Problems solved by technology

[0003] The landfill treatment of lactic acid fermentation residues takes up a lot of land resources and pollutes the environment; while the incineration treatment has a low calorific value, consumes a lot of energy for equipment operation, and has high treatment costs; as feed raw materials, it is easy to produce secondary pollution during transportation, and the cost of sterilization is high; Lactic acid extraction wastewater treatment also requires larger wastewater treatment facilities

Embodiment 1

[0024] 1. Preparation of cultivation substrate

[0025] First soak 54kg of rice straw in lime water with a mass fraction of 4% for more than 8 hours, drain it, and cut the soaked rice straw to 3cm, then mix the rice straw with 40kg of lactic acid fermentation residue, 1kg of gypsum powder, 1kg of sucrose, 4kg of lime is mixed to form a dry material, and then the lactic acid extraction waste liquid is added for mixing to obtain a mixture. The added lactic acid extraction waste liquid makes the water content of the mixture 60%. Carry out sub-packaging, each fungus bag is 0.5kg, one end of the fungus bag is tied tightly with a rope, and sterilized at a temperature of 126°C for 2 hours. The PH value of the sterilized mixture is between 6 and 7.5, which is the edible fungi. Cultivation substrate.

[0026] 2. Cultivation of Pleurotus ostreatus

[0027] (1) Put the sterilized cultivation medium in the inoculation room, and sterilize it by ultraviolet light for 1 hour. When the temp...

[0032] 1. Preparation of cultivation substrate

[0033] First, soak 64kg of straw in lime water with a mass fraction of 4% for 8 hours, drain it, and cut the soaked straw to 3cm, then mix the chopped straw with 30kg of lactic acid fermentation residue, 1kg of gypsum powder, 1kg of sucrose, and 4kg of sucrose. Lime is mixed to form a dry material, and then lactic acid extraction waste liquid is added for mixing to obtain a mixture. The added lactic acid extraction waste liquid makes the water content of the mixture 65%. Separately pack, each fungus bag is 0.6kg, one end of the fungus bag is tied tightly with a rope, and then sterilized at a temperature of 128°C for 1.5h, the PH value of the sterilized mixture is between 6 and 7.5, which is edible fungus cultivation substrate.

Abstract

The invention discloses a cultivation substrate of an edible mushroom, a preparation method of the cultivation substrate and a cultivation method of the edible mushroom. The cultivation substrate of the edible mushroom comprises a carbon source, a nitrogen source, water and other auxiliary materials and is characterized in that all or a part of the nitrogen source is lactic acid fermentation residue; and all or a part of the water is replaced by lactic acid extract waste liquid. The lactic acid fermentation residue and the lactic acid extract waste liquid serve as raw materials of the cultivation substrate of the edible mushroom, and are recycled completely, discharge of waste residue and waste water is reduced, the cultivation substrate is appropriate to industrial production and has better social and economic benefits, and a new approach is provided for utilization of the lactic acid fermentation residue and the lactic acid extract waste liquid.

Description

technical field [0001] The invention belongs to the field of cultivation of edible fungi, and in particular relates to a cultivation substrate of edible fungi, a preparation method thereof and a cultivation method of edible fungi. Background technique [0002] After the lactic acid fermentation is completed, the fermentation liquid is firstly separated from solid and liquid, and the separated residue is mainly disposed of by landfill and incineration, and a small part is sold as feed raw materials. The separated clear liquid continues to be extracted with lactic acid, and the waste liquid after extracting lactic acid is treated and then discharged. [0003] The landfill treatment of lactic acid fermentation residues takes up a lot of land resources and pollutes the environment; while the incineration treatment has a low calorific value, consumes a lot of energy for equipment operation, and has high treatment costs; as feed raw materials, it is easy to produce secondary pollu...
