2016-09-05 16:34:20
Malformed mushrooms, “Mine mushroom”, “Red root mushroom” and other weird mushrooms are common to see during the growth period of mushrooms. In serious condition, they will affect quality and yield. Here are some occurrence reasons for these weird mushrooms: 
1. Malformed mushroom: main reason is poor ventilation, malformed mushrooms are easy to happen when the content of carbon dioxide in mushroom house exceeds 0.3%, the deep part of fruiting will cause malformed mushrooms which grow in interval of soil, people could give frequent ventilation to prevent malformed mushrooms.
1. “Mine mushroom”: too high humidity in mushroom house, excessive ventilation when transferring water of coarse soil, too late earthing of fine earth and low temperature are main reasons. People could master moderate amount of water when spraying water and give moderate ventilation to prevent “Mine mushroom”.
2. “Red root mushroom”: partial acid compost, excessive paddy water during the period of high temperature before fruiting, too much water content of overbarden, excessive glucose and poor ventilation are the mean reasons. People could adjust the PH Value of compost, keep the water content of earthing in between 22% and 25%, avoid water spraying in high temperature and give moderate concentration when topdressing.
3. “Rusty stain mushroom”: people fails to ventilate after spraying water on the surface of compost and mushroom house, too much humidity in mushroom house and tiny drops of water on the surface of mushroom will form rusty stains over time. People could open door, windows and ventilate for 30 to 60 minutes after spraying water to prevent “Rusty stain mushroom”.
4. “Hollow mushroom”: insufficient water spraying and dried overbarden will cause white medulla or even hollow mushroom. People could spray moderate water and keep relative air humidity in above 85% during the fruiting period to prevent “Hollow mushroom”.
5. “Forced-opening mushroom”: “Forced-opening mushroom” will appear when the temperature difference of day and night reaches 10 degrees or encountering cold air attack. People could cover straw matting to remain stable temperature and suitable humidity of mushroom house when finding sudden change in temperature.
6. “Pellicular mushroom”: close density, too high temperature or too low humidity will cause “Pellicular mushroom”. People could keep moderate temperature and humidity to prevent the occurrence of “Pellicular mushroom”.
