Pleurotus eryngii culture medium and culture method thereof

Abstract

The invention relates to a pleurotus eryngii culture medium and a pleurotus eryngii culture method. The culture medium is prepared by the following steps of: a, mixing 72 to 79 mass percent of miscanthus floridulus which is cut into particles with diameters of 1 to 2 cm, 17 to 22 mass percent of bran, 2 to 4 mass percent of white sugar, 0.9 to 1.1 mass percent of gypsum powder and 0.9 to 1.1 masspercent of lime; and b, uniformly stirring the components in the step a, and adding water to prepare the culture medium with the water content of 65 to 75 percent and the pH of 7.5 to 8. The pleurotus eryngii culture method comprises the following steps of: preparing the culture medium, placing the culture medium with the water content of 65 to 75 percent into a culture bottle and sealing the culture bottle for sterilization; opening sealing paper and implanting strains into the culture medium in the culture bottle with an inoculating tool; and performing inducement to primordium and fruitingmanagement. The pleurotus eryngii culture medium and the pleurotus eryngii culture method have the advantages that: produced pleurotus eryngii is large and delicious, and has high yield; the culture method is simple; as the miscanthus floridulus is adopted as the main raw material of the culture medium and has a wide source and low cost, the production cost of the pleurotus eryngii is lower; and a production environment is clean and has no off-odor, so workers can work in the sanitary and clean environment.

Description

technical field [0001] The invention relates to a cultivation method for producing Pleurotus eryngii by using the five-jointed awn as the main raw material of the cultivation base. Background technique [0002] Wujiesang (alias awn stalk, big dish grass, big thatch) is distributed in Guangdong, Guangxi, Taiwan, Fujian, Jiangxi, Hunan, Sichuan, Guizhou, Yunnan, Jiangsu, Zhejiang, Anhui and other places in China; it is also found in Australia. [0003] Morphological characteristics Perennial herb. Fibrous root system. The stem is thick, the plant height is 2-4 meters, with white powder under the joint, glabrous, the stem is 1-1.5 cm thick. There are rhizomes underground, with scale-like leaves. Leaves lanceolate, 25-80 cm long, 1.5-4 cm wide, leaf sheaths without or only sparsely ciliated at the margin. Each plant has more than 10 to 25 leaves, dark green. The panicles are broad and dense, 30-50 cm long, the main axis extends to the tip of the inflorescence or at least to...

Problems solved by technology

But its disadvantage is that the formula of the culture medium not only has many raw materials, but also has high production cost, and the ingredients are complicated, and the production environment has a strong odor, which has a great impact on the physical and mental health of the staff.
