Abstract

The disclosure describes a process for the culture of Quebec Pleurotus Super Mushroom. For this purpose, a substrate comprising straw, wood chips from broad-leaved trees, crushed shelled ears of corn, vermiculite, Japanese millet, mixed cereal grains, lime, micro-cel, is seeded with the Quebec Pleurotus inoculum. The mixture is maintained at a humidity of 75 to 85% and a pH of 6.2 to 6.8. The system is given a photoperiod of 2.5 hr at a light intensity of 125 lux. Incubation temperature is maintained at 22° C. and fruiting temperature at about 14° C. to 21° C. This enables to obtain within 8 to 12 days of complete development, mushrooms of the class Basidiomycetes, Agaricales of the Pleurotaceae family, from the mushroom 107-Aa G. MYCOLA Inc. This mushroom is an excellent food, loaded with aromatic principles and enables to be prepared in many ways. In addition, it can be used as a laboratory tool, for teaching biology and botany, or has decorative use in a small interior garden. It requires only water and care to maintain a high degree of humidity. Between each production (growth of mushrooms) it can be refrigerated.

Claims

1. A substrate for the cultivation of mushrooms including Quebec Pleurotus Super Mushroom, said substrate consisting essentially of a homogeneous mixture of:

(a) 300 to 200 units of straw;

(b) 200 to 50 units of wood chips from broad-leaved trees;

(c) from 250 to 50 units of crushed shelled ears of corn;

(d) from 100 to 40 units of vermiculite;

(e) from 50 to 10 units of Japanese millet;

(f) from 50 to 15 units of mixed cereal grains;

(g) from 10 to 5 units of lime;

(h) from 30 to 20 units of micro-cel; and

(i) from 50 to 10 units of Quebec Pleurotus inoculum.

2. The substrate of claim 1, wherein the said straw is dried grass straw of 5 to 10% humidity, finely chopped to lengths of between 1.5 and 4.5 cm.

3. The substrate of claim 1, wherein the said wood chips from broad-leaved trees are obtained from Betula papyrifera or Populus tremuloides.

4. The substrate of claim 1, wherein the said crushed shelled ears of corn contain less than 2% of grain particles and are seived to retain only particles able to pass through 5.0 mm diameter pores.

5. The substrate of claim 1, wherein the said vermiculite has been subjected to a temperature sufficient to dilate the plates.

6. The substrate of claim 1, wherein the said mixed cereal grains contain equal parts of oats, barley and wheat.

7. A process for the cultivation of Quebec Pleurotus Super Mushroom, which comprises:

obtaining a substrate of claim 1, said substrate being seeded with said Quebec Pleurotus inoculum,

maintaining the said substrate at a humidity of 75 to 85% and a pH of 6.2 to 6.8,

permitting said substrate to undergo a photoperiod of about 2.5 hours at a light intensity of 125 lux, and

incubating the mixture at 22°

C. followed by fruiting at about 14°

C. to 21°

C. for about 8 to 12 days.
