Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with specific embodiments.

[0024] 1. Preparation of Pleurotus ostreatus cultivation substrate

[0025] The following materials are weighed according to dry matter percentage: bagasse 79%, brewer's grains 10%, bran 5%, corn flour 2%, sugar 1%, lime 2%, gypsum 1%. Wherein, the brewer's grains should at least contain 24.5% of crude protein, 7.3% of crude fat, 13.8% of crude fiber, 3.8% of ash, 0.3% of calcium, 0.6% of phosphorus, 0.08% of potassium, 0.14% of magnesium, 0.9% of lysine, Methionine 0.5%, Cystine 0.4%, Arginine 1.5%, Isoleucine 1.4%, Leucine 1.7%, Phenylalanine 1.3%, Tyrosine 1.3%, Valine 1.6%.

[0026] Fully soak the bagasse in the above materials with water, pick up and spread out, spread other materials evenly on the surface of the bagasse, then mix evenly, control the water content of the mixed materials at 60% to 65%, and pile them up for fermentation 3 hours, form substrat...

Abstract

The invention discloses a medium for cultivating pleurotus ostreatus by using bagasse. The medium comprises the following components by dry weight percent: 75%-80% of bagasse, 10%-20% of beer gains, 5%-10% of bran, 2%-5% of corn flour, 0.5%-1% of sugar, 1%-2% of lime and 0-1% of gypsum. Furthermore, a preparation method of the medium for cultivating pleurotus ostreatus by using bagasse comprises the following steps: (1) fully soaking the bagasse by virtue of water; (2) evenly mixing with the beer gains, the brain, the corn flour, the sugar, the lime and the gypsum form a medium; (3) enclosing the medium into a culture bag; and (4) sterilizing and cooling the culture bag with the medium for later use. According to the preparation and application methods of the medium for cultivating pleurotus ostreatus by using bagasse disclosed by the invention, the bagasse is utilized in a high-valued manner; the production cost of the pleurotus ostreatus is reduced; and meanwhile, the quality of the pleurotus ostreatus is improved.

Description

technical field [0001] The invention relates to a cultivation technology of flat mushrooms, in particular to a preparation method and use of using bagasse as a substrate for cultivation of flat mushrooms. Background technique [0002] Pleurotus otreatus, also known as Pleurotus ostreatus, is rich in nutrients and has good edible and medicinal value. It is one of the widely cultivated edible fungi in my country. For a long time, the cultivation of Pleurotus ostreatus mainly takes cottonseed hulls, sawdust, wheat straw, corncobs, other agricultural by-products or leftovers as the main raw materials. In recent years, forest resources have become increasingly scarce, cottonseed husks and corncobs have been used in many ways, and crop straws have been returned to the field, resulting in an increasing cost of raw materials for Pleurotus ostreatus, which has seriously affected the economic benefits of Pleurotus ostreatus cultivation. New materials are imperative. [0003] Bagasse...
