Mushroom Spawn Bag Cultivation Methods and Detailed Steps

AbstractMushroom spawn bags are generally inoculated using the multi-point method, that is, inoculating 3-4 points around the substrate inside the bottle at appropriate distances, then adding a small piece of spawn on the surface of the substrate. They need to be cultured in the dark at 24-28°C for 7-10 days. When the mycelium germinates and grows into colonies about 4 cm in diameter, the mycelium must be manually stirred immediately, and after waiting 25-30 days it can grow to fill the bottle mouth.

1. The mushroom is a relatively common food in daily life, with very high edible value and a delicious taste. Therefore, it is sold in many places in our country and is deeply loved by consumers. Mushroom spawn bags are generally inoculated using the multi-point method, that is, inoculating 3-4 points around the substrate inside the bottle at appropriate distances, then adding a small piece of spawn on the surface of the substrate.

2. The spawn bag needs to be cultured in the dark at 24-28°C for 7-10 days. When the mycelium germinates and grows into colonies about 4 cm in diameter, the mycelium must be manually stirred immediately. During stirring, the mycelium at the inoculation points is broken and stimulated, and because opening the bottle mouth actually increases oxygen for the mycelium, it is beneficial to vigorous mycelial growth. Generally the entire culturing process takes 25-30 days to grow to fill the bottle mouth.

3. When planting, it is necessary to check whether free ammonia is still present in the substrate. Generally, you can grab 1 handful of the substrate from the middle layer of the mushroom bed and smell it with your nose. If it has a pungent ammonia smell, it is not suitable for spawning. At the same time, you also need to check the temperature of the middle layer of the substrate. You can insert a thermometer into the substrate. If the substrate temperature is below 30°C, spawning can be carried out.

4. Generally when spawning, the spawn blocks should not be buried too deep. The suitable depth for the spawning holes is 3-5 cm. The spawn blocks need to be left slightly exposed above the surface of the substrate, and the surrounding substrate should be slightly pressed down to make the spawn and the surrounding substrate fit tightly together, which is beneficial for the spawn to colonize.

5. During the growth process, it is necessary to do a good job of environmental sanitation, while removing sources of pests and diseases, and promptly cleaning up garbage, especially rotten mushrooms, mushroom roots and discarded substrate, to avoid the growth of contaminating microorganisms or adult insects coming to lay eggs. Generally, eliminating sources of pests and diseases helps reduce pests and diseases. When pests and diseases occur, light traps can be used for trapping and killing. The adults of mushroom gnats and mushroom flies are phototactic, and generally black light lamps or high-voltage electrostatic insect-killing lamps can be used for trapping and killing.

6. Alternatively, a 1500-fold dilution of 5% fipronil can be sprayed directly onto the spawn bags. The pesticide fipronil has very good contact-killing, stomach-poisoning and systemic translocation effects on mushroom gnats and mushroom flies. If larvae cause severe damage, it needs to be sprayed once more after 3 days. Generally, as long as you have mastered the cultivation techniques for mushroom spawn, it is actually very simple to carry out.
