1. Replace varieties and enhance disease resistance. Practice has proved that in the same area, breeding the same variety repeatedly, the incidence rate is high, it is best to replace the new varieties once a year, in particular, to breed varieties with strong disease resistance, and lay a solid foundation for a good harvest.
2, the correct discharge to prevent burning bacteria. In recent years, most of Pleurotus ostreatus adopts wall-shaped three-dimensional casing, which is easy to manage, has high yield, and is convenient for replenishing water. However, the disadvantage is that it is not easy to disperse temperature, and it is easy to burn bacteria, because the soil itself also bears germs. Prone to the disease. It is best to adopt a method that does not cover soil, single row discharge, and two oysters. The layer should be separated from the layer by small bamboo rods or sorghum stalks, and a certain gap should be left between the bags and bags to facilitate cooling. As long as the water is replenished in a timely manner, the single discharge can also achieve high yields by strengthening management. If you take soiling and mushrooming, you should also pay attention to the following: (1) Strictly sterilize the soil, and use formaldehyde to moisten the soil; (2) Cover wet soil, and do not apply mud. Because the synthetic clay is easy to be compacted and has poor air permeability, it cannot satisfy the growth of the mushroom. Demand of oxygen, exhaust gas is not easy to discharge in time; 3 water in the tank to be appropriate, excessive water, excessive water in the medium, resulting in hyoid hypoxia, hyphae is weak, disease resistance is poor, prone to disease.
3, comprehensive prevention and control, eliminate bacteria source. 1 During the germination period, spraying alkali water every 10 days will not only effectively sterilize, but also remove the acidity of the mushroom house so that the mycelium will grow stoutly and have strong disease resistance; 2 Sterilize the carbendazim in the space and wall once every day. Collect one mushroom each time, and spray 1 gram of carbendazim once again on the material surface, space, and wall. 3 During mushrooming, keep the mushroom house clean. , Clear the mushrooms in time to eliminate hidden dangers; 4 waste materials should be promptly removed after the mushroom, away from the mushroom house; 5 mushroom house timely disinfection and sterilization can be fire alkali, lime sneezing, sulfur ignited fumigation and other methods, such as Conditions can also be used to sterilize by fire, to create good conditions for the next cultivation, as long as the measures are reasonable, it can completely avoid the disease.
