Detailed Explanation of Key Technical Points for "Explosive Fruiting" of Edible Mushrooms

The so-called "explosive fruiting" refers to a technique in edible mushroom cultivation whereby, through artificial regulation, the mycelium colonization period is extended as much as possible to accumulate higher biological energy, so that once fruiting begins, an "explosive" momentum is formed. This transforms the original fruiting process, which lasted as long as 5 months, went through 3 to 4 flushes, and had a biological efficiency of 100%, into one where, once "explosive fruiting" occurs, the total yield is produced all at once, with biological efficiency exceeding 160%, greatly improving the input-output ratio. Key technical points of "explosive fruiting":

1. Perform virus elimination treatment on the mushroom spawn or introduce virus-free spawn. Spawn that has been subjected to virus elimination treatment by scientific methods will not carry any pathogens itself, and during the virus elimination process, after continuous high-temperature and low-temperature conditioning combined with constant changes of the culture substrate, the resistance of the spawn is greatly enhanced, and problems such as strain degeneration will not occur.

2. Adjust the nutritional components and levels of the culture material. For example, when cottonseed hulls (for oyster mushroom, enoki mushroom, king oyster mushroom, etc.) are used as the main culture material, 1 bag of edible mushroom three-dimensional nutritional essence can be added per 250 kg; when corncobs or waste cotton (for oyster mushroom, shaggy ink cap mushroom, etc.) are used as the main culture material, 1 to 2 bags of edible mushroom three-dimensional nutritional essence can be added per 250 kg; when wheat straw (for button mushroom, straw mushroom, etc.) is used as the main culture material, 1 to 2 bags of edible mushroom three-dimensional nutritional essence can be added per 250 kg; when sawdust (for shiitake mushroom, white lingzhi mushroom, shaggy ink cap mushroom, etc.) is used as the main culture material, 2 bags of edible mushroom three-dimensional nutritional essence can be added per 250 kg.

3. Strict disinfection and sterilization treatment of the cultivation environment. (1) After cleaning up the production environment, use Baibingquwuzong to disinfect and sterilize the spawn-running room and fruiting site; (2) Add fungicidal drugs such as Gubingxiao to the base material, so that the spawn-running success rate can reach 98%.

4. Strengthen mycelium post-ripening culture so that more biological energy is stored and the material conditions for explosive fruiting are in place. Within a certain range, under the same conditions of variety, culture material, etc., for every 7 days the post-ripening period is extended, the biological efficiency of the first flush increases by about 30%. Generally, on the premise of adjusting the nutrition of the culture material, the post-ripening time of the mycelium should be extended as much as possible, generally around 15 days is appropriate.

5. During the fruiting stage, combine with "foliar fertilization" to enhance the effect of "explosive fruiting". Taking oyster mushroom as an example, generally when the cap diameter reaches 2 cm, mix the edible mushroom three-dimensional nutritional essence into warm water at 25°C to 32°C and spray it directly on the fruiting bodies; spraying 3 times per flush can achieve the best yield-increasing effect.
