Where is the origin of shiitake mushrooms, and what are the requirements for the growth environment of shiitake mushrooms?
Mushroom cultivation originated in China and has been eaten for hundreds of years.

So, do you know where mushrooms are mainly distributed? Today, I will introduce it to you here, and also talk about the requirements for the growth environment of mushrooms and other related topics.

1. Where is the origin of mushrooms?

Mushrooms are mainly distributed in Hubei, Henan, Zhejiang, Fujian, Taiwan Province, Guangdong, Guangxi, Anhui, Hunan, Jiangxi, Sichuan, Guizhou, Yunnan, Shaanxi and Gansu.

Hubei is one of the main producing areas of mushrooms in China, and autumn planting in Suizhou is the main producing area. Yuan 'an County, Yichang is the main producing area of spring mushrooms in Hubei.

Henan is a big province producing bagged mushrooms in China, mainly distributed in Xixia County, nanzhao county and neixiang county. Lushi County, Sanmenxia City; Biyang County, Zhumadian City; The produced Lentinus edodes is unique and is one of the seven cultivation modes in China.

Second, what are the requirements for the growth environment of mushrooms?

Lentinus edodes is suitable for growing in dark and humid places with fertile soil, rich fungi and obvious biodiversity, specifically:

1. Temperature: The optimum temperature for basidiospores to germinate in wet state is 22-26℃.

The temperature range of mycelium growth is 5-24℃, and the optimum temperature is 24-27℃.

2. Moisture: The optimum moisture content for mycelium growth is 60-70%; In the process of fruiting body formation, the moisture content of mushroom wood should be kept at about 60%, and the air humidity should be 80-90%.

3. Nutrition: The main nutrients are carbohydrates and nitrogen compounds, as well as a small amount of inorganic salts and vitamins.

4. Illumination: the growth stage of Lentinus edodes mycelium does not need illumination, spore germination needs to be carried out under dark light or weak light, and the mycelium will form a dark brown film under strong light, and the suitable illumination is scattered light.

Third, new measures to increase mushroom production.

1, using acid protease inhibitors.

There are many kinks in the primordia of Lentinus edodes, but the number of Wei mushroom buds that can eventually differentiate and develop is limited.

The use of acid protease inhibitors can effectively improve the conversion rate and survival rate of primordia.

2. Mix with expanded perlite.

It can effectively improve the water retention capacity of the culture medium and improve the aerobic conditions of the culture medium.

Improve the resistance of mycelium to adverse environment, with good quality and high yield.

3, the use of hormones, mixed with hormones to soak, can significantly increase production.

The optimum concentration is 5- 10ppm, erythrosine 10-20ppm and acetic acid 5- 10 ppm(NAA).

4. Use synthetic nutrient solution.

At present, there are many similar synthetic nutrient solution products in various places.

It mainly contains trace elements such as nitrogen, phosphorus and potassium.

5. Apply micro-fertilizer gypsum.

Chemical gypsum (calcium sulfate) mixed with various trace elements can also increase production in different degrees.
