Problems solved by technology

[0003] The conventional cultivation formula of Pleurotus eryngii is mainly based on conventional agricultural and forestry raw materials such as bagasse, wood chips, corncobs, wheat bran, corn flour, soybean meal, etc. These raw materials are related to local agricultural production. For example, the main production areas of bagasse are Guangdong, Guangxi and Hainan However, the use of bagasse to cultivate Pleurotus eryngii in other areas has disadvantages such as high transportation and storage costs

Embodiment 1

[0013] What this embodiment uses is " Mincao No. 1 " pennisetum, chooses the pennisetum that grows 150 days, dries after cutting, and sets aside. The conventional cultivation materials used in production are used as the control of this experiment. On the basis of the formula of the control group, adjust the ratio of pennisetum grass powder to replace bagasse (replace bagasse 0, 50%, 75%, 100%) to design the experimental formula treatment. The design test formula is shown in Table 1. Three repetitions were set for each test formula, and 120 bags were made for each repetition.

Abstract

The invention provides a culture substrate for improving content of amino acids of Pleurotus eryngii. The substrate comprises the following raw materials in percentages by weight: 3.2-6.5% of bagasse,6.5-9.8% of Pennisetum alopecuroides, 22.2% of wood chips, 26% of corn cobs, 18% of wheat bran, 8.8% of corn flour, 9% of soybean meal, 1.8% of light calcium carbonate, and 1.2% of lime; the pH valueis adjusted to 9-11, and the sum of weight percentage of the raw materials is 100%. The fruiting bodies of Pleurotus eryngii produced on the culture substrate have substantially improved nutrition quality, the content of crude protein of Pleurotus eryngii is increased by 10-20%, the content of total amino acids is increased by 6.8-9%, content of delicious amino acids is increased by 6-8%, and theflavor of Pleurotus eryngii is substantially improved.

Description

technical field [0001] The invention belongs to the field of agricultural resource utilization and relates to a cultivation substrate for edible fungi, in particular to a cultivation substrate for increasing the amino acid content of Pleurotus eryngii by using Pennisetum eryngii. Background technique [0002] Pleurotus eryngii ( Pleurotus eryngii ), is a new species of rare edible fungus that integrates edible, medicinal and dietotherapy. Pleurotus eryngii is not only an ingredient for cooking food, but also has the effects of lowering blood fat, lowering cholesterol, promoting gastrointestinal digestion, enhancing the body's immunity, and preventing cardiovascular disease. To be long, very popular with people. Amino acid is an important nutritional component necessary for the human body. It is of great significance to maintain the normal physiology, biochemistry, immunity, energy saving, growth and development, metabolism and other life activities of the human body. The ...
