Method for preparing mushroom culture medium

Abstract

The invention relates to the technical field of edible fungi production, in particular to a method for preparing a mushroom culture medium. The mushroom culture medium is prepared through the following steps: fermenting, drying and mixing waste beets, waste pears, waste potatoes, soybean product waste water, yeast, table salt, iron powder, charcoal powder and rice chaff ash. The fermentation product contains a large amount of nitrogen, phosphorus, and potassium, and is rich in microorganisms and organic matters; the nutrients are in a quick-acting state and easy to absorb by the mushrooms; the iron powder can absorb water and oxygen simultaneously and improve the content of oxygen in the culture medium; the charcoal powder is high in water absorption capacity and can retain water in the culture medium; meanwhile, the permeability and drainage property of the culture medium are also improved, and good growth space is provided for the mushrooms and microorganisms; waste vegetables are quick and convenient to get and process, and the waste vegetables are used as the medium, so that agricultural waste can be effectively developed and the culture cost of the mushrooms is reduced; therefore, good social, economic and environmental benefits can be achieved.

Description

technical field

[0001] The invention relates to the technical field of edible fungi production, in particular to a preparation method of a mushroom cultivation substrate. Background technique

[0002] Shiitake is a kind of edible fungus, which has been exported for many years. The output of shiitake in my country has reached more than 1 million tons in 1999, ranking first in the world. Shiitake is also a mushroom consumed worldwide. In my country, shiitake mushrooms are mostly sold as dry products, and some fresh products have also been exported in recent years. There are three basic methods of shiitake mushrooms: section tree cultivation, artificial mushroom tree cultivation and ground planting. With the continuous improvement of substitute material cultivation technology and the enhancement of people's awareness of forest protection, section tree cultivation has been rare in recent years. Our country's shiitake mushrooms mainly come from substitute Material cultivation, t...

Embodiment Construction

[0009] A method for making a cultivation substrate for shiitake mushrooms. The raw materials are weighed according to the following proportions: 20%-40% of discarded beets, 10%-15% of discarded pears, 20%-30% of discarded potatoes, 20%-50% of bean product wastewater, yeast 0.05%-0.08%, table salt 2%-5%, iron powder 0.2%-0.5%, charcoal powder 5%-10%, husk chaff ash 5%-8%.

[0010] Wash the sorted discarded beets, discarded pears, and discarded potatoes with water, chop them, and then use a tissue grinder to crush and grind them to obtain discarded vegetable residues. After mixing the discarded vegetable residues with soybean product wastewater, inoculate yeast for Fermentation, ferment for 22-25 days, the fermentation temperature is 30-32 ℃, the fermentation process is stirred 5 times a day, each time for 20 minutes, the stirring speed is 60r / min, to obtain the fermentation product, the fermentation liquid and the fermentation residue are separated to the greatest extent Separa...
