First, insufficient pre-wetness: Straw should be fully soaked to facilitate fermentation. Incompletely immersed straw requires a large amount of water when it is turned, and it cannot be supplemented before the second turning. It is difficult to make up afterwards, which will affect the growth of mycelium.

Second, the uneven rollover: Turning should be based on "the raw material put in the middle, put the clinker on both sides; put two in the middle, put the middle of the two" principle. However, many people do not follow the above principles when they turn over, so that the cultivation materials are not evenly fermented, and they cannot achieve the purpose of turning.

III. Unsatisfactory soil extraction: Some growers use untreated garden soil when covering the soil, and some add insufficiently cooked cow dung. This type of soil, with a large number of pathogens and eggs, can easily cause a variety of diseases and cause losses to mushroom growers.

IV. Adding urea when covering soil: New growers can easily equate mushroom growing with other crops habitually. Adding urea during overburden causes ammonia odor to cause death of mycelium.

5. Spraying “closed water”: Spraying “closed door water” at a high temperature in the early stage of mushroom cultivation will cause a high-humidity environment, causing the phenomenon of colonization of mycelium, death of bacteria and mushroom death. Late spraying "closed water", it is easy to make hyphae degradation, premature aging.

VI. Preventing diseases from happening in time: Some growers, due to lack of basic knowledge on how to discriminate and control pests and diseases, tend to prevent and control diseases and pests when they occur. As a result, they have missed the best period of prevention and control and have severely reduced their production.
