Latest Roundup of Precautions for Topdressing Edible Fungi

Edible fungi are a common type of fungal vegetable in our lives. Common edible fungi include shiitake mushrooms, oyster mushrooms, wood ear mushrooms, and others. Their cultivation area is quite extensive in our country, and 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 together!

1. Topdressing Methods

When topdressing edible fungi, there are methods such as spraying and soaking, among which the most commonly used method is spray fertilization. First, prepare a suitable nutrient solution, combine it with watering, and spray 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 they are fungus blocks or fungus sticks, then they should be properly soaked to ensure they absorb sufficient nutrient solution and promote growth.

2. Nutritional Balance

When applying the nutrient solution, pay attention to the nutritional balance of the nutrient solution, and pay attention to alternating 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 it is not very helpful for the growth of edible fungi, and the yield cannot be guaranteed either. When fertilizing, first spray the nutrient solution that supplements nutrition on the fungus bed, and 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, 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, not too much or too little. If sprayed too much, it will increase the humidity of the culture material and cause 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. So when spraying the nutrient solution, we should pay attention to observing the humidity of the culture material. If the humidity is relatively high, then increase the concentration of the nutrient solution and reduce the dosage; on the contrary, then 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 the nutrient solution is also a waste, and instead increases the cultivation cost. Nutrients such as glucose and diluted 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 contamination by foreign bacteria or pests and diseases is found, then the 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. Also, unlike ordinary vegetables, which only need inorganic and organic fertilizer topdressing, growing edible fungi also requires preparing a dedicated nutrient solution, so everyone must pay close attention.
