ВДАУ

• Several years ago the Polish mushroom cultivators have gift this presentation to the beginning colleagues from Ukraine.

• Sergey Vdovenko from Donetsk University has translated it to the Ukrainian language.

• Now I have translated it into English for my mushroom friend - Mickey Foley.

substrate manufacture cultivation

+

Distance not less then 1000 m

15 - 25 kg

block 15 x 30 x 55 cmapproximately 16 - 18 kg

The most simple cultivation chambers

Optimum hangar length 15 m (max 20 m)

• Temperature: 12-24 0C

The basic technological parametres

• Relative air humidity: 70-95%

• Illumination: 200-500 lux 8-10 hour/day

Air movement organization

16-18 kg per 1m3

Variants of ventilation systems

Forced and exhaust ventilation

Exhaust ventilation

Maximum wind speed

10 cm/sec

Result of too high wind speed and too

low air humidity

First 3- 4 days 20-22 0C Rh = 70-75%

No ventilation

colonization

aging15-17 0C

Rh = 85-95% min ventilation

High CO2 level

Too high air humidity Too low air humidity

CO2

[CO2] = 0,06-0,08 %

Illumination ≥ 200 lux 8-10 hours/day

CO2 excess or light shortage

[CO2] > 0,1 %

The first fruiting wave

peel it

regeneration (20-220C, Rh = 95-100%) 3- 4 days without ventilation

13-170C, 80-85%

2 - 3 weeks

The second fruiting wave

Oyster mushroom spores are strong allergen for 60 % of people

Fruit bodies storage in the refrigerating chamber

Fruit bodies without a stipe

1-2 0C

Vellus ≤ 2 cm

16 kg 2,5 - 3 kg in each box

2001-2004

Oyster mushroom strains

К-12

Other strains

It is possible to grow up mushroomsoutdoor on the substrate blocks after 1 - 2

waves of fruiting- at remote territory only!
