Embodiment 1

[0017] A method for preparing a cultivation substrate for edible fungi by using potato residues, comprising the following steps: removing rotten potato residues, spreading the potato residues on an iron grid for dehydration, increasing ventilation to evaporate the water in the potato residues, and drying the air-dried potato residues. After the slag is crushed, it is sieved through a metal mesh sieve to remove the potato slag with a diameter greater than 4mm; mix 150g of potato slag, 150g of sawdust, 40g of bean cake powder, 660g of straw powder, and 10g of gypsum, add water until the water content is 62%, and then stir evenly Back bagging, 60 bags, autoclaved for 45 minutes and then cooled, respectively inoculated with 20 bags of Pleurotus eryngii, 20 bags of Pleurotus eryngii, and 20 bags of Hericium erinaceus. The conversion rate of Pleurotus eryngii can reach 78%, and the conversion rate of Pleurotus eryngii can reach 80%.

Embodiment 2

[0019] A method for preparing a cultivation substrate for edible fungi by using potato residues, comprising the following steps: removing rotten potato residues, spreading the potato residues on an iron grid for dehydration, increasing ventilation to evaporate the water in the potato residues, and drying the air-dried potato residues. After the slag is crushed, pass through a metal mesh sieve to remove the potato slag with a diameter greater than 4mm; mix 200g of potato slag, 100g of sawdust, 50g of bean cake powder, 620g of straw powder, and 20g of gypsum, add water until the water content is 60%, and then stir evenly Back bagging, 60 bags, autoclave for 60 minutes and then cool down, inoculate 30 bags of Pleurotus eryngii and 30 bags of Pleurotus eryngii respectively. %.

Embodiment 3

[0021] A method for preparing a cultivation substrate for edible fungi by using potato residues, comprising the following steps: removing rotten potato residues, spreading the potato residues on an iron grid for dehydration, increasing ventilation to evaporate the water in the potato residues, and drying the air-dried potato residues. After the slag is crushed, it is sieved through a metal mesh sieve to remove the potato slag with a diameter greater than 4mm; mix 200g of potato slag, 150g of wood chips, 45g of bean cake powder, 640g of straw powder, and 15g of gypsum, and add water until the water content is 61%, and then stir evenly Back bagging, 60 bags, autoclaved for 45 minutes and then cooled, respectively inoculated with 30 bags of Pleurotus eryngii and 30 bags of Pleurotus eryngii, the conversion rate of harvested Sanchao mushroom Pleurotus ostreatus can reach 80%, and the conversion rate of Pleurotus eryngii can reach 82% %.

Abstract

The invention discloses a method for preparing an edible mushroom culture medium from potato residue. The method comprises the following steps: removing rotted potato residue, spreading the potato residue on an iron net and dehydrating, enhancing the ventilation force so that the moisture content of the potato residue is evaporated, and grinding and sieving the air-dried potato residue; evenly mixing 15-20 parts of potato reside, 10-15 parts of saw dust, 4-5 parts of soybean cake powder, 62-66 parts of straw powder and 1-2 parts of gypsum, and adding water until the moisture content is 60-62% and then stirring evenly; bagging and sterilizing, thereby obtaining the edible mushroom culture medium. According to the method, the leftovers of agricultural and forestry products are taken as the major compost needed by cultivating the edible mushrooms, so that the edible mushroom culture cost is reduced; especially, the dosage of the potato residue and other raw materials is optimized so that the biological conversion rate can be increased and the potential value of the potato residue can be developed thoroughly; besides, the environmental pollution caused by the waste potato residue in the potato processing process is solved, the agricultural product processing industry chain is expanded, excellent ecological benefit is generated and considerable economic benefit is generated.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a method for preparing an edible fungus cultivation substrate by using potato dregs. Background technique [0002] Edible fungi refer to large fungi with huge fruiting bodies, fleshy or colloids that can be eaten by humans. They are delicious, nutritious, green and healthy, and are known as "mountain treasures". Edible fungus cultivation, as a good project with small investment, short cycle and quick results, has developed rapidly in China. my country's edible fungus industry has become an important industry in the planting industry, and its output value is second only to grain, cotton, oil, fruit, and vegetables, ranking sixth in the planting industry. According to the survey and statistics of China Edible Mushroom Business Network, the total output of edible fungi in my country reached 28.28 million tons in 2012, ranking first in the world, and th...
