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 produces high yields, with an average dry weight of over 20 kilograms per cubic meter of wood, and some high-yield batches can reach 30 kilograms or more—20% higher than traditional methods. The resulting Ganoderma lucidum is firm, glossy, and rich in acid content, with over 90% of the products meeting international export standards.
The cultivation season plays a crucial role in the success of this process. Ganoderma lucidum thrives in medium to high temperatures, and its yield depends on the type of wood, timing, and cultivation techniques. Inoculation can be done between late October and December, or from early February to early March. Depending on the timing, growers can expect 2–3 harvests. If inoculated before mid-December, the main harvest occurs in March of the following year, accounting for over 70% of the total yield. If planted in early February, the output reaches about 55% by April.
For raw materials, broad-leaved hardwood trees are ideal, especially those with hard leaves, such as rice bran or eucalyptus. Using softer wood types can significantly reduce the second-year yield. Trees with diameters ranging from 8 to 20 cm are best, and cutting should be done 3–5 weeks before inoculation. The wood should be prepared one week prior, ensuring the moisture content stays between 38% and 45%.
The cultivation material typically consists of wood chips mixed with additives like wheat bran and gypsum. Plastic bags made of low-density polyethylene (0.45–0.6 mm thick) are used, with mouth diameters of 14, 15, or 20 cm and lengths of 45–55 cm.
The production process involves several key steps: logging and cutting the wood, bagging, sealing, sterilization, inoculation, mycelium growth, bed preparation, management, and harvesting. After sterilizing the logs at atmospheric pressure for 12–14 hours, they are inoculated in a clean room using aseptic techniques. Each cubic meter of wood usually requires 90–130 bottles of culture, which helps speed up colonization and reduce contamination.
Once the mycelium fully colonizes the wood, it is transferred to outdoor beds. A well-ventilated, sunny shed with good drainage is chosen. Before placing the wood, the area is cleared of weeds and pests, then disinfected. The wood is buried in a 100–120 cm wide, 20 cm deep trench, with a walkway left for access. The temperature should be kept between 16°C and 22°C during this stage.
After planting, the surface must remain moist, and the shed temperature should stay between 26°C and 30°C. Buds usually emerge within 15–20 days, and maintaining humidity at 85–90% is essential. Proper ventilation, temperature control, and light exposure help the caps develop properly. Once the cap color darkens and spores begin to release, the harvesting period begins. At this point, watering is stopped to ensure optimal quality before collection.
