Pleurotus eryngii bag production
2020-10-28 12:15:35
Pleurotus eryngii belongs to a variety of high-grade edible fungi, and the production efficiency is relatively satisfactory. In recent years, many mushroom farmers have been attracted to the ranks of planting Pleurotus eryngii. However, many of the farmers' calls and letters reflect that there are few high-yield cultivation techniques for Pleurotus eryngii. To this end, this newspaper organized the special edition of the Pleurotus eryngii plantation and hopes to help everyone.
First, the basic raw and auxiliary materials Pleurotus eryngii is a kind of wood rot fungi, hi hi hard material matrix, generally in the production of cotton seed shell as the main material, or with broad-leaved wood chips. In recent years, due to the excessive increase in the price of cottonseed hulls, some farmers use corn stover and other straw materials as substitutes, and the effect is acceptable. Most of the accessories are mainly wheat bran, rice bran and other organic materials, and some of them are supplemented with appropriate amounts of inorganic materials, and microelements are used to supplement micronutrients. The production effect is very good.
Second, material bag production
1. Basic formula. Formula One: cotton seed hull 200 kg, wood chips 30 kg, wheat bran 20 kg, bean cake 2 kg, lime powder 3 kg, compound fertilizer 2 kg, gypsum powder 2 kg, edible fungus three-dimensional nutrition essence (condiment type) 120 grams. Formulation 2: wood chips 160 kg, cotton seed hulls 40 kg, wheat bran 30 kg, corn flour 20 kg, bean cake 4 kg, lime powder 4 kg, gypsum powder 3 kg, compound fertilizer 3 kg, edible fungi three-dimensional nutrition essence (mixing materials Type) 120 grams. When wood chips are used as raw materials, it should be stuffed and boring after the ingredients are mixed. It can be a few hours in a short time and about 3 days in a long time, making the water softening.
2. Base material bagging. Generally flat width 16 ~ 20 cm specifications is appropriate, each bag of dry material about 400 to 500 grams. A foldable bottom bag can be selected when using a mushroom, and the polypropylene tube can be cut off when the two pieces of the mushroom come out. Pocket mouth sets of plastic collars, plus tampon or direct zigzag can be. Loading materials should be uniform, elastic and uniform, not loose, otherwise the hyphae in the loose place are easy to break, and the side wall mushrooms are easy to occur, and the tightness at the tight end is not good, so it is easy to cause uneven distribution of the fungus, and the mushrooms are not uniform. , it is difficult to unified management. It is recommended to use a bagging machine operated by a person to facilitate mastery. Another advantage of using the bagging machine to operate is that the ergonomics is high and the work can be completed in a shorter time so that the sterilization process can be entered as soon as possible to prevent the bag from being sterilized for a long time under high temperature conditions, resulting in the base material. It is rancid and delays production, causing waste.
3. Sterilization. The method of autoclaving is preferred, or high-pressure steam is sterilized under normal pressure. However, most producers do not have such equipment. Therefore, normal pressure sterilization can be used in production. Generally, the bag is kept at 100°C for 6 to 12 hours. Can, if it is not flow operation, can make it warm overnight, sterilization effect is better.
Third, inoculation
1. Inoculation operation. When the bag cools below 30°C, it is moved into the inoculation room and the drug can be inoculated after fumigation and sterilization for 40 minutes. Generally, about 15 bags per 500 ml bottle or 750 ml bottle strain can be connected, and about 30 bags can be inoculated using the single bottom inoculated bag; the bacteria species should be accessed as much as possible to reduce the fine-grained bacteria species to accelerate the germination as soon as possible. Let the mycelium cover the material surface to minimize the pollution and increase the germination success rate.
Inoculation and sterilizing machines are commonly used for inoculation. Inoculation can be performed 10 minutes after starting up. The traditional method of fumigation of drugs is abolished, the production cost is reduced, the injury and residue of drugs to the human body are eliminated, and the inoculation operation is greatly improved. Work efficiency.
2. Fungus management. Before the training room (shed) is put into use, strict elimination work shall be carried out. Generally, the disease may be sprayed once and sealed for two consecutive days. The doors, windows and ventilation holes are all encapsulated with insect-proof nets to prevent insects from entering. After the inoculated bacteria bags are moved in, the culture racks shall be coded with 3 to 5 layers, which shall not be too high. In particular, when the temperature is high, attention shall be paid to the heat generation of the bacteria bags during germination; the ground watering and the wall shall be adopted in the room (shed). Space and water spray, etc., to make the room temperature as low as possible, winter germs should try to make the room temperature rise and maintain stability, generally should regulate the temperature in the range of 15 °C ~ 30 °C, the best 25 °C; humidity of about 70%, and There is a small amount of ventilation, although the mycelium of Pleurotus eryngii can tolerate higher concentrations of carbon dioxide, but the development of the mycelium is still better than the fresh air; in addition, the enclosed culture chamber (shed) makes the bacteria bag germinate under dark conditions, which is both bacteria The physiological needs of silk are also one of the effective measures to prevent the entry of pests. Generally about 40 days, mycelium can be full of full bags.
3. After ripening culture. After the bacterium bags are full, try to lower the temperature, and then maintain the hypha culture period of about 15 days, then you can achieve the hyphae after ripening, and lay a good material foundation for the mushroom.
