Cultivation techniques of Pleurotus eryngii

Pleurotus eryngii gets its name because it tastes very good, smells like almonds and tastes like Baoyu. Pleurotus eryngii is rich in protein, which is more than 40%. It is also rich in vitamins, minerals and a variety of amino acids needed by the human body. Compared with other mushrooms, the meat of Pleurotus eryngii is tighter, more flexible and can be preserved for a longer period of time. Planting Pleurotus eryngii has good economic benefits, so let's briefly introduce the cultivation techniques of Pleurotus eryngii.

I. cultivation season

The most suitable growth temperature of Pleurotus eryngii is about 25 degrees, and the mycelium can grow in the temperature range of 6-35 degrees. The most suitable growth temperature after fruiting body formation is 15-21 degrees. Once the temperature reaches above 25 degrees and lasts for three days and exceeds 28 degrees, the fruiting body of Pleurotus eryngii will dry up and die.

The suitable cultivation period should be selected according to the suitable temperature for the growth of Pleurotus eryngii fruiting body, which can be cultivated when the outdoor temperature drops below 18 degrees in autumn. The cultivation bag can be made 50 days ago.

Second, control humidity

In the process of cultivating Pleurotus eryngii, it is necessary to ensure that the air relative humidity of the cultivation environment is 85-90%. Once the relative humidity of the air is higher than 95%, the fruiting body of Pleurotus eryngii is easy to become soft and rotten due to excessive humidity; once the relative humidity of the air is less than 70%, the fruiting body of Pleurotus eryngii is easy to dry and wither because it is too dry.

Pay attention to the water spraying measures taken to improve the relative humidity in the air, do not spray water directly on Pleurotus eryngii, it is easy to cause the bacteria to yellowing. Especially in high temperature weather, it can also cause Pleurotus eryngii to become soft and rotten.

Third, maintain ventilation

Pleurotus eryngii needs to maintain good ventilation during the mycelial cultivation stage. If the concentration of carbon dioxide in the air is too high, once it is higher than 0%, it will cause cell dysplasia. Especially in the hot and humid weather, it will cause the Pleurotus eryngii bacteria to become soft and rotten.

Fourth, control the lighting

Pleurotus eryngii needs light in the process of growth and development, and the light needed is scattered light, which is the best at 500-1000 lux. Too strong light will cause the bacteria to dry up, and too dark light will not be conducive to the normal development of Pleurotus eryngii.

5. Allocation of culture materials

Pleurotus eryngii does not contain chloroplasts and cannot produce its own nutrients through photosynthesis. It needs to rely entirely on organic nutrients to survive. Pleurotus eryngii has a strong ability to decompose cellulose and lignin. Pleurotus eryngii cultivation materials can provide nutrition for its growth and development, which contains nitrogen, carbon, auxin and other mineral ingredients.

The raw materials of cultivation materials are the mixture of sawdust, cottonseed husk and corncob, in which corn meal, gypsum and rice bran can be added as auxiliary materials.
