Composition and method of preparation of substrate

The need for raw materials for the preparation of the substrate .


When organizing mushroom cultivation is important to calculate the need for starting materials for preparing the substrate . Basic parameters for this calculation - the loss of weight and dry matter for a period of spontaneous fermentation, which depend on the length and composition of the fermentation substrate . The weight loss ranged from 30 up to 50% . When the old traditional composting process for 25 - 28 days the loss of dry substance is 45 - 50%; for short composting preliminary moistening of the straw fermentation period for 9 - 12 days - 30 - 35, when fermented for 16 - 17 days - 35 - 40% .





12 . Scheme preparation of a synthetic substrate based on rice straw


Day composting

Treatment type

Additives per 1 ton of dry straw

1 - 6-I

Chopped straw into pieces of length 10 - 20 cm, moisturizing, adding a nitrogen-containing materials, push-ups

Water - about 2000 liters, urea - 20 kg

7

Adding nitrogen-containing materials, mixing them with a straw. Formation collar size 1,7x1,7 m

Broiler litter - 200 kg urea - 10 kg

12 - 13 th

Adding organic material, humidification to a moisture content of 70% . 1st cutaways

Broiler Litter - 100 kg of water, if necessary

15 - 16 minutes

Adding gypsum and superphosphate . 2nd cutaways

Gypsum - 50 kg superphosphate - 3 - 5 kg water to moisten the dry places

18 - 19 minutes

3rd cutaways with advanced control of water content

Water - with a moisture content below 70%

21 - 22 minutes

4th cutaways. Filling tunnel pasteurisation . If the substrate appearance is not ready, it is allowed to continue fermentation for further 1 - 2 days
