Key technology for wintering management of Agaricus bisporus

1 When the cockroach cockroach bed is overwintering, firstly, a snoring measure should be carried out on the mushroom bed to improve the gas permeability of the bacteria bed, remove the bad gas and harmful metabolites in the bacteria bed, and make the bacteria bed and bacteria early. Silk has the opportunity to rejuvenate. Requirements and practices for snoring: Use bamboo sticks or sharpened wooden sticks or pointed steel bars to poke up the bottom of the bed. The hole distance is 12-15cm. It is better to poke the soil layer loosely. The film is applied to prevent the upper culture material from falling onto the lower bed.

2 Water spray topdressing in winter, the climate is dry, the water in the bacteria bed is still slowly evaporating. In order to prevent the bacterial bed from drying out and affecting the normal metabolic activity of the hyphae, the mushroom house should generally adopt the wet winter method. Use the dried mushroom house, during the winter, you should also pay attention to the water content of the bed, and pay attention to moisturizing, if necessary, spray water properly. The winter mushroom house should be sprayed with water to match the top dressing. If the mycelium is weak, spray it with 1% glucose water, or 0.25% urea plus 0.5% potassium dihydrogen phosphate. If the growth of mycelium is normal, it is better to use pig, cow and human urine dilutions. The water spray should be at noon on a sunny day. It is not suitable for top dressing at room temperature below 0 °C to prevent the hyphae from being damaged by freezing. During the winter, spray 2% lime clear liquid 1-2 times to adjust the pH of the soil layer. Linyi Fertilizer Network Copyright

3 Insulation and ventilation In winter, the temperature is low, and the viability of mycelium is obviously weakened. In order to maintain the slow growth of mycelium, the mushroom house must be strengthened. The temperature should be 3-4 ° C, and pay attention to a little ventilation.

4 The bed cleaning of the bacteria bed includes a lot of work such as loosening the soil, removing the old roots, removing the waste, and replenishing the soil. Before the bacteria bed is finished, stop the water and increase the ventilation, so that the fine soil moisture is dried, so that the loose soil is not easy to be broken when it is turned, and it is completed on the day of the bed. After finishing, it is necessary to combine water spray, top dressing and cover fine soil (6-7kg/m2 with fine soil to protect the growth of regenerated hyphae). When the bed is finished, it should be treated according to the specific situation. A kind of mushroom bed should be simply treated. Firstly, the lime powder is evenly sprinkled on the surface of the soil layer. The dosage is about 13kg/m2. The short nails are used to loosen the fine soil, and then the old hyphae and dead mushrooms in the soil layer are removed. Then arrange the bed surface and make up the fine soil. For the second type of bacteria bed, the fine soil should be scraped to the side first, then the bamboo layer or the fork is inserted obliquely into the soil layer to smash the coarse soil, and the yellow hyphae, the old mushroom root and the aging non-regenerating dry bacterium are sorted. Cable, then flatten the coarse soil, cover the fine soil, and evenly spread the lime powder, 15kg per 100 square meters, and then add new fine soil. It is also possible to sprinkle a small amount of newly prepared culture material on the coarse soil, and dig some strong white hyphae from the bottom culture material as a strain, sow it on the new material, then cover the fine soil, and then spray the bed surface once. Water or lime clear solution. 3-5 days after spraying water, cover a layer of fine soil. In addition, the mushroom house should be cleaned, the ground should be kept clean, the ground should be replaced with lime powder, and the wall can be brushed with lime slurry once. Spray insecticide liquid once every 20 days to reduce the wintering amount of pests and diseases. When the spring of the next year, control the temperature, adjust the water, in order to stabilize the high yield. Linyi Fertilizer Network Copyright
