Technical points of corncob cultivation of Ganoderma lucidum
Ganoderma lucidum, also known as red ganoderma lucidum, is a traditional precious medicinal material. The average retail price of the market is 150-200 yuan. For a long time, artificial cultivation has used wood or sawdust as the main material, combined with auxiliary materials for large-scale production, while corn cob cultivation of Ganoderma lucidum has rarely been reported. When developing edible (medicine) fungus production, the author carried out experiments on cultivating Ganoderma lucidum with corncob, and achieved good results. The technical points are described as follows:
1. Raw material handling. Choose fresh, dry, mildew-free corncob, crushed into soybean grain size, placed in a ventilated place for later use.
2. Culture medium formula. Because corncob nutrition is relatively simple, nitrogen content is low, affect mycelium growth. Therefore, nitrogen source should be supplemented when preparing culture medium. The reasonable formula is: corncob 74%, bran 25%, gypsum 0.5%, plant ash 0.5%.
3. Bagging sterilization. Generally, pressure polyethylene bags of 15cm-45cm-0.04 mm are used. Before bagging, corncob culture material should be pre-wetted 10-12 hours in advance, and the water content should be controlled at 65%, then bagged and sterilized in time. sterilize under normal pressure, maintain for 12 hours when that temperature in the pot reaches i00-C, then stop heating, naturally cool, and then take out.
4. Inoculate culture. Inoculation room must be clean, dry house, can be surrounded by plastic film into 2m×2m×2m small chamber, and then inoculate inside, adopt two combined hole inoculation method. After inoculation, the material bag is moved into a culture room to cultivate bacteria, the temperature is maintained at about 25 DEG C, the bacteria are cultivated under dark conditions, and after 40-45 days, the hyphae enter physiological maturity and are ready to be produced.
5. Management of the plant. When the temperature is above 22℃, light should be increased to loosen the bag mouth and strengthen ventilation to promote the formation of fruiting body. After fruiting body formation, air humidity increases to 90%-95%. It takes about 25 days from bud formation to harvest. The criterion for fruit body ripening is that the color of the edge is the same as that of the middle. After maturity, it should be further cultured for 7-10 days to make the fruiting body thicker.

Cultivate Ganoderma lucidum and become rich.
Xie Guoling, Bai Si Village, Bai Si Town, Shangshui County, became rich by artificially cultivated Ganoderma lucidum, making a profit of 100000 yuan a year. Xie Guolan has been engaged in individual transportation for a long time since he was demobilized from the army in 1982. In 2001, his son, who studied edible fungi in a bioengineering company, taught him the techniques of cultivating Ganoderma lucidum. In January last year, he rented 4 mu of vacant land and 17 houses, and built a production shed. After scientific preparation, preparation, inoculation and management, 2000 bacterial bags were cultivated successfully. The success of the trial has strengthened Xie's confidence, and he continues to expand.
