Consulting: Hello experts! A batch of Agaricus bisporus was planted on China's Qing dynasty. After inoculation, the mycelium grew very thick. It was recently prepared to cover soil. However, it was discovered that the hyphae grew about 5 centimeters long and the hyphae grew paler. Want to ask what is the reason and solution?
Answer: The possible causes and solutions are as follows:
One is that the cultivation material is too wet.
The solution: According to the degree of wet material, use a stuffy wooden stick or the like to poke a hole every 3 to 5 centimeters on the material surface, poke it to the bottom of the material, and increase the ventilation of the mushroom house. Promoting the dehumidification of the culture material and increasing the oxygen content of the material basically rejuvenate the growth of the hyphae. Fundamental measures: Pay attention to control the moisture content when stacking materials. If the moisture content of the material is found to be too high when it is turned, it should be spread out and then dried again. The water content of the culture material with good fermentation should be 60-65%.
The second is to cultivate too much nitrogen in the feed.
Solution: If it is light, you can poke holes in the material surface to strengthen the ventilation; if it is particularly serious, for example, if the piled material can smell very strong ammonia, we must turn the culture materials back to the beach, cool the beach, etc. After the taste is dispersed, adjust the humidity, and then make the bed again. Fundamental measures: The amount of nitrogen fertilizer added during the construction of the heap can not be too much, especially inorganic nitrogen such as urea, should be added during the first turn, and the amount should not exceed 1% of the total culture material. Before the bed is piled up, the ammonia smell must be heard before the bed is laid, and the bed must be inoculated before the smell of ammonia is substantially heard.
The third is insect pests.
Solution: If it is determined to be a locust hazard, a more thorough solution that can be taken is fumigation with aluminum phosphide. We can use 56% aluminum phosphide tablets per cubic meter by 4 g dose closed fumigation 24 hours or so. Pay special attention, because aluminum phosphide is highly toxic, so wear a thick mask when you place it and quickly quit, fumigation must be fully removed after the removal of toxic gases. Fundamental measures: during the stacking process, one or two abattoirs are sprayed evenly within the material, and the mushroom housing surfaces, walls, roofs, bed frames, and other utensils are sprayed and killed during the empty period of the mushroom house. Agent prevention in advance. Http://Content/4bda3090-fef8-4afd-940e-be7f55fd5d13?cType=2
