Causes and Prevention of Death of Straw Mushrooms

Edible fungus in the production process of straw mushroom, often see the wilting death of a small mushroom, causing economic losses. The cause of death mushroom and preventive measures are summarized below.
First, poor ventilation Venturi mushroom is a high-temperature aerobic fungus, which requires sufficient oxygen during growth and development. During the cultivation process, in order to increase the temperature of the heap, sometimes the film is covered for a long time, so that the carbon dioxide in the pile causes too much oxygen, and the small mushroom is difficult to grow normally due to poor ventilation due to poor ventilation. Sow 1-4 days, pay attention to ventilation for half an hour every day, with the increase in the amount of mycelium and the emergence of needle mushroom, to increase ventilation.
Second, the lack of water Straw mushroom growth requires a lot of water, if the lack of water when building a pile sowing or mushroom no timely replenishment; grass is too thin and poor moisturizing properties, will lead to wilting mushroom. After sowing, when the mycelium is overgrown to form the needle mushroom, if it is not enough water, it can make up a heavy water; after the first tidal mushroom has to make up the water, the sunny grass needs to be sprayed to prevent the water in the material from evaporating.
Third, the temperature shock mushroom mushroom mycelium growth and fruit body development have different requirements for temperature, the general temperature of the mushroom is about 30 °C. However, sustained high temperatures during the summer season will cause death of small mushrooms in batches. Therefore, in the summer of summer, it is necessary to choose a shaded site for the cultivation of stockpiling materials, cover the grass quilt with material and spray more water, and put a shed over the top to cover the shade.
Fourth, the environment Acidic straw mycelium suitable for growth in the alkaline environment, when the pH value below 6 can be budding, but difficult to grow into mushrooms. After the first tidal mushroom is collected, 1% lime water or 5% grass gray water may be sprayed to keep the pH of the pile at about pH 8.
Fifth, the water temperature is uncomfortable Straw mushroom has certain request to the water temperature, if sprays the well water of about 20°C or sprays the ground water which the direct sunlight reaches above 40°C, until the second day the small mushroom will all wilt death. Spray water should be carried out in the morning and evening. The water temperature is about 30°C.
VI. Infection with bacteria, pests and diseases The use of raw materials such as straw, which has become mildew, as a culture material, and cultivation on unclean fields, will lead to a large number of pests, especially the cottonseed husk cultivation of straw mushroom, the mycelium in the material after the occurrence of ticks. Will soon disappear, so that all the mushrooms on the bed death. Adding 3% tea seed meal or 0.2% trichlorfon solution to the grass can control pests. Mushrooms are very sensitive to pesticides. When mushrooms appear, avoid using pesticides. Sang Wenxiu
