What is the distribution of mushroom producing areas in China at present?

In the history of our country, the main producing areas of mushroom cultivation with log cut flowers are distributed in the Yangtze River basin and the southern region. After sawdust cultivation and promotion, it reaches Hainan in the south, Heilongjiang in the north, Fujian and Zhejiang in the east and Xinjiang and Tibet in the west. It has been planted in 33 provinces, autonomous regions and municipalities directly under the central government, and has become an important growth point for economic development in mountainous areas and employment opportunities for about 5 million laborers. The midwest is still developing. The origin can be divided into Fujian, Zhejiang, Jiangxi, Central China, Northeast China and Southwest China. The output of Lentinus edodes in China mainly comes from sawdust cultivation, and the main producing areas of Lentinus edodes are Fujian, Zhejiang, Henan and Hubei in Central China. The yield of Lentinus edodes cultivated by Duanmu mainly comes from Central China, followed by Northeast China. Hubei, Shaanxi, Gansu, Heilongjiang, Anhui, Jiangxi, Guangxi and Fujian have a very small amount of wood cultivation.

The climate in Fujian, Zhejiang and Jiangxi provinces is warm in winter and hot in summer. Mushroom cultivation has a long history and wood resources are relatively scarce. Mushroom age strains are used. The main cultivation methods are outdoor shade shed frame mushroom without taking off bags, leaning on mushrooms after taking off bags, and covering soil with bags. In some places, the mushroom tube is insulated by an outer shade shed when it is over summer. The specifications of the bacterial bags are mainly 15cm× 60cm low-pressure polyethylene plastic bags. The mushroom products produced in Fujian, Zhejiang and Jiangxi provinces are mainly fresh-keeping mushrooms and smooth-faced mushrooms, and the proportion of flower mushrooms is low. At present, the mushroom sources of fresh-keeping mushrooms and Pleurotus ostreatus in China mainly come from this producing area.

The climate in Central China has four distinct seasons, with dry autumn and winter, hot summer and large temperature difference between day and night. The history of mushroom cultivation in sawdust bags is relatively short, the richness of mushroom resources varies from place to place, and the total accumulation of mushroom wood is relatively scarce. Lentinus edodes strains are mainly long-lived strains. The main cultivation methods are outdoor shed and big-bag-frame mushroom growing without taking off bags, and the mushroom tube is insulated by an external sunshade when it is over summer; The specifications of the bacterial bags are mainly 17 ~ 19 cm× 60 cm low-pressure polyethylene plastic bags. Mushroom products in central China include mushrooms, camellia and shiitake mushrooms, and mushrooms account for a high proportion. At present, Agrocybe aegerita and Agrocybe aegerita's mushroom sources in China mainly come from this producing area.

Southwest producing areas have mild climate, warm in winter and cool in summer, with little difference among the four seasons, short mushroom cultivation history and relatively rich mushroom wood resources. The use and cultivation methods of mushroom strains are the same as those in Fujian, Zhejiang and Jiangxi. At present, the scale of production in this area is not large, and the total output is not large.

Northeast producing area: Since the development of mushroom production in China, the history of cultivating mushrooms in sawdust bags in Northeast China is short, but its advantages are increasingly obvious, mainly as follows:

(1) Climatic advantages: severe cold in winter, short hot time in summer, low annual accumulated temperature, low air relative humidity, dry climate, large temperature difference between day and night, natural low-temperature sterilization once a year, relatively few pests and diseases, and more environmental conditions for producing organic mushrooms.

(2) Resource advantages Mushroom wood resources are relatively rich, the total reserves of mushroom wood are relatively large, the mushroom wood material is hard and the quality is good.

(3) Product quality advantage: The dried and fresh mushrooms produced in this area are mainly Pleurotus ostreatus and Camellia sinensis, followed by Pleurotus ostreatus, with a high proportion of Pleurotus ostreatus. At present, the mushroom sources of some flower mushrooms and camellia mushrooms in China mainly come from this producing area. Lentinus edodes grows from June to summer and autumn 10, which is equivalent to anti-season planting in the south.

In addition, at present, the strains producing mushrooms in Northeast China are mainly longevity strains; The main cultivation methods are not bag removal or bag removal in heat preservation greenhouse, but also the method of pressing mushroom material to cover soil to cultivate mushrooms. The specifications of the bacterial bags are mainly 17 ~ 18 cm× 60 cm low-pressure polyethylene plastic bags.
