What is the method of mushroom topdressing of edible fungi?

Mushroom manuring has many advantages, which can greatly improve the quality and quantity of edible mushrooms, so catching up with edible fungi to produce mushroom fertilizer is an important step to improve economic value. Today, the editor will share with you.

There are usually three ways to add nutrient solution: spraying, soaking and burrowing. The suitable time for spraying nutrient solution is when a large number of fruiting bodies appear. When spraying, we should pay attention to the sprinkler not facing the fruit body, but also pay attention to the "four do not spray": 1. Young mushroom buds should not be sprayed so as not to "swell to death". two。 Just picked mushrooms or mushroom remains do not spray, so as not to cause bacterial diseases. 3. Do not spray when the air humidity is too high. 4. Do not spray when the diseases and insect pests are serious in the mushroom shed.

The soaking method can be used for mushroom topdressing of edible fungi, which is mainly used for edible fungi planted in bags. After harvest, if the cultivation bag is seriously short of water, it can be soaked in the prepared nutrient solution until it is restored or close to the original weight.

Topdressing fertilizer for mushroom production of edible fungi can be used by irrigation method, which is mainly used on the fungus bed, and can be used when there are more mushrooms in the mushroom bed and excessive consumption of water and nutrients. The specific method is: punch the bacteria bed according to the hole distance of 10 centimeters, flood the prepared nutrient solution to the bacteria bed, and cover the soil after adding the nutrient solution.

When the concentration of nutrient solution is too high, it is not only difficult to absorb the hyphae, but also hinder or even damage the hyphae. When the concentration is too low, the goal of high yield can not be achieved. If the water content of the culture material is high, the concentration should be increased, and the ventilation rate should be increased after adding the nutrient solution. On the contrary, the concentration of nutrient solution should be reduced and the water consumption should be increased. The commonly used concentration of nutrient solution is: urea 0.3%-0.5%, potassium dihydrogen phosphate 0.2%, etc., we must grasp the principle of "less but diligent".

Edible mushroom topdressing fertilizer should be comprehensive nutrients should often alternate use of several nutrient solutions, so that the nutrition obtained by the entity is both comprehensive and reasonable. If hormones are used to stimulate the growth of edible fungi, they should be used after replenishing the nutrient solution.

Environmental change when the temperature is above 20 ℃, except for the varieties of high-temperature edible fungi, the nutrient solution can not be added. If the culture material has been contaminated by miscellaneous bacteria, be sure to remove the miscellaneous bacteria before adding the nutrient solution. In order to prevent miscellaneous bacteria pollution, we can also add a certain amount of bacteriostatic agents while adding nutrient solution to prevent the growth and spread of miscellaneous bacteria.

This is the end of the method of mushroom topdressing of edible fungi. I believe we all have a certain understanding. I hope this article will be helpful to you.
