How much is tea tree mushroom per jin and measures to prevent culture bag contamination during cultivation

Tea tree mushroom (Agrocybe aegerita) is a kind of fungus with a very chewy texture and extremely delicious flavor, especially suitable for dry pot dishes or stir-fried with meat. Among mushrooms, tea tree mushroom is one of the varieties that is not cheap, and it is also very rich in nutritional value, deeply welcomed by consumers. So roughly how much does tea tree mushroom cost per jin? What measures are there to prevent bag contamination during cultivation?

1. Roughly how much does tea tree mushroom cost per jin?

There are fewer and fewer wild tea tree mushrooms now, and most are artificially cultivated, but the price is still not very cheap, and there are dried and fresh types. The price of fresh tea tree mushrooms is generally 5-10 yuan per jin, but fresh tea tree mushrooms cannot be stored for long, and most places sell the processed dried product. The price of dried tea tree mushrooms is naturally a bit higher, though regional differences are fairly large: some places sell them at 20-30 yuan per jin, while some places sell them at as much as 50 yuan per jin. In addition, tea tree mushrooms are also affected by factors such as variety, specification and purchasing channel, so everyone should compare more when buying. Below, let us look together: at the Dayanglu Agricultural and Sideline Products Wholesale Market in Chaoyang District, Beijing, the price of tea tree mushroom is 8.0 yuan/kg;

at the Dongwayao Wholesale Market in Hohhot, the price of tea tree mushroom is 7.0 yuan/kg;

at the Fujian Fuding Min-Zhe Border Farmers Market Center, 20.0 yuan/kg;

at the Huangjingtang Wholesale Market in Wuhan, the price of tea tree mushroom is 11.0 yuan/kg;

at the Chengbei Agricultural Products Wholesale Grand Market in Xishui City, Hubei, the price of dried tea tree mushroom is 58.0 yuan/kg.

2. What measures are there to prevent bag contamination during tea tree mushroom cultivation?

There are many reasons for contamination of tea tree mushroom bags; the common one is contamination by miscellaneous bacteria in the bag, which at that time destroys the nutrient substrate, and if the situation is relatively serious, it will cause the nutrient substrate to become moldy and spoiled, so that the entire crop of cultivated tea tree mushrooms will have no usable value. So why do miscellaneous bacteria appear in the bags?

First, the substrate has rotted, that is, the raw materials were not good to begin with, and the bagging time was too long, so that bacteria were produced. Second, the plastic bags are not good; they already had holes, or were not tied firmly, resulting in air leakage, loose thread ends or falling off. Third, the sterilization work was not thorough, resulting in failure to circulate and uneven heating. We can adopt the following measures to prevent and control contamination of the material bags.

1. Let the cottonseed hulls ferment with water one day in advance, then bring the material temperature to 70°C, so that miscellaneous bacteria can be effectively eliminated.

2. During the sterilization process, maintain the high-temperature state for one day; in between, cold water must not be added, the temperature must not be lowered, and the fire must not be turned off, so that miscellaneous bacteria can be thoroughly eliminated.

3. When we move the mushroom bags, our movements should be gentle, otherwise the bags are prone to rupture.

4. When inoculating, choose clear sunny weather and must follow strict aseptic operation.
