.

Abstract

The invention discloses a grifola frondosa industrial-cultivation method. In a conventional cultivation method comprising the steps of dispensing, bagging, sterilization, cooling, inoculation, spawn runing cultivation, notching bacterium scratching, primordium formation and fruiting body ripening, after the spawn runing cultivation, post-ripening cultivation of 10 to 40 days is added. The cultivation method of the invention has the advantages of reducing days in which primordiums are bred and fruiting bodies are formed in a relatively shorter cultivation period, and improving the quality and biological efficiency.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a factory cultivation method of Grifola frondosa. Background technique [0002] Grifola frondosa (Grifola frondosa). Belonging to the Basidiomycotina Phyllomycetes, Phyllomycetes, Polyporaceae, and Tree Flowers, it is also known as Polypore Bayifolia and Chestnut Mushroom, and it is called "Maitake" in Japan. Its fruit body is tender and refreshing, rich in nutrition and rich in aroma. According to the detection by the Quality Inspection Center of the Ministry of Agriculture and the Institute of Nutrition and Food Hygiene of the Chinese Academy of Preventive Medicine, Grifola frondosa (dry) contains 315.0 g / kg of protein (including 18 kinds of amino acids, the total amount is 186.6g / kg). kg, essential amino acids accounted for 45.5%), fat 17.0 g / kg. Crude fiber 107.0 g / kg, carbohydrate 496.9 g / kg, ash content 6 1.1 g / kg and a variety of beneficial minerals and vitamins...
