How to fertilize edible fungi scientifically?

Edible fungus is a large fungus that can be used for human consumption. Edible mushroom industry has become an important industry in China's planting industry. The domestic market has great potential. Correct fertilization is an important measure to grab the high yield of edible fungi and improve the quality of edible fungi. The function of fertilizing is to make up and adjust the nutritional composition and to create favorable conditions for the continued high yield of edible fungi. So how to fertilize edible fungi scientifically?

1. Fertilize the nurturing materials

At present, the water intake of cottonseed hulls is very low, and there is a lack of nutrition. if there is no other increase in nutrition, it is very difficult to improve the output value, which is why many mushroom farmers report that their output value is much lower than before. Organic fertilizer should be the main fertilizer in the cultivation guess, and the amount of chemical fertilizer can be relatively less. Organic fertilizer has comprehensive nutrition and can provide omni-directional nutrition supply for the growth of edible fungus hyphae, especially in the later stage of mushroom emergence, which is particularly outstanding. The composition of chemical fertilizer is simply absorbed and used by mycelium, which can be combined with organic fertilizer.

The organic fertilizers often used by edible fungi are livestock and poultry manure, bean cake, cotton cake, corn flour, wheat bran, rice bran, etc., according to the nitrogen content of the material, can participate in 10% to 30%. Chemical fertilizers generally have potassium dihydrogen phosphate, magnesium sulfate, urea, compound fertilizer, edible fungus special fertilizer, etc., the participation amount is generally 0.1%-0.5%, can not participate too much, otherwise it will lead to poor mycelium growth.

2. Fertilize the nutrient solution after mushroom production

In the late stage of mushroom emergence, the nutrition of cultivation materials can no longer provide omni-directional nutrition supply for the growth of edible mushroom hyphae. Mushroom farmers often adopt various methods to increase nutrient solution to make up for nutrition. There are generally three ways to increase the nutrient solution of edible fungi: 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 that the sprinkler is not facing the fruit body.

At the same time, we should also pay attention to the "four do not spray":

① young mushroom buds do not spray to avoid its "swelling to death".

② has just picked mushrooms or do not spray the remains of mushrooms to avoid causing bacterial diseases.

③ does not spray when the air humidity is too high.

④ mushroom shed does not spray when the diseases and insect pests are serious.

The soaking method is mainly used for bag-planted edible fungi. After harvest, if the culture bag is in a state of severe water shortage, it can be soaked in a prepared nutrient solution until it recovers or is close to the original amount.

The method of irrigation is mainly used in the bacterial bed, which can be used when there are more mushrooms in the bacterial bed and the consumption of water and nutrition is too high. 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.

3. Pay attention to the problems that should be paid attention to:

The first is to adopt different fertilizing methods according to different species. If the method is not applied properly, it will pull out the seedlings and encourage them.

The second is that in the process of fertilizing, all kinds of fertilizers should be used alternately, which is especially important for some inorganic fertilizers with simpler nutrients.

The third is that the application of fertilizer should be appropriate, do not apply too much at one time, or the concentration of fertilizer solution is too high, so as to avoid the unlucky effect on the growth of mycelium.

The commonly used concentration of nutrient solution is: urea 0.3%-0.5%, potassium dihydrogen phosphate 0.2%, etc., we must grasp the criterion of "less but diligent"; fourth, all kinds of fertilizer solution should be used now and should not be released for a long time to avoid fertilizer solution metamorphosis.
