Morel Production Associated with Soil Nitrogen-Fixing and Nitrifying Microorganisms

Summary

This research investigated how soil microorganisms affect the cultivation of morel mushrooms, which are highly valued edible fungi. The study found that certain beneficial bacteria that help with nitrogen processing in soil promote better morel growth, while harmful fungi can reduce yields. This has important implications for improving morel cultivation success. Impacts on everyday life: • Better understanding of how to grow morels could make these expensive mushrooms more widely available and affordable • Insights into beneficial soil microbes could help improve sustainable agriculture practices • Knowledge of harmful fungi could help prevent crop losses in mushroom farming • The findings contribute to more efficient food production systems • Understanding soil ecology helps preserve natural mushroom habitats

Background

True morels (Morchella spp.) are highly prized edible mushrooms with great economic and scientific value. While artificial cultivation has expanded rapidly in China, about half of morel cultivation attempts fail to bear fruit or show low reproduction rates. Soil-associated microbes are known to influence mushroom growth and development, but research on microbial communities related to morel cultivation across different regions remains scarce.

Objective

To investigate the diversity and structure of soil fungal and bacterial communities in morel-cultivating areas and reveal differences in soil microbial abundance and structure after morel cultivation. Additionally, to assess whether the soil microbial community is related to morel yield and identify indicative soil fungal and bacterial communities related to morel fructification.

Results

The study found that soil biodiversity showed a downward trend after morel cultivation compared to bare soil. There were no significant differences between control soil and soil after one-year suspension of sowing, indicating microbial community restoration. In high-yield soils, nitrogen-fixing and nitrifying bacteria like Arthrobacter, Bradyhizobium, Devosia, Pseudarthrobacter, Pseudolabrys, and Nitrospira were prominent. Low-yield soils showed higher proportions of pathogenic fungi including Gibberella, Microidium, Penicillium, Sarocladium, Streptomyces, and Trichoderma.

Conclusion

The research revealed that nitrogen-fixing and nitrifying microorganisms may promote morel fructification, while pathogenic fungi can seriously affect morel yield. The study provides valuable insights into the interaction between morel production and soil microbial communities, offering useful microbial resources for future morel cultivation. Further research is needed on the relationship between morels and nitrogen-cycling microorganisms, as well as the identification and control of potentially pathogenic fungi.
