Eight Measures for Controlling Diseases in Bagging Mushrooms

The key to the quality of bagging mushrooms is the prevention and treatment of diseases during the germination period. Therefore, in order to increase the output of bagging mushrooms, the following eight measures should be taken during the bacteria-producing period: 1. Materials preferred for the production of raw and auxiliary materials such as cotton seed shells, corn cobs, sawdust, bran, rice bran and gypsum, calcium carbonate, etc. , should be fresh, dry, no mildew, no adulteration of nutrients. Before use, exposure to sunlight for 1-2 days, using ultraviolet rays to kill the pathogenic spores. 2. The rational use of material-based rice bran and bran is not only a good source of nitrogen for the development of mycelium, but also a carbon source. Their dosage should be appropriately increased or decreased with the change of the climate (relative humidity); if the amount is too large, it can be easily used by bacteria and cause pollution. Therefore, to properly control its content, generally 18% - 25%, high humidity season can be reduced to 18%. 3. Regulating the proportion of feed water Most of the water needed for the growth and development of edible fungi comes from the culture materials. Different filling containers and sealing materials are used in different cultivation seasons, and the ratio of feed water to water is not the same. Over-dried mycelium grows less and is delicate; over-wetness can cause mycelium decay and disease. 4, plug the invading mouth of the bottle or the bag must be a good mouth, Zhakou is very easy to cause the invasion of bacteria. 5, to prevent the deterioration of the culture materials should be equipped with a good fashion bag, and sterilized bacteria culture materials, otherwise it is easy to acid deterioration. 6, Thoroughly sterilize raw materials Whether it is the production of strains or clinker cultivation, the culture materials should be thoroughly sterilized, sterilization is not strict, often leading to the occurrence of diseases. Autoclaving should consider the effects of pressure, medium composition, pH, and porosity. For the sterilization under normal pressure, the following aspects should be considered: the degree of pre-wetness of the culture material, the self-producing biomass of the microorganism before sterilization, the placing method of the inner pot of the sterilizing pot, the relationship between the size of the sterilizing pot and the size of the wok , Sterilization time and steam flow degree. 7, adjusts the good pH The edible fungus has the certain request to the pH value, most likes the neutral or partial alkali environment. Therefore, in the preparation of the medium (feed), you can add an appropriate amount of superphosphate, etc., the medium (material) to adjust the acid, which can inhibit the occurrence of pathogens, but also for the edible fungi to provide a certain amount of phosphorus. 8, to strengthen the management of germination period 8.1 appropriate cooling culture. Most of the germs are hi and high temperature. Edible mushrooms except for straw mushroom should be cultured with proper temperature. Although the mycelium growth rate is slow, it is thick and strong, but the pathogens are significantly reduced. In particular, the raw material cultivation temperature should be below 20°C. 8.2 Hygroscopic culture. Edible fungus in the growth phase of mycelium requires the relative humidity of the air is generally lower than the pathogenic bacteria. Therefore, the relative humidity of the air during the germination period should be maintained at about 60%, which can effectively inhibit the occurrence of bacteria. 8.3 timely turn inspection. Two to three days after the inoculation, the first turn inspection was carried out and it was found that the pathogens infested should be promptly picked out.
