Growth environment of Pleurotus eryngii

Growth environment of Pleurotus eryngii

The growing environment of Pleurotus eryngii is a mushroom that many people like to eat. Pleurotus eryngii is a kind of mushroom that many people like to eat, because its meat is thick and delicious, and it has many very good eating effects. So now share the growing environment of Pleurotus eryngii.

The growth environment of Pleurotus eryngii is 1 1, which is a nutritious environment.

Pleurotus eryngii is a kind of edible fungus with strong ability to decompose lignin and cellulose, which needs rich nutrition, especially sufficient nitrogen source, and its mycelium grows vigorously and its yield is high. The main materials of artificial cultivation grow well on cottonseed hull, sawdust, bagasse, wheat straw and other substrates. Alternative cultivation and auxiliary materials, such as rice bran, bran, corn flour, cottonseed cake powder, calcium carbonate, sugar, etc. It can promote the growth and spread of hyphae and increase the appearance of mushroom buds.

2. Water environment

Pleurotus eryngii is drought-tolerant, but suitable water content is more conducive to growth and development and increase yield. In the mycelium growth stage, the suitable water content of the culture medium is 60%-65%, but it is not suitable to spray water on mushrooms during cultivation, and the water needed by mushrooms mainly comes from the culture medium, so the water content of the culture medium can be appropriately increased to 65%-70% during mixing. The relative humidity of air is about 60% in the mycelium growth stage, but it is 90-95% in the fruiting body differentiation stage after the primordium, and the fruiting body growth stage can be appropriately lowered to 85-90%.

3. Temperature environment

Temperature is the key to determine the success or failure of Pleurotus eryngii cultivation and yield. The temperature range of mycelium growth is 22-27℃, and the optimum temperature is about 25℃. When it is higher than 30℃, mycelium growth is not good.

Pleurotus eryngii is a kind of constant temperature solidified mushroom, and the temperature difference is too large, which is not conducive to the occurrence of primordium. Results The temperature range was 10- 18℃, and the optimum temperature was 12- 16℃. Below 8℃, the primordium will not appear. If it is higher than 20℃, abnormal mushrooms will easily appear, and diseases will occur, resulting in mushroom death. The growth temperature of fruiting body is 10-2 1℃, and the optimum temperature is 10- 18℃. Temperature control varies with strains, so special attention should be paid to understanding the characteristics of strains when introducing them.

4. Air environment

The oxygen demand of mycelium growth stage is relatively small, and low concentration of carbon dioxide can stimulate mycelium growth. With the growth of mycelium, the concentration of carbon dioxide in bags (bottles) gradually increased from 0.03% in normal air to more than 2%, and mycelium can still grow well. At present, sufficient oxygen is needed in the original base period, and the carbon dioxide concentration should be reduced to about 0.5%. Otherwise, the primordia do not differentiate and swell into spheres. Mushrooms need fresh air in the process of growth and development, and the carbon dioxide concentration should be less than 0.0 1%.

5. Lighting environment

The growth stage of mycelium does not need light, and the growth of mycelium will be accelerated in dark environment. At present, the growth and development of primordia and fruiting bodies need some scattered light, and the suitable light intensity is 500- 1000Lx.

6. pH environment

The pH range of mycelium growth is 4-8, and the optimum pH is 6.5-7.5. The optimum pH value at fruiting stage is 5.5-6.5.

The calorie of Pleurotus eryngii (calculated by 100g edible part) is 3 1 kcal (129 kJ). The calories per 100g of Pleurotus eryngii account for about 1% of the total daily calories recommended by the Nutrition Society of China.

Pleurotus eryngii is nutritious and contains protein, carbohydrates, vitamins and minerals such as calcium, magnesium, copper and zinc. Can improve human immune function, and has anticancer, hypolipidemic, gastrointestinal moistening, and skin caring effects.

Nutritional value: per 100g Pleurotus eryngii contains: calories (calories) 3 1.00 carbohydrate (grams) 8.30 fat (grams) 0. 10 protein (grams) 1.30.

Protein contains 18 kinds of amino acids, among which 8 kinds of amino acids necessary for human body are complete, so it is an edible fungus with high nutritional and health care value.

Varieties of Pleurotus eryngii: According to the morphological characteristics of fruiting bodies, the strains of Pleurotus eryngii at home and abroad can be roughly divided into five types: bowling type, stick type, drumstick type, short handle type and gray-black mushroom cover type. Among them, bowling and stick are widely cultivated in China.

Pleurotus eryngii has thick pulp, crisp texture, especially dense, solid and milky white stalk, which is completely edible. And the stalk is more crisp and refreshing than the hat. Known as "King of Pleurotus ostreatus" and "Pleurotus eryngii", it has a pleasant almond fragrance and tastes like abalone, which is suitable for fresh-keeping processing and is deeply loved by people.

Efficacy and function of Pleurotus eryngii

Pleurotus eryngii has the functions of reducing blood fat and cholesterol, promoting gastrointestinal digestion, enhancing immunity and preventing cardiovascular diseases.

1, Pleurotus eryngii can soften and protect blood vessels, and has the effect of lowering blood lipid and cholesterol.

2, improve immunity Pleurotus eryngii protein is the most important nutrient to maintain immune function, is the main component of white blood cells and antibodies.

3. Digesting Pleurotus eryngii contributes to the secretion of gastric acid and the digestion of food, and is suitable for the treatment of dyspepsia.

What is the efficacy and function of Pleurotus eryngii?

Pleurotus eryngii is rich in nutrition, fresh and delicious, so it has the reputation of "king of mushrooms". Pleurotus eryngii has high nutritional value. It is rich in protein, carbohydrates, vitamins and minerals such as calcium, magnesium, copper, iron and zinc, and can improve human immune function. In addition, Pleurotus eryngii has many functions, such as anti-cancer, lowering blood fat and blood pressure, moistening stomach and beautifying face.

Pleurotus eryngii is rich in protein, various essential amino acids, monosaccharides and nutrients, with low fat, low calorie and high nutritional value, which can enhance human immunity.

Pleurotus eryngii is sweet and cool, and enters the liver and stomach. It has the effects of invigorating middle warmer, regulating qi and resolving phlegm, improving human immune function and resisting the invasion of wind, dampness, dryness and heat. At the same time, it can also promote diuresis, strengthen the spleen and stomach, and promote digestion and absorption of gastrointestinal tract.
