What are the precautions for topdressing edible fungi?
Edible fungi are a common type of fungal vegetable in our daily lives. Common edible fungi include shiitake mushrooms, oyster mushrooms, wood ear mushrooms, and others. Their cultivation area is quite widespread in our country. When growing edible fungi, because they differ from other ordinary vegetables, their management is also different. In particular, when topdressing to supplement nutrients for edible fungi, there are some points we need to pay attention to. Below, the editor brings you the precautions for topdressing edible fungi. Let's take a look!
1. Topdressing methods
When topdressing edible fungi, methods include spraying and soaking, among which the most commonly used method is spray fertilization. First, prepare a suitable nutrient solution and combine it with watering, spraying it evenly and comprehensively over the bed. When topdressing, also pay attention to the growth stage of the edible fungi. For example, during the young mushroom stage, first water to moisten the fruiting bodies, then spray the nutrient solution near the young mushrooms, without touching the young mushrooms. If using fungus blocks or fungus sticks, then they should be appropriately soaked to ensure they absorb sufficient nutrient solution and promote growth.
2. Nutrient balance
When applying the nutrient solution, pay attention to the nutrient balance of the solution, and rotate and alternate the application of different nutrient solutions to ensure that the various nutritional needs of the edible fungi are met. Do not supplement a single nutrient over the long term, as this is not very helpful for the growth of edible fungi, and yield cannot be guaranteed. When fertilizing, first spray the nutrient solution that supplements nutrients on the fungus bed, then spray the nutrient agent. This can both ensure the growth of the fruiting bodies and meet the nutritional needs of the edible fungi. If the nutrient solution is a hormone-based one, then the hormone should be used after spraying the nutrient agent.
3. Pay attention to dosage
The dosage of the nutrient solution is also very important, and it must be kept within an appropriate range, neither too much nor too little. If sprayed too much, it will increase the humidity of the culture material and have a very serious impact on the growth of the mycelium. If too little, it cannot meet the nutritional needs of the edible fungi, and not only will mycelial growth be hindered, but fruiting body growth will also be very slow. Therefore, when spraying the nutrient solution, we should observe the humidity of the culture material. If the humidity is relatively high, then increase the concentration of the nutrient solution and reduce the dosage. Conversely, reduce the concentration and increase the dosage. After application, do a good job of ventilation to avoid excessive humidity affecting the growth of the edible fungi.
4. Pay attention to the environment
When applying the nutrient solution, we should pay attention to the surrounding environment. If the temperature reaches above 20 degrees, it is very difficult for edible fungi to form fruiting bodies, and supplementation should be stopped at this time. Because the temperature is unsuitable, the edible fungi will stop growing, and supplementing with nutrient solution is also a waste; instead, it increases cultivation costs. Nutrients such as glucose and dilute manure water also cannot be applied in an environment above 8 degrees. Finally, we should also pay attention to the growth of the edible fungi. If contaminated fungi or pests and diseases are found, then nutrient solution can only be supplemented after they are cured.
The above is a brief introduction to the precautions for topdressing edible fungi. The nutritional needs of edible fungi are relatively high. And unlike ordinary vegetables, which only need topdressing with inorganic and organic fertilizers, growing edible fungi also requires preparing a dedicated nutrient solution, so everyone must pay close attention.
