Detailed Explanation of the New Technology for One-Time Massive Mushroom Flushing of Oyster Mushrooms

The so-called new technology for massive mushroom flushing refers to the use of a supporting set of techniques to force a one-time high yield at the first flush of mushrooms. This is a further improvement and strengthening of "simulated industrial cultivation technology," and practice has shown that the results are very good and that it can be promoted for use. This technology mainly consists of five steps:

1. Carry out virus elimination treatment on the spawn. "Good seed produces good seedlings" is a truth everyone knows, but indefinite preservation of spawn and continuous, unlimited subculturing can lead to problems such as trait degeneration or naturally carrying viruses and pathogens. Therefore, by using advanced isolation techniques and early-stage tissue isolation techniques, pure hyphae free of viruses and pathogens are isolated, and then, by adjusting growth conditions such as the poorness or richness of the culture medium and the high or low cultivation temperature, the goal of further enhancing and improving the resistance and adaptability of the spawn is achieved. When the scale of cultivation production is relatively small and does not justify specialized virus elimination treatment, virus-free spawn can be introduced and used directly for production.

2. Adjust the nutrition of the substrate. Research has found that whether the substrate nutrition is rich or not directly restricts the amount of hyphae, the strength of the hyphae, and the number of mushrooms produced, and this is especially prominent in terms of hyphal resistance. In recent years, most people have only focused on selecting new varieties (strains) while neglecting attention to substrate nutrition. In recent years, the rational adjustment of substrate nutrition has become an important research topic, and the "Three-Dimensional Nutritional Essence for Edible Fungi" has been developed. This product has two methods of use, namely the mix-into-substrate type and the spray type. The former is mixed directly into the substrate, while the latter is sprayed directly on the mushroom bodies. When the two are combined, the general yield increase effect is about 30%, making it a technological product with obvious yield increase and stable effects at present.

3. Pay attention to disinfection and sterilization treatment of the cultivation environment. Outside the cultivation shed, on the basis of cleaning the environment, drugs such as carbendazim, lime sulfur mixture, and dichlorvos can be sprayed. Inside the cultivation shed, drugs such as Baibing Quwuzong and Shabingling are used for preventive application. If disease is found on the mushroom bodies, then according to the pathogen variety and degree of occurrence, drugs such as Huanggu Yipenling and Mushroom Shabingling are used to inhibit or kill them, achieving the goal of both preventing and eliminating diseases and ensuring that the product is green.

4. Extend the spawn-running time as much as possible. Extending the spawn-running time allows the hyphae to decompose and absorb more substrate nutrients and accumulate more biological energy, creating rich material conditions for massive mushroom flushing. Mushroom production is based on the number of hyphae, and the number of hyphae is premised on substrate nutrition and the length of the spawn-running time. Under the same conditions, if the spawn-running time is extended by more than 7 days, a yield increase effect of 20% to 30% can be obtained.

5. Implement foliar spraying of fertilizer. Although the fruiting bodies do not carry out photosynthesis, their growth still requires a considerable amount of nutrient elements. In particular, a deficiency of trace elements makes their nutrition incomplete and makes it difficult to increase yield. Practice has shown that spraying the Three-Dimensional Nutritional Essence for Edible Fungi can effectively solve this problem. Method of use: add one packet to each sprayer of water, adjust the water temperature to 25 to 32°C, and when the mushroom cap diameter is about 2 cm, spray directly. Spray 3 times in succession to achieve the goal of increasing yield, and it can also greatly increase the thickness of the mushroom caps and enhance their toughness.
