The growth and development of *Pleurotus marmoreus* (marmoreus oyster mushroom) is relatively slow, especially when compared to other common edible mushrooms like the regular oyster mushroom, hedgehog mushroom, and golden mushroom. The entire artificial cultivation process—from preparing the bacterial strain to harvesting the fruiting bodies—typically takes around 200 days, which is significantly longer than for other species. This extended cycle makes it more challenging to manage in a commercial setting.
One key stage in the process is the mycelium growth phase. After the container is fully colonized by the mycelium, it must be cultivated under specific conditions for over 40 days to achieve physiological maturity and ensure proper fruiting. This period is crucial, as improper conditions can lead to poor yield or even failure.
In northern China, relying solely on natural temperature conditions to complete the entire cultivation cycle within a suitable season is difficult, often resulting in inconsistent or unsatisfactory outcomes. However, there are some advantages to cultivating *Pleurotus marmoreus*. Its slow growth rate allows for better control and management, and the mycelium is quite resilient. It can survive in a wide range of temperatures, from -10°C to 38°C, and even when stored for six months under these conditions, its viability, yield, and quality remain largely unaffected.
By choosing the right seasons—primarily spring and autumn—it is possible to cultivate this mushroom twice a year, ensuring a continuous supply of high-quality mushrooms throughout the year. This adaptability and resilience make *Pleurotus marmoreus* an attractive option for growers looking to diversify their mushroom production.
Vitamins
Vitamins are essential organic compounds that bodies need in small amounts to function properly. They play a crucial role in maintaining good health and preventing various diseases. There are 13 essential vitamins that are classified into two categories: water-soluble and fat-soluble.
Water-soluble vitamins include vitamin C and all the B vitamins (thiamin, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, vitamin B12, and folate). These vitamins are not stored in the body and need to be replenished through diet or supplements daily.
Fat-soluble vitamins include vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver and can accumulate to toxic levels if taken in excess. Therefore, it is essential to consume these vitamins in moderation.
Each vitamin has a specific role in the body, and a deficiency in any of them can lead to various health problems. For example, vitamin C is essential for the immune system, wound healing, and collagen synthesis. Vitamin D is necessary for bone health and calcium absorption, while vitamin A is crucial for vision and skin health.
Of course animals need vitamins too, for example vitamins K3,medicine vitamins,Menadione,poultry vitamins,feed vitamins to boost immunity and growth.
