The latest course on cultivation techniques of Seafood Mushroom

Seafood mushroom, also known as jade mushroom, spot jade mushroom, Zhenji mushroom, etc., is a white mushroom family, jade mushroom is an edible fungus, crisp and tender texture, fresh taste, with sea crab flavor, fruiting body medium to large. Today, there are two strains of light gray and pure white, and the white strain is also known as "Baiyu mushroom" and "Yulong mushroom". Most of them are factory cultivated, so let's take a look at the cultivation techniques of seafood mushrooms.

Temperature condition

The medium-low temperature edible fungus of Pleurotus ostreatus occurs more than in late autumn and early spring under natural conditions. the mycelium growth temperature is 5: 30 ℃, the optimum is 20: 25 ℃, the mycelium no longer grows when it is more than 35 ℃ or less than 4 ℃, and can not survive above 45 ℃. The primordium formation needs 10: 16 ℃ lower temperature stimulation, and the fruiting body growth temperature is 13: 18 ℃.

Humidity condition

The water content of seafood mushroom culture material should be 65%, and the cultivation bag should be properly watered before mushroom production, so that the water content of seafood mushroom culture material can reach 70-75% in order to meet the growth of seafood mushroom. During the differentiation of mushroom buds, the relative humidity of the mushroom house should be adjusted to 9095%. During the fruiting body growth stage, the relative humidity of the mushroom room should be adjusted to 85% 90%. If the relative humidity is higher than 95% for a long time, the fruiting body is easy to produce yellow spots and soft texture.

Light condition

There is no need for light in the growth stage of the mycelium of seafood mushroom, direct light will not only inhibit the growth, but also darken the color of the mycelium, but a certain weak light is needed to promote the normal development of the primordium in the reproductive stage, and there is a certain correlation between light and the amount of primordium occurrence. Dark will inhibit the differentiation of the cap and produce abnormal mushrooms, and seafood mushrooms are easy to whiten in the dark, resulting in poor product texture. There is obvious phototropism in the process of fruiting body growth. The control of light in the stage of mushroom emergence is more ideal in 200~1000lx.

Air condition

Seafood mushroom is a moderate aerobic fungus, and the mycelium is not sensitive to air, but in the impermeable environment, with the extension of breathing time and the increase of carbon dioxide concentration, the mycelium growth rate will slow down, while in the process of fruiting body development, it is relatively sensitive to CCh, especially the differentiation of mushroom bud is very sensitive to carbon dioxide concentration. During the differentiation of mushroom buds, the concentration of carbon dioxide in the mushroom room is required to be 0.05-0.1%, and when the fruiting body grows up, the concentration of carbon dioxide in the mushroom room is required to be 0.2-0.4%. In practice, the concentration of carbon dioxide is often increased to an appropriate concentration by reducing ventilation. Close the window cover film to intermittently delay the opening of umbrellas, promote long handle, improve quality and increase the yield of mushrooms. However, if the concentration of carbon dioxide in the mushroom room is higher than 0.4% for a long time, the fruiting body is prone to deformity.

Acidity and alkalinity

Seafood mushroom mycelium in a certain range (pH5.0~8.0) of pH requirements are not strict, hyphae can grow in pH4.0~8.5, different strains have different requirements for pH, the mycelium growth stage of pH6.5~7.5 is better, so the actual operation of the medium is about pH8.0.

Nutritional condition

Seafood mushroom is a kind of low-temperature grass fungus or woody white-rot fungus, which has a strong ability to decompose lignin. The main nutrient substrates in nature include broad-leaved trees such as beech and seven-leaf trees. Due to the improvement of cultivation techniques, seafood mushrooms can also be cultivated only with the sawdust of Cryptomeria fortunei and pine trees. When cultivating seafood mushrooms with coniferous sawdust alone, we should pay attention to the degree of sawdust accumulation fermentation and the distribution of sawdust thickness. Also pay attention to the type and dosage of excipients (nutrients).

The cultivation conditions of seafood mushrooms are introduced here first, so let's take a look at the cultivation techniques of seafood mushrooms.
