Fixed Point cultivation techniques of Ganoderma lucidum in Field

Ganoderma lucidum is a traditional medicinal fungus in China, which was known as "fairy grass" a long time ago. In recent years, with the further development and research of Ganoderma lucidum, and in the increasingly developed modern society, people's desire to prolong life is getting stronger and stronger, so its market prospect is promising. The cultivation of Ganoderma lucidum in the field is a model of growing Ganoderma lucidum in empty parent rice fields. Practice has proved that if the planting of 120000 bags per hectare is calculated, the profit can reach 10,000 yuan in half a year. It is undoubtedly a new and effective way to adjust the structure of agricultural industrialization and cultivate new economic growth points in rural areas. Now the specific cultivation methods are introduced as above.

1.1 there are three kinds of culture material formulations that can be selected at will. One is cottonseed husk 44%, miscellaneous sawdust 30%, wheat bran 20%, corn meal 3%, gypsum powder 1%, sugar 1%, calcium superphosphate 1%, water 65%, PH value natural; second, miscellaneous sawdust 72%, wheat bran 20%, corn meal 5%, calcium superphosphate 1%, sugar 1%, gypsum powder 1%, water 65%, PH value is natural. Third, cotton husk 78%, corn meal 2%, wheat bran 15%, gypsum powder 1%, calcium superphosphate 1%, sugar 1%, water about 65%, PH value about.

1.2 bagged sterilization according to the local actual situation, choose one of the above ingredients. Plastic bags for making bacterial rods are generally made of low-pressure polyethylene, with specifications of 60 cm × 15 cm and thickness of 4-5 mm. Each bag contains about 1 kg of dry material. When bagging, first tie one end of the cylinder with a plastic rope and tie it tightly, then load the material, the material must be loaded, and press the material with a wooden stick while loading it by hand. Large area cultivation is best bagged with a bagging machine, which is fast and good. When the culture material is loaded to the bag mouth 8-12 cm, the bag mouth is also killed and ligated tightly. Bagging on the same day and sterilization on the same day. Atmospheric pressure is generally used for sterilization, that is, the temperature in the sterilization stove is kept for 10-12 hours after rising to 100 ℃.

1.3 inoculate bacteria after the bag temperature drops to 30 ℃, inoculate in the inoculation box or inoculation room according to aseptic operation. Inoculation method: use a sterilized hole punch like a hollow bit to punch four holes on the surface of the bag, arrange them in a straight line at an equal distance, with a pore diameter of about 1.5 cm, and then quickly insert a small piece of bacteria into the hole with tweezers. Apply 12 square centimeters of adhesive tape to the mouth of the hole. The inoculated rods were immediately put into the culture room for culture. The culture room should be clean and sanitary, and should be fumigated with formaldehyde or sulfur in advance, and the temperature should be 22-25 ℃. After a week of culture, the stick was turned up and down once inside and outside. When it was turned, the stick was arranged in a well shape with 8-12 layers per row and 3 bags per layer. After turning the pile for the first time, turn it again every 5-6 days, the method is the same as above, this can make the bacteria stick not only ventilated and breathable, but also easy to check. When the mycelium of the inoculation point grows beyond the adhesive tape, a corner of the adhesive tape should be opened to increase oxygen. When the bacteria stick is cultured for 45-60 days, the hyphae will agglomerate, and the mushrooms can be produced at this time.
