Cultivation of edible fungus

Cultivation of edible fungus

The production of edible fungi is inseparable from the bacteria bags. As the saying goes, “one fungus, two bags, and three managements”, the importance of the quality of the fungus bags can be seen. There are two types of edible fungus bags, one is a polyethylene bag and the other is a bag of polypropylene. Polyethylene bag has the advantages of low temperature resistance and is not easily broken under low temperature conditions. Its disadvantage is that it is not resistant to high temperatures, it cannot be sterilized in a pressure cooker, and its air permeability is poor. Polypropylene bag has the advantages of high temperature resistance, it can withstand high temperatures above 130°C, and has good air permeability. Its disadvantage is that it is not resistant to low temperatures, poor impact resistance, and easy to damage when loaded. The selection of bacterial bags depends on the climatic environment and their own cultivation conditions. In addition, different strains have different regulations for use. If you use raw materials to cultivate edible fungi, it is best to use polyethylene bags, in addition to polypropylene bags. After deciding which bacterial bag to use, the next step is to identify the quality of the bag. First look at the appearance of the bag. The back cover of the bag is aligned with the seal, and the edges are generally hand-made and the edges are generally mechanically combined. The airtightness of the hand-stitched bag is not guaranteed, and the airtightness of the mechanically-combined bag is good. The other is to see if the bag's heat line is transparent. In the case of polypropylene bacilli bags, the polypropylene plastic film itself is transparent, and if the heat ray is not transparent, it must be an artificially-conformed bag. Heat-in-line opaque bags are not very effective in plasticizing. They are not only easy to leak, but they are hard and easy to fold. The quality of the differential bag depends on whether the color is pure and the color of the bag is transparent and soft. In addition, the quality of the bag can be identified by hand. After opening the bag, use your hands to circle and touch the thickness of the bag. If the bag is uneven and has thin spots, it will be easily damaged. The final measure is to weigh the bag and see if its weight is up to standard. For example, if it is a 17 cm 33 cm tertiary bacteria bag, the weight of each bag should be about 4.5 grams. In addition to “see, touch, and weigh”, the picking bag also has two tips: A small tip is to use a fingernail to pack a good air bag. If it does not leak, it means the bag The quality is good; another small trick is to put a bag of bacteria that has been filled with good air into a basin filled with water. Look for bubbles in the water. If there are no bubbles, it means that the airtightness of this bag is good. Clearance.
