How to fertilize edible fungus? Matters needing attention in topdressing of edible fungi

Edible fungus is a kind of vegetable that we often see in our daily life, and its nutritional value is very high. For those who grow edible fungi, how to fertilize them? What should I pay attention to? Now I would like to introduce to you.

Pay attention to the method of adding. 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, you should pay attention to the spray head not facing the fruit body, and at the same time pay attention to the "four do not spray":

1. Young mushroom buds should not be sprayed to prevent them from "swelling to death".

2. Do not spray fresh mushrooms or residual mushrooms, 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 (room).

The soaking method is mainly used for bag-planted edible fungi. After harvest, if the cultivation bag is seriously short of water, it can be soaked in the prepared nutrient solution until it is close to the original weight. To add the nutrient solution by soaking, you only need to put the bacterial bag in the nutrient pool and press the heavy object, but the soaking time should not be too long. If the bacterial bag loses too much water, it can be soaked in several times.

The method of irrigation is mainly used on the bacterial bed, which can be used when there are more mushrooms in the bacterial bed and excessive consumption of water and nutrients. The specific method is as follows: punch the bacterial bed according to the hole distance of 10 boxes of meters, flood the prepared nutrient solution on the bacterial 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 effect is not obvious and can not achieve the purpose of high yield. Under the appropriate concentration, the addition of the nutrient solution should be determined according to the water content of the culture material: if the water content of the culture material is high, the concentration of the nutrient solution should be increased, the water consumption should be reduced, and the ventilation rate should be increased after adding. On the contrary, the concentration of nutrient solution should be reduced and the water consumption should be increased.

Nutrient solution nutrients should often be used alternately, so that the nutrients needed for physical growth are both comprehensive and reasonable. If hormone hormone is used to stimulate the growth of edible fungi, it should be used after replenishing the nutrient solution.

Attention should be paid to the changes of the environment when the temperature is above 20 ℃, the hyphae are difficult to form high-quality fruiting bodies. Except for the varieties of high-temperature edible fungi, 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 breeding and spread of miscellaneous bacteria.
