Edible mushroom nutrition supplement has skills

In the process of edible fungus cultivation, reasonable supplement of various nutrients is an effective measure to increase the yield of edible fungi, but improper supplement will also be counterproductive. Therefore, when replenishing nutrition to edible fungi, we should pay attention to the following skills.

Pay attention to supplementary methods to supplement the nutrition of edible fungi are spraying, perfusion and soaking. The most commonly used method is to prepare a certain concentration of nutrient solution, combined with supplementary water to spray on the bacterial bed and bacterial block. When spraying in the bud stage, pay attention to spray the nutrient solution in the place where there is no mushroom or near the small mushroom bud, and wash the fruiting body with clean water after spraying. Spraying nutrient solution is best carried out at low tide, and the mushroom block and Linden wood can also be supplemented by soaking method, that is, it can be taken out after being fully absorbed in the prepared nutrient solution, generally after each tide mushroom harvest. The filling method can also be used on the bacterial bed, that is, the covering soil of the mushroom bed is removed, the funnel is inserted into the culture material, and then covered with nutrient solution. In general, the distance of the infusion point is about 10 cm, and each point is about 5 ml.

Pay attention to alternately replenishing different nutrient solutions such as glucose solution is carbon nutrition, urea is nitrogen nutrition, potassium dihydrogen phosphate is phosphorus and potassium nutrition, as well as other trace elements and organic nutrients. If one of these nutrients is used for a long time, it will be difficult to achieve the desired effect. Therefore, all kinds of nutrients must be supplemented alternately or mixed to meet the needs of edible fungi for different nutrients. On the mushroom bed, the nutrient solution with added nutrition should be applied first, and then the highly efficient nutrient agent should be applied, which is beneficial to the growth of fruiting body. If the hormone method is used to stimulate the growth of edible fungi, hormones should be used after supplements.

If the amount of nutrient solution is excessive at one time, it will make the culture material too wet, on the contrary, it will be extremely disadvantageous to the growth of mycelium. Therefore, when replenishing, we should look at the proper application of the humidity of the cultivation material. If the humidity of the culture medium is high, we should appropriately increase the concentration of the nutrient solution, reduce water consumption, and increase ventilation to dissipate moisture after application.

The raw materials for the production of topdressing liquid from the correct application of organic fertilizers shall not contain miscellaneous bacteria and eggs. The compost and feces used should be fermented or cooked and sterilized. The application of soybean milk, potatoes and other plant extracts should be used now, not for a long time.

Attention should be paid to the influence of the environment when the temperature is higher than 20 ℃, the mushroom hyphae are difficult to form fruiting bodies, so rehydration should be stopped. Glucose solution, soybean milk, human feces and urine should not be applied when the temperature is higher than 8 ℃. If the bacterial bed (block) has been infected with miscellaneous bacteria, it must be cured before rehydration.
