How to cultivate ganoderma lucidum in short section wood clinker
Short-stemmed wood clinker cultivation is an innovative technique for growing *Ganoderma lucidum* that has gained significant popularity in recent years. This method yields impressive results, with an average dry weight of over 20 kg per cubic meter of wood. In some cases, the yield can exceed 30 kg, which represents a 20% improvement compared to traditional methods. The resulting *Ganoderma lucidum* is firm and glossy, with a high acid content in the bag material. More than 90% of the produced mushrooms meet international export standards.
**Cultivation Season**
*Ganoderma lucidum* is a medium-to-high temperature fungus, and its growth is influenced by the species, timing, and techniques used. Inoculation can be scheduled from late October to December or from early February to early March. Under favorable conditions, the mushroom can produce 2-3 batches of fruit bodies. If inoculated before mid-December, the first harvest occurs in March of the following year, contributing more than 70% of the total annual yield. If inoculated in early February, the harvest in April accounts for around 55% of the total output.
**Raw Materials**
Broad-leaved hardwoods are ideal for cultivating *Ganoderma lucidum*, with hard-leaf varieties typically producing higher yields and better quality. Species such as rice bran, eucalyptus, and others are commonly used. However, if looser materials are used, the second-year yield may drop significantly. Logs with diameters ranging from 8 to 20 cm are preferred. Cutting should occur 3–5 weeks before inoculation, with final trimming done about a week prior. The moisture content should be maintained between 38% and 45%.
The main raw material is mixed wood chips, supplemented with small amounts of wheat bran and gypsum powder. Plastic bags made from low-density polyethylene, with a thickness of 0.45–0.6 mm, are used. These bags have mouth diameters of 14, 15, or 20 cm and are 45–55 cm long.
**Production Process**
The process includes several key steps: preparation of logs, bagging, sealing, sterilization, inoculation, mycelium cultivation, bed preparation, management, and harvesting.
1. **Bagging**: Logs are cut into 30-cm sections, placed in bags with wooden bases, and covered with swarf materials. They are then sterilized at atmospheric pressure for 12–14 hours at 100°C.
2. **Inoculation**: After sterilization, the logs are moved to a clean room for aseptic inoculation. Each cubic meter of wood typically uses 90–130 bottles of spawn. Proper inoculation helps speed up mycelium colonization and reduces contamination risk.
3. **Mycelium Culture**: The bags are placed in a disinfected room, stacked in a "well" shape, and kept at 20–25°C. Daily ventilation is introduced after one week, gradually increasing as the mycelium develops. After 60–70 days, the mycelium is mature, and the logs are ready to be buried in soil.
4. **Bed Preparation**: A sunny, well-ventilated shed is chosen. Before placing the logs, weeds and pests are removed. The ground is prepared with trenches 100–120 cm wide and 20 cm deep, with walkways left for access. The area is disinfected, and ant control measures are taken. The logs are then buried at temperatures between 16°C and 22°C.
5. **Zhi Zhi Management**: After burial, the surface is kept moist, and the shed temperature is maintained between 26°C and 30°C. Buds typically emerge within 15–20 days. Relative humidity must stay between 85% and 90%. Proper ventilation, temperature, and humidity control are crucial for cap development.
6. **Harvesting**: The mushrooms are ready for harvest when the yellow-white growth ring on the edge of the cap disappears, the cap color deepens, and it begins to thicken. At this stage, spores start to release, and watering should be stopped before picking.
