Edible fungus pay attention to "four to"
In the later stages of mushroom cultivation, growers often apply nutrient solutions to boost productivity and improve yield. However, the effectiveness of this practice depends heavily on how the solution is applied. Improper application can lead to adverse effects, such as reduced growth or even damage to the crop, resulting in financial loss for the grower.
First, it's important to choose the right method of application. There are three common ways: spraying, soaking, and irrigation through injection points. Spraying is most effective when a large number of fruiting bodies have developed. When doing so, avoid directing the nozzle directly at the mushrooms. Follow the "four no-spray" rules: do not spray young mushroom buds to prevent swelling, avoid spraying after harvesting or when there are leftover mushroom remnants to prevent bacterial infections, don’t spray when humidity is too high, and refrain from spraying if the growing area has serious pest or disease issues.
The soaking method is suitable for bag-grown mushrooms. After harvesting 1-2 flushes of oyster mushrooms, if the bag appears severely dehydrated, it can be soaked in a prepared nutrient solution until it regains its original weight. Once soaked, gently press the bag to ensure even absorption, but avoid leaving it in the solution for too long. If the bag is still losing water, divide the soaking process into multiple sessions.
The injection method is typically used for mushroom beds. It’s ideal when the bed has many mushrooms and is experiencing high demand for water and nutrients. The process involves drilling holes every 10 cm into the bed, then pouring the nutrient solution into the holes before covering with soil.
Second, the concentration of the nutrient solution must be carefully controlled. Too high a concentration can hinder mycelium absorption and may even harm the fungi. Too low a concentration, on the other hand, will not provide enough nourishment, leading to poor yields. The appropriate concentration also depends on the moisture level of the growing medium. If the medium is already wet, increase the concentration to reduce excess water and improve ventilation afterward. Conversely, if the medium is dry, lower the concentration to help retain moisture.
Third, the nutrient solution should contain a balanced mix of essential elements. It's advisable to alternate between different types of solutions to ensure the fruiting bodies receive a well-rounded diet. If using growth hormones, they should be applied only after the nutrient solution has been added to maximize effectiveness.
Lastly, environmental conditions must be closely monitored. At temperatures above 20°C, mycelium struggles to form high-quality fruit bodies, except for heat-tolerant species. In such cases, avoid adding any nutrient solution. If the growing medium is already contaminated, remove the affected areas first before applying the solution. To prevent microbial contamination, you can also add a small amount of bacteriostatic agent along with the nutrient solution.
