Detailed Explanation of Ganoderma lucidum Field Hole Cultivation Technology

Ganoderma lucidum is a traditional medicinal fungus in China, and it was praised as the "fairy grass" by people long ago. In recent years, with further development and research on Ganoderma lucidum, and in the increasingly developed modern society, people's desire for longevity has become stronger and stronger; therefore, its market prospects are promising. Field cultivation of Ganoderma lucidum is a model that uses vacant rice fields to grow Ganoderma lucidum. Practice has shown that, calculated at 120,000 bags planted per hectare, the profit in half a year can reach ten thousand yuan. In today's effort to adjust the structure of agricultural industrialization and cultivate new rural economic growth points, it is undoubtedly another effective new way. The specific cultivation methods are introduced as above.

1 Stick Making and Spawn Running

1.1 There are 3 formulations for the culture material, and any one may be selected. First, cottonseed hulls 44%, miscellaneous wood sawdust 30%, wheat bran 20%, corn flour 3%, gypsum powder 1%, sugar 1%, superphosphate 1%, water about 65%, natural pH; second, miscellaneous wood sawdust 72%, wheat bran 20%, corn flour 5%, superphosphate 1%, sugar 1%, gypsum powder 1%, water about 65%, natural pH; third, cottonseed hulls 78%, corn flour 2%, wheat bran 15%, gypsum powder 1%, superphosphate 1%, sugar 1%, water about 65%, pH about.

1.2 Bagging and Sterilization According to local actual conditions, choose any one of the above formulations and mix the material well. The plastic bags used for making mushroom sticks generally use low-pressure polyethylene, specifications 60 cm x 15 cm, thickness 4-5 mm, and each bag holds about 1 kg of dry material. When bagging, first tie one end of the tubular material tightly with a plastic rope, then fill the material. The material must be packed firmly; when filling by hand, press the material with a wooden stick while filling. For large-scale cultivation, it is best to use a bagging machine, which is both fast and good. When the culture material is filled to 8-12 cm from the bag opening, tie the bag opening tightly with a dead knot in the same way. Bag on the same day, sterilize on the same day. Sterilization generally uses normal pressure, that is, after the temperature in the sterilization stove rises to 100°C, maintain it for 10-12 hours.

1.3 Inoculation and Spawn Running After the bag temperature drops to 30°C, inoculate aseptically in an inoculation box or inoculation room. Inoculation method: use a sterilized hole puncher like a hollow drill bit to punch 4 holes on the bag surface, arranged at equal distances in a straight line, with a hole diameter of about 1.5 cm, then use tweezers to pick up 1 small piece of spawn and quickly insert it into the hole, and stick about 12 square cm of adhesive tape over the hole opening. The inoculated mushroom sticks are immediately placed in the culture room for cultivation. The culture room must be clean and sanitary, and must be fumigated and disinfected with formaldehyde or sulfur in advance; during cultivation, the temperature requirement is 22-25°C. After one week of cultivation, turn the mushroom sticks once from top to bottom and from inside to outside. When turning, arrange the mushroom sticks in a well-shaped pattern, with 8-12 layers per row and 3 bags per layer. Starting from the first turning, turn again every 5-6 days in the same way. This allows the mushroom sticks to be ventilated and breathable and also convenient for inspection. When the mycelium at the inoculation holes grows beyond the adhesive tape, uncover one corner of the adhesive tape to increase oxygen. After the mushroom sticks are cultivated for 45-60 days, the mycelium will form clumps, and at this time they can produce mushrooms.
