This article illustrates the fundamental techniques involved in the culture of banana or rice straw type of mushroom, Volvariolla volvacoa. The vegetable and Legume Crops Section of the Bureau of Plant Industry is now producing mushroom spawn in abundance.
Materials and Methods – I
Dry rice straws and banana leaves are the most common types of bleeding materials. However, other materials like cotton wastes, jute sacks, corn stalks, water hyacinth, sugar baggasse and abaca waste materials may also be used for bedding materials.
Sufficient water supply and soaking tank or any similar container are used. Plastic sheet of gauge No.6, empty cement bags and sacks are used to cover the beds.
1. Gather long, clean and well dried rice straws and banana leaves, preferably those that are still standing in the field. Avoid using old and contaminated bedding materials. 2. Bundle the bedding materials 6-8 inches in diameter. If rice straws are used, arrange butt ends together. 3. Cut the bundle materials 1.5 to 2 ft. long.
4. Soak the bundled materials in water for at least 3 hours but not more than 10 hours until enough moisture is absorbed by the materials. 5. Foundation as support for the bed.
6. Set the soaked-bundled materials, closely knit the together, evenly and compactly. 7. Water the bed well with the urea or ammonium sulfate at rate of 1-2 tbsp. per gallon of water. Add sugar at the rate of 33 grams per gallon of water to improve the yield of mushrooms. 8. Press the layer to level of surface. Stop watering when the water starts to drip off the bed. 9. Insert thumb-size spawns around the bed, four (4) inches from along the side and four (4) inches apart from each other. Never plant spawn at the middle of...
