What is the cause of yellowing and death of young Morchella mushrooms? Can young Morchella mushrooms spray water?

The cause of yellowing death of young Morchella mushroom is that the humidity is too high or too low, and the occurrence of diseases and insect pests will also lead to death. Young Morchella mushrooms can spray water, but it is not suitable to spray water when the temperature of the mushroom room is above 20 ℃. Every time the water is sprayed, it should be ventilated in time and do not spray stuffy water. In the mushroom bud or young mushroom stage, do not spray water directly on the mushroom body and mushroom bed, but need to spray water to the ground and air.

1. What is the cause of yellowing and death of young Morchella mushrooms

The main reason leading to the yellowing death of young Morchella mushroom is that the humidity is too large or too small, the general wet meeting causes poor ventilation, the young mushroom is easy to die by water stains and induce bacterial diseases, and if the humidity is too low, it is easy to dry up and die, at the same time, the temperature of the mushroom is too high, the humidity is too high, it will lead to the stimulated death of mushroom buds, and the occurrence of diseases and insect pests will also lead to death, or spraying drugs in the process of control will also lead to Morchella death.

Can young Morchella mushrooms spray water

1. Morchella young mushrooms can be sprayed with water, but it is not suitable to spray water when the temperature of the mushroom room is above 20 ℃. Every time, the water should be ventilated in time, and the water should not be sprayed directly on the mushroom body and mushroom bed during the mushroom bud or young mushroom stage. It is necessary to spray water to the ground and air to maintain the suitable humidity of the mushroom room. When the moisture of the mushroom tube or soil is insufficient, it is necessary to replenish water and adjust humidity in time.

2. Chemical control is not recommended at the stage of mushroom emergence, but trapping and artificial killing can be used. If pesticides must be used, only low toxic and residual drugs can be selected after mushroom harvest, and the concentration should be controlled within the allowable range. At the same time, we should pay close attention to the change of air temperature. It is necessary to adjust the temperature of the mushroom room according to the weather forecast to keep the temperature below 20 ℃. Avoid a sudden rise in the temperature of the mushroom room.

3. Morchella usually produces more mushrooms from early May to early June every year, and is distributed all over the world, especially in France, Germany, India, the United States and China. Secondly, it is sporadically distributed in the Soviet Union, Sweden, Spain, Mexico, Czechoslovakia and Pakistan.

4. Morchella is widely distributed in China, including three northeastern provinces in the north, Fujian, Guangdong and Taiwan in the south, Shandong in the east, and Xizang, Xinjiang, Ningxia and Guizhou in the west. However, the richness of Morchella species resources in different regions is different, and there are also great differences.

5. Among them, Gansu and Sichuan are relatively rich in Morchella species resources. Morchella is a very precious wild fungus. When selecting Morchella, it is generally superior to a large, dark color and spire. The pointed Morchella which can reach more than 5cm is the best Morchella, the market price is also more expensive and difficult to see, and the nutritional value is also higher than that of other forms of Morchella.
