What are the inoculation methods for shiitake mushrooms? A detailed explanation of common inoculation techniques
Shiitake mushroom (Lentinula edodes) is the world's second-largest edible fungus and one of China's unique edible fungi. It has a delicious flavor and is rich in nutrients, and it is cultivated in every region of China. When cultivating shiitake mushrooms, the first thing to do is mycelium inoculation, so how should shiitake mushrooms be inoculated? Let's take a look.
1. Dense inoculation method
This method is mainly intended to increase the inoculation points on the log. The more inoculation points there are, the larger the colonization area, and the mycelium can penetrate the log in a shorter time. The log exchanges gases with the outside mainly through the absorption and evaporation of water. The alternating movement of dry and wet conditions allows the interior of the log to get sufficient requirements, enabling the mycelium to penetrate deep into the log, obtain more nutrients, accelerate the maturation of the log, and reduce infection of the mycelium by contaminating fungi.
2. Deep inoculation method
The inoculation holes should be dug deep, which not only holds more spawn but also helps prevent drought. It can reduce the external temperature difference affecting the spawn blocks at the bottom of the inoculation holes, which is favorable for mycelial growth. The mycelium of the spawn blocks will germinate quickly under stable temperature and humidity conditions, so the survival rate is relatively high. Digging deep holes can also increase the depth in the tangential direction of the wood, allowing the mycelium to absorb more nutrients. This point is similar to the dense inoculation method, but it artificially controls the inward growth of the mycelium, clearly improving yield.
3. Early inoculation method
When shiitake mushroom spawn is inoculated in a low-temperature environment, the density of contaminating fungal spores in the air is low, and their vigor is relatively high, so they are not suitable for germinating into mycelium; therefore, inoculation should not be done too early during cultivation. However, its mycelium, when established under low-temperature conditions, has strong resistance, grows robustly, and has a high survival rate. Therefore, inoculation can be carried out earlier by using a greenhouse, and after the mycelium germinates, the temperature is returned to normal to promote mycelial growth.
