The latest growth environment of Pleurotus eryngii

Pleurotus eryngii is named because of its almond flavor and fleshy taste like abalone. It is a new species of rare edible mushroom successfully developed and cultivated in recent years, which integrates food, medicine and dietotherapy, and has a high planting prospect. before planting, we need to understand the growth environment of Pleurotus eryngii, let's take a look!

Nutritive environment

Pleurotus eryngii is a kind of edible fungus with strong ability to decompose lignin and cellulose, which needs abundant nutrition, especially sufficient nitrogen source, luxuriant mycelium growth and higher yield. The main materials of artificial cultivation grow well on the substrates such as cotton husk, sawdust, bagasse, straw and so on. Substitute cultivation with auxiliary materials, such as rice bran, wheat bran, corn meal, cottonseed cake powder, calcium carbonate, sugar and so on, can promote the growth and spread of mycelium and increase the occurrence of mushroom buds.

Water environment

Pleurotus eryngii is more drought-tolerant, but the suitable water content is more conducive to growth and development and increase yield. In the mycelial growth stage, the suitable water content of the culture material is 60% Mel 65%, but because it is not suitable to spray water on the mushroom body during cultivation, the water needed for the mushroom body mainly originates from the culture material, so the water content of the culture material can be appropriately increased to 65% Rue 70%. The relative humidity of the air is about 60% in the mycelium growth stage, while 90-95% in the primordial post-fruiting body differentiation stage, and 85-90% in the fruiting body growth stage.

Temperature environment

Temperature is the key to determine the success or failure of cultivation and the yield of Pleurotus eryngii. The temperature range of mycelium growth is 22-27 ℃, and the optimum temperature is about 25 ℃, which is higher than 30 ℃. Pleurotus eryngii is a kind of constant temperature solidified mushroom, the temperature difference is too large, which is disadvantageous to the occurrence of primordia. The temperature range of mushroom emergence is 10-18 ℃, the optimum temperature is 12-16 ℃, the primordium will not appear below 8 ℃, and deformed mushrooms can easily emerge above 20 ℃, and diseases will occur, causing dead and rotten mushrooms. The growth temperature of fruiting body is 10-21 ℃, and the optimum temperature is 10-18 ℃. The control of temperature varies from strain to strain, so special attention should be paid to the characteristics of the strain during introduction.

Air environment

The oxygen demand during the mycelium growth stage is relatively small, and the low concentration of carbon dioxide has a stimulating effect on the mycelium growth. with the growth of the mycelium, the concentration of carbon dioxide in the bag (bottle) gradually increases from 0.03% of the normal air content to more than 2%. The mycelium can still grow well. At present, sufficient oxygen is needed in the primitive period, and the concentration of carbon dioxide should be reduced to about 0.5%. Otherwise, the primordium does not differentiate and expands into a ball. The mushroom body needs fresh air during the growth and development period, and the concentration of carbon dioxide should be less than 0.01%.

Lighting environment

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

PH environment

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