|4. Straw mushroom cultivation in beds|
The materials needed to cultivate straw mushrooms in beds are the following:
1. Rice straw, or dried water hyacinth as the growing substrate. (Note: With rice straw, use the bottom portion of the stalk left in the fields after harvest. The bottom portion is preferred because it absorbs and retains water better than the upper portion harvested with rice grain and offers a more humid atmosphere for mushroom growth than the tops of the stalk which dry rapidly.) Other substances that may be used include: banana tree trunks and leaves, maize residues, mung bean husks and para rubber tree pulp.
2. Supplementary food made from dry chicken, pig, cattle or buffalo manure mixed in a 1:1 ratio (by volume) with chopped or shredded dry water hyacinth or rice straw. The mix should be watered until thoroughly moistened. Cotton and/or kapok may also be added to the mixture.
3. Spawn. Choose spawn that is sweet smelling and healthy looking with long white mycelium threads visible throughout the growing substrate. (Note: For more information concerning the purchase and handling of mushroom spawn refer to Appendix F.)
4. Watering can and water. Be careful not to use chlorinated water, as it will kill the mushroom spawn. If only chlorinated water is available, it can be dechlorinated by collecting it in a jar and allowing the water to sit for two days. The chlorine dissipates and the water is acceptable for use.
Use of the wooden mold
5. Wooden mold, approximately 80-120 cm long, 40 cm wide at the base, 35 cm wide at the top (to ease removal of the wooden mold once the bed has been constructed).

6. Clear plastic sheet and rice straw to be used to cover the beds.
