Spring mushroom technology
In recent years, the cultivation of Agaricus bisporus has developed rapidly, but the mushroom house management technology is lacking after winter. To make the high yield of spring mushroom should pay attention to the following two aspects: First, for the dry winter (that is, during the winter, the bacteria bed is basically not sprayed, and the cover soil is in a dry state; when the temperature rises in the spring of the next year, the spray volume is increased to adjust the temperature again. The overwintering method of the winter bisporus spring tube should pay attention to the following points: Adjusting the temperature: The temperature gradually rises after the winter to the Spring Festival, and when the temperature is stable above 8°C, the mushroom house management should enter the management of the spring mushroom. During this period from low to high temperature, should be the main moisturizing temperature, to prevent excessive temperature difference between day and night. Adjusting the PH value: After the wintering of the culture material is consumed, the PH value decreases, and the pH value needs to be adjusted to 7-8 with 5% lime water. Moisture control: After the winterization of the culture material is reduced, water is required to be sprayed with 5% lime water to spray the bacteria bed. The water sprayed onto the bed surface is required to seep to the bottom of the bed, but it does not leak, spraying 4.5-9 liters per square meter, spraying water 7 - After 10 days, increase the amount of water spray again. Later, with the gradual increase in temperature, the mushroom bed sprays about 2.5 liters of water per square meter per day when it comes to fruiting. It requires the cover soil to be flattened and can be crushed, but it is not sticky, and there is a crack after coarse soil pinching. The air humidity should be maintained at 90% - 95%. After the temperature is below 18 °C, spray 0.5 liters per square meter per day. Prevent pests and diseases: In combination with regulating humidity, use 5% formaldehyde to spray culture materials to the bed before mushrooming to prevent the occurrence of Agaricus bisporus virus disease. Before the mushrooming, the 1:1 ∶ 50 Bordeaux mixture (ie, copper sulfate: quicklime: water = 1:1:50) is used to spray the mushroom bed. Later, 5% carbendazim WP or 40% carbendazim suspension can be used. 400-600 times liquid mushroom bed, control of brown mushroom black spot. In combination with regulation of moisture, 80% of dichlorvos 1000 times or 2000 times of Kedeite is used to spray the two sides of the mushroom bed, frame materials, and mushroom house walls to prevent the occurrence of insecticidal damage, while removing the mushrooms from the mushroom bed. Spring damage and mushroom fly are more likely to occur and management should be strengthened. Nutrition: As long as the mushroom is harvested, if it is not supplemented with nutrients, continuous mushrooming will result in the accumulation of sufficient nutrients and the occurrence of thin skin mushroom, hollow mushroom, and even death of small mushrooms in batches. Nutrients need to be supplemented with nutrients, so after each mushroom has been harvested, it is necessary to stop spraying for 4-5 days to fully maintain the bacteria. Then combined with water and nutrition, that is, adding some nutrient solution when replenishment, you can spray glucose, soy milk. Mushroom root plus 20 times the water boiled filtrate +0.2% sugar + 0.1% potassium dihydrogen phosphate, etc. to promote hyphae robust, in order to increase production and quality. The bacteria bed can spray 0.5%-1% saline, not only can make the mushroom whitening, but also can accelerate the kinks. When the temperature reaches above 22°C, the bacteria bed will no longer produce mushrooms, and the water management will stop. Second, for wet overwinter (that is, during the winter every other week or so spray water once per square meter 0.25-0.5 liters, so that the cover is not white, pinch flat, broken broken, was semi-dry state, moisture content of 15% Left and right) the spring tube of Agaricus bisporus should not adopt the method of increasing the amount of water spray. The time of water transfer is 5-10 days later than the dry winter. Only the light spraying method can be used to gradually adjust the soil moisture and wait until the bacteria bed hypha When germinating again and the temperature is stable above 10°C, transfer to normal water transfer, keep soft soil loose, coarse soil loose, air temperature is 80%-85%, prevent mycelium from shrinking due to low temperature and large amount of water spray. . Other measures are the same as for the overwintering winter mushroom spring tube.
