Distribution of producing area of Pleurotus ostreatus

Tea tree mushrooms are mainly distributed in the north temperate zone and also in the subtropics, but they are rare in the tropics. Extremely cold and hot climate conditions are not suitable for development. Tea tree mushrooms can be cultivated according to the general cultivation methods of wood-rot fungi. Let's take a look at the origin distribution of tea tree mushrooms.

Distribution of producing area of Pleurotus ostreatus

Tea tree mushrooms are mainly produced in Guangchang County, Jiangxi Province, Lichuan County, Jiangxi Province, and Gutian County, Fujian Province.

In addition, there is also production all over the country, and Kunming, Chengdu, Beijing and other places are large fresh mushroom producing areas. Lichuan County in Jiangxi Province is also an important producing area of tea tree mushrooms. Most of the products on the market come from Wulingyuan area of Zhangjiajie, the first national forest park in the country-- ten thousand mu tea garden. Natural tea tree mushrooms have been dried and manufactured. In the past year or two, tea tree mushrooms, especially Xiang Xiaowu's popular sales in South Korea.

The producing environment of Pleurotus ostreatus

Pleurotus ostreatus grows in and around the decaying roots of Camellia oleifera forest under natural conditions, and the growing season is mainly concentrated at the turn of spring and summer and around the Mid-Autumn Festival. It occurs more frequently in the regenerated forest after cutting down the old forest. Due to the hard wood and slow decay rate of Camellia oleifera, the growth cycle of tea mycelium is very long.

The occurrence of wild Pleurotus ostreatus is often affected by the precipitation of the previous year. That is, if there is a large amount of precipitation in the previous year and an appropriate amount of precipitation before March of the second year, there will be a large number of tea mushrooms in April and May of the second year. If there is less precipitation in the first year and drought in March of the second year, the occurrence of Pleurotus ostreatus is less even if there is more precipitation in April and May of the second year. It is precisely because of the long incubation time that the mycelium accumulates energy and accumulates sufficient nutrients for the growth and development of the fruiting body, thus forming a rare mushroom with rich nutrition, crisp and refreshing taste, excellent taste, beautiful appearance and unique aroma.

Nutritional value of Pleurotus ostreatus

The total amino acid content is 16.86%, and the eight essential amino acids for human body are complete.

4. Tea mushroom has the effects of tonifying kidney, diuresis, treating low back pain, wetting, invigorating spleen and relieving diarrhea. it is an ideal food for patients with hypertension, cardiovascular disease and obesity.
