Where is the origin of Agrocybe aegerita? Can you elaborate on it?

Agrocybe aegerita is a kind of wild mushroom that grows in tea buds in the mountainous and dense forest area of Guangchang, Jiangxi Province. Agrocybe aegerita is mainly distributed in the north temperate zone, and it is also distributed in the subtropical zone, but it is rare in the tropical zone. Extremely cold and hot climate conditions are not suitable for the growth of Agrocybe aegerita. Agrocybe aegerita can be cultivated according to the general cultivation method of wood rot fungi. Agrocybe aegerita grows in natural conditions in the small tree Camellia oleifera forest and its surrounding rotten roots, and the growing season is mainly concentrated at the turn of spring and summer and around the Mid-Autumn Festival. It is more common in the regeneration forest after cutting down the old forest. The growth cycle of Camellia oleifera mycelium is very special because of its hard wood and slow decay. According to the investigation, the occurrence of wild Agrocybe aegerita is often affected by the precipitation in the previous year. That is, there was a lot of precipitation in the previous year, and there was moderate precipitation before March of the next year, so a large number of Agrocybe aegerita would occur in April and May of the next year. If there is less precipitation in the first year and drought in March of the second year, then even if there is more precipitation in April and May of the second year, the occurrence of Agrocybe aegerita is less. It is precisely because of the long spawning time that it is conducive to the accumulation of mycelium energy and the sufficiency of nutrients needed for the growth and development of fruiting bodies that Agrocybe aegerita, a rare edible fungus with rich nutrition, crisp and delicious taste, beautiful appearance and unique aroma, has been formed. Camellia oleifera is one of the main oil-bearing cash crops in China, which is distributed in subtropical evergreen forest belt in acid red soil and yellow soil. Its fruit camellia seeds are rich in camellia oil. Tea oil is pure and fragrant, refreshing; Another fruit, Agrocybe aegerita, is the "King of Mushrooms", which is rich in flavor. The distribution range of Camellia oleifera includes Wuyishan area in Jiangxi and Fujian, hilly areas in Hunan, Hubei and Zhejiang, Yunnan-Guizhou Plateau and Guizhou mountainous areas. The annual average temperature in these places is 10~20, but most of them are above 18. In June 5438+ 10, the average temperature is above 4, and it can reach 10 in the south. Generally, there is no severe cold in winter and the frost-free period is more than 300 days. Most of the annual precipitation is above 1500mm. The warm and humid climate, fertile soil and foggy seasons are conducive to the dry rot of Camellia oleifera, which is extremely suitable for the growth and development of Agrocybe aegerita mycelium and the formation of high-quality mushrooms. It is precisely because of these unique and superior natural geographical environments that Agrocybe aegerita, a rare delicacy in the world, has been created.
